The Visionstar SJD-C15A is a battery-powered dental X-ray generator built around a DC high-frequency inverter running at 200 kHz. Rated power is 90 W, tube voltage is fixed at 60 kV and tube current at 2 mA, with a DC 16.8 V internal output rail. High-frequency operation holds the kilovoltage waveform close to constant potential through the exposure, which produces repeatable receptor density and keeps the proportion of low-energy photons in the beam smaller.

Geometric sharpness comes from a 0.4 × 0.4 mm focal spot. Paired with correct paralleling technique, that focal spot resolves the trabecular pattern, lamina dura and apical detail that root depth assessment, endodontic length verification and pre-surgical implant site review depend on. The manufacturer positions the unit specifically for oral pre-treatment diagnosis of internal structure and root depth, including work in dental implant surgery.

Exposure control runs through an LCD panel with manual switches set into the shell surface, plus a wireless handheld remote that releases the exposure from a distance the operator chooses. Exposure time is adjustable from 0.2 to 3.2 seconds, spanning direct digital sensor values through to phosphor plate and film technique across anterior, premolar, molar and bitewing regions.

Internally, the control electronics are consolidated on a central PC board, and the tube assembly uses insulated vacuum construction with a sealed protective moulding. The 14.8 V 6600 mAh lithium pack delivers approximately five hundred exposures on a full charge, and the manufacturer rates the pack for roughly one thousand charge and discharge cycles across its service life. Charging accepts AC 100–240 V ±10%, so the unit runs on UK mains directly.

Specified operating conditions are 5–40 °C ambient temperature and below 75% relative humidity. The unit is designed to feed an intra-oral digital X-ray imaging system. Medigear.uk can arrange supply, delivery, commissioning, staff familiarisation and service cover for the SJD-C15A across the United Kingdom.

Intraoral radiography underpins routine diagnosis across UK dentistry, and the SJD-C15A is configured for that daily workload. In general dental practice, it supports bitewing caries detection, periapical assessment of apical pathology, endodontic working-length and obturation verification, periodontal bone-level review, and root morphology assessment ahead of extraction. Fixed 60 kV and 2 mA operation with variable exposure time maps directly onto region-by-region protocols agreed with a Medical Physics Expert and recorded in local diagnostic reference levels.

Implant dentistry makes particular use of intraoral views for site review, healing assessment and abutment-level verification, and the manufacturer positions the unit for pre-treatment assessment of internal structure and root depth. UK practices work within the justification framework of IR(ME)R 2017, so intraoral views are selected where they answer the clinical question and sectional imaging is requested where three-dimensional anatomy is at issue.

Community dental services and special care dentistry teams working under NHS commissioning depend on equipment that reaches the patient. People living with advanced dementia, profound learning disability, motor disorders or palliative care needs are often unable to transfer to a fixed dental chair, and assessment in a care home lounge or at the bedside is the realistic route to diagnosis. Battery capacity of roughly five hundred exposures per charge suits that pattern, provided off-site radiation protection arrangements have been agreed with the practice's Radiation Protection Adviser in advance.

Orthodontic practices use periapicals for root resorption monitoring during active treatment. Paediatric dentistry benefits from short exposure values and from settling a child in position before the beam is aligned. Dental education, outreach programmes, prison dental services and expedition dentistry all rely on battery-driven equipment.

Guidance from the College of General Dentistry and UKHSA Dental X-ray Protection Services remains the reference point UK practices work to, alongside HSE enforcement of IRR17.

Operator distance at the moment of exposure

The wireless remote releases the exposure without the operator's hand on the shell, giving them freedom to choose their standing position within the arrangement their Radiation Protection Adviser has assessed. For staff taking a high daily volume of radiographs, that flexibility is worth having designed into the equipment.

A full working day between charges

Approximately five hundred exposures from a single charge covers a general practice list comfortably and supports a complete round of community visits. A rated life of around one thousand charge cycles makes the pack a long-interval consumable for budget planning.

Consistent output from high-frequency drive

A 200 kHz DC inverter holds tube voltage close to a constant potential across the exposure. Consistent output translates into consistent receptor density, which reduces retakes caused by under- or over-exposure and keeps cumulative patient dose lower across a course of treatment.

One variable for the operator to set

Tube voltage and tube current are fixed at 60 kV and 2 mA by design. The operator sets exposure time only. A single adjustable parameter shortens the training curve for newly qualified operators and reduces the scope for setting error under time pressure.

Detail that supports root-level decisions

The 0.4 × 0.4 mm focal spot limits geometric unsharpness, which is what makes lamina dura, trabecular pattern and apical anatomy readable. Those are the structures that root depth assessment, endodontic length verification, and implant site review actually turn on.

Built for a digital record

Designed to feed an intra-oral digital X-ray imaging system, the unit drops into an existing sensor and image-management workflow, with an exposure range that reaches the short values direct sensors require.

Sealed, consolidated construction

Control electronics sit on a central PC board, and the tube assembly uses insulated vacuum construction with sealed protective moulding. Fewer discrete assemblies means fewer service points and a shell that stands up to daily surgery handling.

Compact storage and secure keeping

A 330 × 310 × 230 mm packed envelope stores in a lockable cupboard without difficulty, which supports the physical security duties that apply to X-ray equipment under IRR17 and keeps the unit out of circulation between sessions.

UK supply, commissioning and service through one route

Medigear.uk can arrange listing, supply, delivery, installation, commissioning, staff familiarisation, service cover, planned maintenance and quotations for the SJD-C15A across the United Kingdom, with site survey support where a practice wants the radiation protection conversation scoped before order.

Wireless remote exposure trigger

A handheld remote releases the exposure, letting the operator select their position during the shot within their assessed radiation protection arrangement.

90 W rated power

The generator is rated at 90 W, sizing the power supply to sustain the fixed 60 kV / 2 mA output across the full exposure time range.

Fixed 60 kV tube voltage

Operation at a fixed 60 kV sits in the established kilovoltage range for intraoral dental radiography and supports adequate contrast for caries and periapical assessment.

Fixed 2 mA tube current

Holding tube current constant means the exposure product is governed entirely by time, which simplifies protocol design, audit and staff training.

200 kHz DC high-frequency inverter

High-frequency drive produces a near-constant potential waveform, giving steadier output per exposure and a beam with proportionally fewer low-energy photons.

0.4 × 0.4 mm focal spot

A small square focal spot limits geometric unsharpness at the receptor, underpinning fine detail visibility on periapical views.

0.2–3.2 second exposure range

A sixteen-fold span of exposure time covers direct digital sensors at the short end through to phosphor plate and film technique at the long end.

LCD panel with ready and exposure indicators

The display presents the active exposure value and machine state in one legible view, with ready and exposure status signalled through the cycle.

Manual switches set into the shell

Surface-mounted buttons give positive tactile feedback under gloves and present a wipeable control face for routine surgery decontamination.

Central PC board architecture

Control electronics are consolidated onto a single board, reducing internal interconnection and the number of discrete service points.

Insulated vacuum tube assembly with sealed moulding

The tube assembly uses insulated vacuum construction inside a sealed protective moulding, protecting the high-voltage section from moisture ingress and handling shock.

14.8 V 6600 mAh lithium battery

A high-capacity lithium pack holds voltage well through the discharge curve, supporting consistent output from the first exposure of a session to the last.

Approximately 500 exposures per charge, ~1000-cycle life

Manufacturer-stated capacity per full charge and rated charge-discharge cycle life, both useful figures for planning charging routine and consumable budget.

DC 16.8 V internal output with universal AC charging

The internal rail runs at DC 16.8 V, charged from AC 100–240 V ±10% at 50/60 Hz, so the unit works on UK mains directly and internationally with a plug adaptor.

Specified environment: 5–40 °C, below 75% RH

Published ambient temperature and humidity limits define where the unit can be operated and stored, which matters for outreach and vehicle-based work.

FAQ

Frequently Asked Questions

Everything buyers need to know about sourcing medical equipment through MediGear.

The remote releases the exposure without the operator's hand on the shell switch, which gives them freedom to choose their standing position and distance during the exposure. Operator dose falls with distance, so this matters for staff who take a high volume of radiographs. Your Radiation Protection Adviser will set the operator position and any shielding requirement that applies in your surgery, and the remote should be used inside that assessed arrangement rather than as a substitute for it.

The manufacturer states approximately five hundred exposures from a full charge of the 14.8 V 6600 mAh lithium pack, with a rated service life of around one thousand charge and discharge cycles. Actual counts depend on the exposure times used and on standby duty cycle. For a general dental practice, that capacity comfortably covers a full working day, and for a community team it supports a complete round of visits.

The Ionising Radiations Regulations 2017 require employers carrying out dental X-ray work to register with the Health and Safety Executive, appoint a Radiation Protection Adviser, nominate a Radiation Protection Supervisor and complete a radiation risk assessment. The Ionising Radiation (Medical Exposure) Regulations 2017 add the appointment of a Medical Physics Expert, justification and optimisation of every exposure, and documented training for referrers, practitioners and operators. A critical examination is also required when the equipment is put into service. These duties sit with the employer.

Treat it as manufacturer marketing positioning, not as a UK regulatory statement. Every dental X-ray generator emits ionising radiation by design, and the doses that actually apply in your surgery depend on exposure factors, receptor speed, collimation, operator position and shielding. Have your Radiation Protection Adviser and Medical Physics Expert measure and record the real figures for your installation, and set your local diagnostic reference levels from those measurements.

The manufacturer positions the unit for pre-treatment assessment of internal structure and root depth, which covers intraoral views used in implant site review, healing checks and abutment-level verification. Intraoral radiography gives two-dimensional information only. Where bone volume, nerve position or three-dimensional site anatomy is the clinical question, practices use sectional imaging alongside intraoral views, in line with the justification requirements of IR(ME)R 2017.

Yes. The unit is designed for use with an intraoral digital X-ray imaging system, and the 0.2-second lower limit reaches the short exposure values direct digital sensors need. It also works with phosphor storage plates and standard intraoral film. Sensor hardware, sizing and imaging software are separate purchases — confirm the exact pairing at order so exposure protocols can be set at commissioning.

The specification gives 5–40 °C ambient temperature and relative humidity below 75%. That range covers normal UK surgery conditions without difficulty. For domiciliary and outreach work, be aware that an unheated care home corridor in winter or a vehicle boot in summer can sit outside those limits, so allow the unit to reach room temperature before use and store it inside the building overnight.

The moulded shell presents smooth external surfaces with few crevices, suited to wipe-down with the disinfectant products already used in your surgery decontamination protocol. Follow the manufacturer's cleaning instructions on agent compatibility, keep fluid away from the LCD panel and switch membrane, and treat the wireless remote as a separate item requiring its own between-patient wipe.

X-ray equipment carries physical security duties under IRR17, since unauthorised use is a foreseeable risk. The compact 330 × 310 × 230 mm packed envelope makes lockable cupboard storage straightforward. Agree a storage and key-control arrangement with your Radiation Protection Supervisor, and record it in your local rules alongside the charging routine.

Dental X-ray equipment is subject to routine quality assurance and periodic radiological testing under IRR17, alongside annual electro-mechanical inspection. UK service providers commonly apply an annual radiological testing interval to hand-carried units. A critical examination is required at installation. Your Radiation Protection Adviser sets the schedule for your registration. Medigear.uk can arrange service cover, planned maintenance and inspection scheduling with the supply package.

Warranty terms are set and issued by the seller or manufacturer, and typically run 12–24 months for this equipment class. Battery packs are frequently warranted on a shorter cycle than the tube head, and the wireless remote may be covered separately again. Confirm the exact terms, the parts covered and the consumable position at quotation. Medigear.uk can arrange extended service cover for UK customers.
