DPS5005 power supply, remote control using python serial port modbus

Just a short one.
I bought one of these things.
It can do 50 volt 5 Amp, I have not looked at the quality of the output (noise, overshoot all unknown to me)  but should be alright to control a lamp, a battery or a strip of LED's is my guess.


You can easily control the current and voltage output using a serial port. (a usb-serial-rs485 was provided)

I seems to talk modbus protocol.

To change the baud rate and modbus-slave-address, keep POWER button pressed during power on, this will enter you into the configuration menu.
