Mean Well HLG Driver Spreadsheets

Hi all,

It can be a pain in the ass having to sort through a bunch of data sheets to find what you’re looking for, so I’ve compiled all the relevant specs for Mean Well Constant Current and Constant Voltage HLG series drivers into a couple spread sheets. I’ve also pulled data from their test reports – you’ll see info from the specification sheet marked “SPEC” and then info from Mean Well’s testing, marked “REPORT”. You’ll notice that usually these drivers are capable of doing a little more than they’re rated for, however this is often for the “A” type driver, on which you are able to adjust the voltage or current higher than you can on the “B” type.

 

Here is the constant current sheet.

 

Here is the constant voltage sheet.

Check out the parallel strip build tool below!
