My "UNIQ" 2-axis DRO display has failed. The vendor says the power

replacement "UNIQ" for $295 or a "JENIX" display for $200.

I have asked them to return the unit. Does anyone know anything about
these? Would the PS be fairly easy to repair? I'll know more when I
get it back and apart.

Power: DC 5V (15%) 80 MA.

Does that use a wall wart, Tom?

80mA (400mW) doesn't sound like nearly enough. Maybe that's the power
_output_ for the scales.

The "Sino" lathe DRO I have contains a small more-or-less open-frame
5VDC switching supply, just 5V out. about 140 x 60 x 40mm. I would
expect yours is quite similar. Similar 25VA units are around $20 qty
1.


(RS-232 for the last decade or two generally used +/-V generated from
5V or 3V using a MAX232 or similar chip).

Imagine if it only needs 5v, I have plenty of old computer PS's, any
reason I couldn't cob something external using one of those?
