BG183351204 23/07/2020

Really good value for the money. Want to use it as part of a double power supply. Tested the voltage regulation , which is working well ; but the input voltage must be higher than the output voltage (only voltage reduction by the unit). - input voltage galvanically connected to the - output voltage via a current sensing resistor of 40 mohm The ring-coil is working as an inductor and not as a transformer. Current regulation is active at around 0,5 Amp. and higher (not tested beyond 1 Amp.)
