Korad KWR102 power supply

(1/4) > >>

knudch:
I have just got this one on my table


30V - 30A, max 300W so called wideband PSU
Seams ok for the price (275 euro incl shipping)
RS232/RS485/LAN communication
First test is ok...stable and no stranges behavior
There are 2 fans inside, but not much noise from them under load, no load, no noise at all.
Documentation is some what "simple" 15 pages manual...leaves a number of questions.
Accessories: Cables, Mains, USB, RS232 DB9, heavy test leads, software CD.
Under load there is a humming from the enclosure......in quiet places and for long time ...annoying   
UI you need to get used to !
But every thing is working so far.

Was actually looking at something "bigger" like Siglent SPS5042X 40V/60A/720W or ITECH IT6723C 32V/110A/850W
But I considered that those cases where I need such current is limited to 12V/230V power inverter testing and for that I bought a brand new server supply 13,5V/100A for 50euro.
Of course are siglent/itech properly another quality, but also another price level.

knudch:
Have tested the software which came with the unit
Nothing fancy but ok for testing remote operation.
Can do simple list based jobs.

Tested setting and read-back accuracy, is ok, within spec's as far I can check.

The plugs on the front shall be un-sharped....when you plug in a test lead it's sound not nice and I can see a bit of metal parts.
Can be un-sharped with a drill of fitting size.

Inside it is compact but looks ok, big components are glued to prevent getting loose due to vibration

Generally it meets my expectations in relation to price/performance

radiolistener:
I'm not sure, why it has "max 10 A" label near output terminals? Because PSU is marked as 30 V / 30 A

knudch:
Max 10A on front terminals, rear terminals 30A
Typical for PSU with more than 10A
Front terminals are "normal" plug/binding post
Rear is screw terminals
