Bridge
Type Application Circuit
( 20mA each LED String)
Number of LED's that can be connected is determined by:
LEDs=(Vdc-Vak)/LED VF
Example:
Vac=110V,CLD Vak=45V,LED VF=3.5V@20mA
Using our P/N:MB6S bridge for whole wave rectifier
After rectifier, Output Vdc=150V
(150Vdc-45Vdc)/3.5Vdc=30 LEDs in series.
