Description
A compact 20W constant current switching power module suitable for driving up to 15 high power LEDs (Vf = 3.6V).
The output current is fixed at 350mA or 700mA. Active power factor correction is standard.
This series features both screw terminal and socket output connections. The socket connecter avoids the possibility of
miswiring and damaging the LED load if the LEDs are preassembled into a wiring harness or lamp fitting.
