Product description
This ty
This type of power supply is an exclusively designed
stabiliz
stabilized power supply for LED lamp. With constant
olta
voltage (CV) technology, it is suitable for constant voltage
amps
lamps (12/24V DC) connected in parallels. As an advan-
tage
tage of constant voltage (CV) technology, a switch can
e inst
be installed between secondary side and lamps.
The b
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.
Characteristics:
•
Independent power supply for constant voltage LED
lamp
•
Special design screw terminal for field 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
•
Quiet design,working noise is less than 20dB
•
No load power consumption≤0.3W
•
Efficiency ≥83%（AC230V,full load）

1. Tolerance:includes set up tolerance, line regulation and load regulation.
2. Tested at full load,230Vac.Refer to"Power Factor" and "EFFICIENT"curve graphs.
3. Calculate the model’s average efficiency for each test voltage by testing at 100%, 75%, 50%, and 25% of
rated current and then computing the simple arithmetic erage of these four values.
4. All parameters NOT specially mentioned are measured at nominal voltage input, rated load and 25 of
ambient temperature.
5. The power supply is considered as a component that will be operated in combination with final equipment.
Since EMC performance will be affected by the complete installation, the final equipment manufacturers must
re-qualify EMC Directive on the complete installation again.
