What happens right here with rb 153.
1 - When the power surge it hangs even when plugged into nobreak protected, I have to disconnect and reconnect it to her back.
2 - it always burns a component of the input source (Q8-D5N20) always have to change this component because it burns.
3 - I use it here source 12 volts and 1.5 nd nd 3.5 Source 18volts always right on the input source, never puts the door.
I wonder if you can help me solve this problem.
Grateful for the time being!
