I have a 230VAC, 12VDC SMPS for LED lighting.By mistake, my technician connected the 230VAC supply on the 12VDC output terminal of the SMPS and LED light on the 230VAC input terminal as the Terminal indicating stickers were stuck wrongly by the manufacturer. The input MCB breaker tripped. He than corrected the SMPS connection but the LEDs are not working now!!What is the worst that can happen in this case.
