For Sale Two UCD400HGHXR and their linear PSU

[silverprout]

Hello, 200€ for everything, used only a few for a test but the 400W are useless for me.

Hi,

I am interested to buy. Where are you located (country)?

hello, i'm from France, i can send them everywhere.

You should not be anxious about the samwha HC, i've got them on a amp that opreate every day since many years and they are reliable and exceed the manufacturer specifications, they can deliver more than 25A continuously for each amp and the UCD400 modules are shutting down at 20A.

Is there anyone here that can say how i've succeed to go over 20V on a 1.5 ohm resistor with these modules ?
400/20=20V

The 20A is the UCD400HG Hxr current limit. You likely were not there for very long.

The modules are blinking slowly when are at their current limit, i've tested them just under the limit until the blue heat spreader surface have reached 45°C, just to be sure that they are fully functionnal before selling them, the dummy load surface was at 70°C.
I think that my resistor is not measuring exactly 1.5 ohm and i don't have a milliohmmeter neither a 20A capable multimerter to confirm my theory 😢
