Xkg-240-h-ab and 2 qb288

[jumby_growr]

The constant power part is throwing me. 2 qb288 and 1 xlg-240-h-ab to drive them. Individual heatsink for each board and a potentiometer for dimming. Series or parallel? Guessing parallel but how to limit voltage?

Thanks for the help

Parallel Wired...

• The Driver’s internal circuits will automatically adjust the Voltage when the Vf is within the CC region, 27 - 56 Vdc.

• The Dimmer pot adjusts the Watts / Current and the Voltage output is automatically maintained.

You’re welcome.

So just plug and play? Hook the boards up in parallel and done?

Yes, for 240 Watt output...

The Io adj. internal pot can be set for 120 - 240 Watts max and the external dimmer pot can be manually adjusted from ~ 10 - 100%, 12 - 240 Watts respective of the Io internal pot (12 - 24 Watt min, respectively).

Got it. I appreciate it!
