Looking for docs => Rohde&Schwarz NGRE 40/30 Power Supply DC 0-40V 0-30A

<< < (4/4)

9aplus:
The brightness of LEDs is about the same, like the near bulbs.
Around 8 mA AC going through. So far no burnout, let's see ;)

Considering to add some wheels on the short open plywood vertical box,
sized to tight fit the PS box from behind.
That also may make the cooling stream noise bit lower.

9aplus:
UPDATE II

It seems that my units are custom made.
Both going up to 50 V DC (under load) instead of 40 V DC as written on front.

One unit is responding well on the load in regards of noise and cooling speed. The second
is going almost full speed from the turn ON.
Must find that PTC/NTC whatever is somewhere in regulation chain.
