FAQ
What is a constant voltage power supply?
Answers: Most common constant voltage drivers (or Power Supplies) are 12VDC or 24VDC. An LED light that is rated for constant voltage usually specifies the amount of input voltage it needs to operate correctly. A constant voltage power supply receives standard line voltage (120-277VAC).
