Constant Current LED Power Supply
SLT20-500IL-UN(for independent use)
SLT20-500IB-UN(for built-in use )
Product description
This type of compact constant current power supply with
110-277Vac input voltage has very high efficiency and low
power loss.
Designed with high power factor and low output ripple, it can
be used either built-in or independently. The output current
can be set by the DIP switch, and the output current can be
switched every 50mA from 150mA to 500mA.
It conforms to SELV standard and the built-in protection circuit
will shut down the converter in case of such faults as: open
( or optional )
pending
circuit, short circuit, over load, over temperature. The power
supply will restart automatically after fault correction.
