Power supply output voltage fault
I bought a LED driver:
Output: DC30-57v / 600mA (constant)
I connected it to a led strip, they flashed several times then switched off (i suspect they died, so i check the LED Driver Failure Analysis and Maintenance to detect), then took the multimeter and measured the Output voltage, and it was around 74V, but failed.
I suspect this is what killed the leds.
My question is: am I missing something ? This power supply is supposed to output max 57V. Why does it show 74?
Is the power supply faulty? Or did I measure it wrong?
