Do the RPK LED Drivers have a Minimum Load Requirement?

Let us know!

Yes.  Typically 25% minimum load (+/-).

These drivers are sized by load/Forward Voltage, therefore as an example, Model RPK-LV-40 has a Maximum load of 40 VDC, which includes the sum of all LEDs and all voltage drop in that circuit.

Minimum Load would be 25% x 40 VDC = 10 VDC , which is typically 3-4 LEDs..  For loads outside this range (10-40VDC), select a different driver.
