Independent power supply for constant voltage LED

lamp

Special design screw terminal for field connection

Mini DC socket at the secondary side for quick

connection

Class II protection against electric shock from direct

and indirect contact

SELV output

Open circuit，short circuit，over load and over

temperature protection

Auto restart after fault conditions removal

No load power consumption≤0.3W

Efficiency ≥83%（AC230V,full load）

This type of power supply is an exclusively designed

stabilized power supply for LED lamp. With constant

voltage (CV) technology, it is suitable for constant voltage

lamps (12/24V DC) connected in parallels. As an advan-

tage of constant voltage (CV) technology, a switch can

be installed between secondary side and lamps.

The built-in protection circuit will shut down the power

supply in case of such faults as: open circuit, short circuit,

over load or over temperature. The power supply will

restart automatically after fault correction.
