Visionstar TR-700A

Instrument-dense positions benefit most directly, and the benefit is about cabling rather than clinical performance. Ophthalmic instruments run on a range of low voltages, and the usual setup puts a separate transformer or adaptor behind each one—occupying sockets, filling the floor beside the chair with power bricks, and leaving a cable run to manage whenever anything moves. Seven selectable taps and a charging output replace that with a single supply from the column.

Older premises gain most from the socket reduction. A consulting room in a converted building frequently has fewer outlets than a modern fit-out assumes, and adding them means containment, chasing or trunking. Powering instruments from the unit sidesteps that entirely.

Floor safety improves as a by-product. Fewer adaptors beside the chair means fewer cables in the strip where patients approach, transfer and sit.

Continuity is the quieter benefit: an instrument whose own adaptor fails can run from the unit while a replacement is sourced, rather than standing idle for a week.

The four individually specified arms suit a position carrying a phoropter, an auto keratometer, a projector and a slit lamp together — with per-arm load ratings of 30, 30, 10 and 50 kg published so an instrument can be matched to a mount before ordering rather than after.

Three things belong firmly in the decision. Instrument compatibility must be confirmed case by case — voltage alone does not establish it, since current capacity, connector type and AC-versus-DC expectation all matter. The published envelope of 1884 × 1316 × 1663 mm excludes the tabletop and lighting, so the installed footprint is larger than stated.

The column powers the instruments

Seven switched AC taps from 2.5 to 12 volts plus 5V DC charging — the only unit in this range that supplies its instruments rather than merely carrying them.

Fewer sockets needed

A converted consulting room rarely has the outlets a modern fit-out assumes, and adding them means containment or chasing. Powering from the unit avoids that work entirely.

The floor beside the chair clears

Power bricks and their cables occupy the strip where patients approach, transfer and sit. Removing them is a safety gain as well as a tidiness one.

An instrument keeps working when its adaptor fails

A failed transformer normally means a device stands idle until a replacement arrives. Running it from the unit keeps it in service.

Four arms, four published load ratings

Thirty, 30, 10 and 50 kilograms across phoropter, keratometer, projector and slit lamp arms — granularity that lets an instrument be matched to a mount before ordering.

A slit lamp arm rated properly

Fifty kilograms with table movement within an 824 mm radius semicircle and 716–1016 mm of height, for the heaviest instrument in the room.

Seat detail to match

Lift 568–708 mm, headrest adjustment 250 mm, seat rotation 0–270°, backrest 80°–180° and a footrest from 88 mm above ground.

Seven switched AC outputs

Output voltage is published at 2.5, 3.5, 4.5, 5.5, 6.5, 7.5 and 12 volts AC, alongside mains passthrough at 100–120V and 200–240V.

5V DC charging output

A dedicated charging supply is provided; available current is not stated.

Phoropter swing arm

Rated 30 kg, swing ±30°, rotary arm 0–300°, up and down travel 900–1500 mm.

Auto keratometer arm

Rated 30 kg, swing ±40°, first rotary joint 360°, second rotary joint 0–300°, tray rotating 360°, travel 780–1380 mm.

Projector arm

Rated 10 kg, rotary arm 360°, tray 360°, travel 1030–1530 mm.

Slit lamp arm

Rated 50 kg, table 350 × 200 × 25 mm customisable to 700 × 400 × 40 mm, movement within an 824 mm radius semicircle, height 716–1016 mm, table board rotating 360°.

Seat parameters

Lift 568–708 mm, headrest adjustment 250 mm, seat rotation 0–270°, footrest from 88 mm above ground, backrest 80°–180°, maximum load 150 kg.

295 kg weight

The heaviest unit in this catalogue by 85 kg.

1884 × 1316 × 1663 mm

The published envelope excludes the table top and lighting; the installed footprint is larger.

Full electrical schedule

Input 100–120V and 200–240V AC at 50/60 Hz, engine power 28V 1.5A DC, light 5/16W 24V DC, 5 A 130/250 V fuse, 10 A 120/250 V main wire, 1 W no-load draw, 2 kV pressure test, S1 continuous duty, −10 °C to +40 °C.

The Visionstar TR-700A publishes something no other unit in this range does: an output voltage list. Alongside mains passthrough it supplies switched low-voltage AC at seven settings from 2.5 to 12 volts, plus 5V DC for charging — which makes it furniture instruments plug into rather than furniture they sit on. The practical consequence is cabling: ophthalmic instruments run on a spread of low voltages, and the usual arrangement puts a transformer behind each one, occupying sockets and filling the floor beside the chair with power bricks. One supply replaces that, which matters most in older premises where outlets are scarce and adding them means chasing or containment. The mechanical detail is equally unusual, with four arms individually specified and load-rated at 30, 30, 10 and 50 kg, so an instrument can be matched to a mount before ordering. Three things must be settled first: instrument compatibility case by case, since voltage alone does not establish it; the installed footprint, since the published envelope excludes the table top and lighting; and delivery, since at 295 kg this is the heaviest unit in the catalogue by 85 kg.
