SOLD (UK) GWInstek GPD-4303S 4 channel programmable PSU
« on: October 11, 2017, 11:42:18 am »
Hidden deep down in the mountain of Tenma PSU boxes I found something actually quite nice...

GWInstek GPD-4303S - 4 channel (2 x 0-30V 3A, 1 x 0-5V 1A and 1 x 0-5V 3A or 5-10V 1A). All outputs are settable to 1mV/1mA resolution, the 30V channels can be switched between serial/parallel/independent with tracking in series. Good solid linear design with a smart fan so they don't sound like jets taking off.

It's a new unit direct from GW, supplied as a replacement for a unit that had a fault with channel 4.

Lovely quiet compact little thing, tempted to keep this but I'll never use it so it's got to find a better home...

List price £442+VAT, start this one at £250 plus shipping (£10 UK, £20 sensible EU countries, anywhere else please ask).

SOLD

Fair enough, I will post some pictures of the inside of the unit and share some experiances working with it. But I have lots of things asking my attention right now so have some patience. Until then, don't shoot the buyer ;D
(have missed out on previous sales from toploser, waited to long to decide)

Edit : While your'e waiting, I found this youtube clip about the 3 channel model from this series :

The four channel model has a  regulated channel 3, not stepped/fixed by a selector switch. So I expect it to be different hardware. I will test this on my unit and report it in a seperate post in the measurement and equipment section.
