Power Led Drivers

Technical Specifications of 21CC LED DRIVER:-

Product Type: APT21CC is a constant current driver (as required for Power LEDs) which is used for driving upto 21 PowerLEDs of 1Watt.

PRODUCT CODE: APT21CC

Input Voltage Range: 90VAC to 300VAC
Frequency: 47Hz to 53Hz
Output Voltage Rating: 75V @350mA (Current limit).
The current remains constant @350mA,for a O/P voltage variation between 35V to 75V,and so this can be used to drive 15 to 21 Power LEDs of 1W in series.
Efficiency: >80% (at full load at 220VAC)
Operating Temp. Range: 0o C to 50oC.
Current Regulation: Less than 1% over entire line variation, load variation.
Size: 160mm*85mm*35mm

Protections:

Input over voltage cut-off for Vac>300VAC.
Surge protection at input and output.
Latched output over voltage protection at 90V(approx.)
Latched output over current protection >425mA.
Latched output short circuit protection.
Over temperature protection.

Visual Indications: Mains ON: Yellow LED
Output OK: Green LED
Fault: Red LED
