Im using a second hand HLG-240H-36A LED Driver to power 2x QB132 v2’s Quantum boards which are 75w max each, so 150w together.

Trying to use the driver Adjustment screws for Voltage and Amps

The Io ADJ screw is doing nothing at all. And the Vo ADJ screw is changing amp current while the voltage stays the same, which is back to front?

Voltage won’t change from 247v on a (kill-a-watt meter) (in the UK)

Is the driver damaged or is it something else?

Is it safe for the amperage to be changing from the voltage adjustment?

Thank you :)

SOLVED:

Turned out that the Io adjust screw was not working until I turned the Vo adjust screw all the way up.

Discovered this while trying to brighten the light. The Vo adjust stopped raising the watts after about 90w even with screw turned all the way up. And then the Io adjust screw started working and now lets me have full control from that :)

Problem solved!

Hopefully this info might help others in the future!
