I can't seem to find the info on the front power switch modification mentioned in the manual.
This would allow turning on the backend supply with the front panel power switch.
Has anyone successfully implemented?
Yes, it is implemented in my 3 assembled power supplies (RD6006, RD6006P, RD6012).
Have as well RD6018, but it is just a disassembled module.
My thought was to use j2.4 (20ma max) to drive a fet which will drive a relay (250v/20a) to turn on the back end supply.
No problem. Just don't forget to add pull-down resistor to the Gate/Base of the transistor.
Pin j2.4 can have a 3 states: Z and L - disabled, H - enabled.
Would have to add a 12v low power wallwort to the mix and connect through a diode to the rd6018 too. Would use same 12v to fet for relay.
I made a powering only for controller part.
By the way, there is a 5V relay, then a 5V DC-DC converter will not be needed.
Here is schematics
Here you can see my assembled RD6006P, with power switch...
Using only ready modules...
1. 12V Power supply MW-10-12 (fake MeanWell, based on ST VIPer22A)
2.
Relay module YYG-2 (12V)3.
Plastic case for relay module 70*45*29mm (SZOMK AK-S-118)4.
5V DC-DC ConverterP.S. Note, there are 5V relay module and 5V Power Supply (MW-10-5)
