Received the
DL24MP-HSpec same as DL24: 200V, 20A, 150W. But, has four times the transistors.
Some reviewers received IRFP260N (blacktopped), I received
38N30 (300V, 38A, Vgs 30V) that appear to be recovered parts. Decent FETs if they are real.
Fan is loud, turns on when you turn on the output.
At 60W heatsink is ~42C
At 80W heatsink is ~60C
There are also some 0.25R 6W resistors on the side of the heatsink that get hot as well.
This is just using their included NTC probe, I'm sure the FETS are much hotter than the heatsink temp. So maybe 100W max that I'd want to run this at?
Notes:
- If you have the current resolution set to 1mA (actually shows as 100uA), the maximum CC is 2A. If you go above that it will shut the output off. The other option is 10mA resolution which allows the full output current.
- Fan temp sensor appears to be the NTC beside the heatsink, add some thermal compound to couple this better to the heatsink. Its still a terrible representation of the temperature though, shows about 20C lower than actual.
