Does anyone has experience with Inventronics drivers? I got 3 QB96 hooked up parallel and Im only getting 53v and 4.4amps max. When I put the driver to a single QB I get 56v and 4.3amps max. I have a dc meter connected to a shunt. The driver was used of ebay, I bought 3 of the same driver for $12 a piece shipped. All 3 drivers has the same value output. Here is the link to the datasheet https://www.inventronics-co.com/wp-content/uploads/2017/12/DS-EUC-320SxxxDTST-Rev.D.pdf

Did I hooked up the lights correctly based on what the driver is pushing out?

Values wise looks ok to me. When you put all the boards in parallell each board sees 4.5amps /3 boards = 1.5amps per board. With a voltage of 52.95V

seems to be following HLGs chart pretty well.

Thank you for that explanation. So Im going to get 3 more drivers and run them independently. Cheaper than buy 2 600w.

To the best of my understanding that driver should do 4.9 amps output. Sometimes the dimmer doesnt allow for full range dimming, you can try to see if output changes if you disconnect the dimmer.
