The Visionstar TR-102A is the only unit in this range whose datasheet an installing electrician could work from without asking a single question. That is not a small distinction. Across this category most manufacturers publish a lamp wattage and leave everything else to be discovered on the day, and a practice booking an electrician for a fixed-price installation has no way to brief them properly.

Here the figures are given. Input voltage is 110V/220V AC at 50–60 Hz. Engine power is 55 W at 220 V, the light 16 W, and no-load draw 1 W. Protection is a 5 A 250 V fuse on a 10 A 250 V main wire. A 2 kV pressure test result is stated, which is the dielectric strength verification underlying the electrical safety case. Working mode is S1 — continuous duty, meaning the unit is rated to run indefinitely at load rather than on a duty cycle. The operating envelope is −10 °C to +40 °C at under 90% relative humidity.

Taken together those figures let a practice specify the circuit, brief the electrician, satisfy a compliance file and know the unit will tolerate an unheated room out of hours. None of that is possible from a datasheet giving only a lamp rating.

The mechanical specification is equally granular. The chair adjusts 460 to 600 mm — the lowest minimum seat height in this range — rotates ±60°, and the backrest sets between 90° and 135° of obliquity rather than a single stated angle. A pillow adjusts up to 150 mm, which no other unit here offers: head position matters at a slit lamp and a fixed headrest suits one neck length.

Two table sizes are given, 840 × 405 mm and 670 × 405 mm, with 90° rotation and 330 mm of sliding travel. The swing arm moves ±30°. Overall the unit measures 1560 × 1000 × 2000 mm at 175 kg.

One figure should be read carefully rather than skimmed: chair loading is 150 kg, materially lower than the 200–250 kg stated elsewhere in this range. Medigear.uk supplies the TR-102A with pre-despatch functional inspection and documentation review.

Practices commissioning a fit-out benefit before the unit is even delivered. An installation is quoted and booked in advance, and an electrician asked to fit equipment needs the supply, the protection rating and the wire rating to specify a circuit and price the work. Given only a lamp wattage — which is all most units in this category publish — they either estimate or attend twice. A datasheet stating 110V/220V AC, 55 W engine power, a 5 A 250 V fuse and a 10 A 250 V main wire lets the brief be written once and correctly.

Compliance files are served by the same detail. A 2 kV pressure test result and an S1 continuous duty classification are the kind of figures an equipment register or a procurement review asks for, and having them published rather than requested is a practical saving for anyone maintaining that documentation.

Rooms with variable conditions suit the stated envelope. Operation from −10 °C to +40 °C at under 90% humidity covers an unheated consulting room overnight and a poorly ventilated one in August — circumstances that arise in converted premises far more often than equipment specifications acknowledge.

Patient positioning gains from two features unique in this range. The pillow adjusts up to 150 mm, so head position is set to the patient rather than fixed at manufacture, which matters during sustained slit lamp work. And the backrest is specified as a 90° to 135° obliquity range rather than a single maximum, so the upright end is genuinely upright for patients who cannot recline.

One figure belongs squarely in the decision rather than a footnote: chair loading is 150 kg, materially below the 200–250 kg stated elsewhere in this range. That constrains the accessible caseload, and it should be weighed openly against the electrical and positioning advantages.

An electrician can quote from it

Supply, engine power, fuse rating, wire rating and duty classification are all published, so a circuit can be specified and an installation priced before anyone attends. No other unit in this range supports that.

A compliance file that fills itself

A 2 kV pressure test result and an S1 continuous duty rating are exactly what an equipment register or procurement review asks for, and they are printed rather than requested.

Rated for rooms that are not always heated

An operating envelope of −10 °C to +40 °C at under 90% humidity covers an unheated room overnight and a stuffy one in summer — conditions converted premises produce regularly.

Continuous duty, stated

S1 means the unit is designed to run at load indefinitely rather than on a cycle. For equipment used across a full clinical day that is the right classification, and elsewhere in this range the question simply goes unanswered.

The head position is set to the patient

A pillow adjusting up to 150 mm sets head height to the person rather than fixing it at manufacture, which matters during sustained slit lamp work where a fixed headrest suits one neck length.

Backrest given as a range, not a maximum

Ninety to 135 degrees of obliquity tells you the upright end is genuinely upright as well as how far it reclines — useful for patients who cannot lean back comfortably.

The lowest seat in the range

At 460 mm the chair descends below standard wheelchair seat height, making transfer a lateral move rather than a lift.

The right fuse can be stocked in advance

A published 5 A 250 V rating means a spare sits in the cupboard rather than being sourced mid-breakdown.

Full electrical specification

Input voltage 110V/220V AC at 50–60 Hz, engine power 55 W at 220 V, light 16 W, no-load power 1 W — published in full rather than as a lamp rating alone.

5 A 250 V fuse and 10 A 250 V main wire

Protection and wiring ratings are both stated, allowing a circuit to be specified and a spare fuse stocked correctly.

S1 continuous duty rating

The unit is classified for continuous operation at load rather than a limited duty cycle.

2 kV pressure test

A dielectric strength verification result is published, underlying the electrical safety case.

Operating envelope −10 °C to +40 °C

The unit is rated across a wide temperature range at under 90% relative humidity.

Adjustable pillow, up to 150 mm

The pillow raises up to 150 mm, setting head position to the patient rather than fixing it — unique in this range.

Backrest obliquity 90°–135°

The backrest is specified as a range between fully upright and 45° past it, rather than as a single maximum angle.

Chair height 460–600 mm

The chair descends to 460 mm, the lowest minimum in this range and below standard wheelchair seat height.

Chair rotation ±60°

The chair rotates 60° either side of centre, a stated angle rather than an unquantified rotation.

Two table sizes

Table sizes of 840 × 405 mm and 670 × 405 mm are listed; confirm at order whether this indicates a two-part table or a size option.

90° table rotation and 330 mm slide

The table rotates through 90° and slides 330 mm, positioning instruments without lifting them.

Swing arm ±30°

The swing arm moves 30° either side of centre.

1560 × 1000 × 2000 mm at 175 kg

The unit measures 1560 mm by 1000 mm on plan, standing 2000 mm high and weighing 175 kg.

The Visionstar TR-102A is the only unit in this range an installing electrician could quote from without asking a question. Input voltage, engine power, light load, no-load draw, a 5 A fuse on a 10 A wire, a 2 kV pressure test result, S1 continuous duty and an operating envelope from −10 °C to +40 °C are all published — which lets a circuit be specified, an installation priced, a compliance file completed and a spare fuse stocked, none of which is possible from a datasheet giving only a lamp wattage. The mechanical detail matches: a chair descending to 460 mm, the lowest here and below wheelchair seat height; ±60° rotation; a backrest given as a 90° to 135° range rather than a single angle; and a pillow adjusting up to 150 mm, unique in this range and genuinely useful during sustained slit lamp work. One figure needs weighing openly rather than skimming: chair loading is 150 kg, materially below the 200–250 kg stated by several siblings, which constrains the accessible caseload and belongs in the same decision as the electrical advantages.

FAQ

Frequently Asked Questions

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

Because an installation is quoted and booked before anyone sees the equipment. An electrician asked to fit a unit needs the supply, the protection rating and the wire rating to specify a circuit and price the job. Given only a lamp wattage they either guess or attend twice. This datasheet lets the brief be written correctly the first time.

Continuous duty. An S1 rating means the unit is designed to run at load indefinitely rather than for a limited period followed by cooling. For equipment operated throughout a clinical day that is the appropriate classification, and its absence elsewhere leaves the question open.

A dielectric strength verification — the insulation is tested against 2 kV to confirm it withstands well beyond working voltage. It underlies the electrical safety case, and seeing the figure published rather than merely implied is unusual in this category.

Because rooms are not always heated. A unit rated from −10 °C to +40 °C and under 90% humidity will tolerate an unheated consulting room overnight or a poorly ventilated one in summer. Equipment without a stated envelope may or may not; nobody finds out until something fails.

150 kg, and this deserves a straight answer: it is materially lower than the 200–250 kg stated by several other units in this range. For a practice assessing accessibility that is a real constraint rather than a technicality, and it should be weighed against the electrical advantages this unit offers.

460 mm, which is the lowest minimum in this range. That is below standard wheelchair seat height, so transfer is a lateral move rather than a lift — a genuine access benefit, though it sits alongside the lower loading figure and both belong in the same decision.

It raises up to 150 mm to set head position. That matters at a slit lamp and during any sustained instrument work, because a fixed headrest suits one neck length and asks everyone else to adapt. No other unit in this range specifies an adjustable one.

The backrest sets anywhere between fully upright and 45° past it, expressed as a range rather than a single maximum angle. Being given both ends tells you the upright position is genuinely upright — useful for patients who cannot recline comfortably — as well as how far back it goes.

The datasheet gives 840 × 405 mm and 670 × 405 mm, which indicates either a two-part table or a size option. Confirm which at order, since it affects both the working area and how the 90° rotation and 330 mm slide behave.

The electrical side is fully specified; the physical side is not. At 175 kg confirm floor loading, delivery access and positioning labour, and whether installation is included in the quotation.

An ophthalmic examination unit is generally classified as Class I under the UK Medical Devices Regulations 2002, or higher where configuration dictates. Manufacturer CE marking is noted where it appears in the product literature; Medigear.uk confirms CE marking, the declaration of conformity and current UKCA status against the shipping batch at quotation rather than asserting it in advance.

Upholstery cleaning with an approved agent, periodic inspection of the chair lift, rotation, backrest and pillow adjustment for developing play, and fuse replacement to the stated 5 A 250 V rating. Having the fuse specification published means a spare can be stocked correctly rather than sourced during a breakdown. Typical warranty is 12 to 24 months against manufacturing defect, confirmed at quotation.
