Digatron EW 20-70 "Electronic Resistor" Teardown
« on: February 06, 2020, 04:05:00 pm »
Was looking for an affordable high power capable electronic load. Found this beast for pretty cheap  :-+

20A / 70V / ~1.4kW
Unfortunatly zero decumentation. And the PCB is potted. Pitty.

Very interesting E-load. How loud is it?

Not to bad. It has two PAPST fans in there. Can't really tell the model because of the fine mesh cover.
Slightly less noisy than my Noctua AF14 3000, perhaps 40-45db. Audible but I have headphones on anyway  ^-^
