Product Description

Switching model LED Power Supply 12v 2a


DC input filter circuit principle:
① input filter circuit: C1, L1, C2 composed of double π-type filter network is mainly on the input power of electromagnetic noise and clutter signal to prevent interference to the power supply, but also to prevent the power itself generated high-frequency clutter on the grid interference. C3, C4 for the safety capacitor, L2, L3 for the differential mode inductance.
② R1, R2, R3, Z1, C6, Q1, Z2, R4, R5, Q2, RT1, C7 constitute the surge circuit. At the moment of starting, due to the existence of C6 Q2 is not conducting, the current circuit composed of RT1. When the voltage on C6 is charged to the Z1 regulator, Q2 turns on. If the C8 leakage or post-stage circuit short-circuit phenomenon, the instantaneous current in the RT1 generated on the voltage drop increases, Q1 conduction makes Q2 no gate voltage does not turn on, RT1 will be burned in a very short time to Protect the post-stage circuit.


For this item, followed are the Features:

1. Universal AC input/Full range

2. Protection: Short circult/Overload/Over Voltage

3. Cooling by free air convection

4. 100% full load burn-in test with 3-5 hours

5. No load power consumption < 0.5W

6. High efficiency, long life and high reliability

7. One year warranty

Please Note:

1. The testing condition for the parameter above is: 230VAC input, rated load, 25°C 70%Rh, Humidity.

2. Error, include the setting error, line stability and load stability.

3. Wave test: adopting "A12" double wire for 20MHZ, and 0.1uF capacitor short-circuit for interrupting.

4. Inlet Voltage Stability test: when is over load, the lowest voltage of inter is representative to the highest voltage.

5. Load stability test: the load is from 0% to 100%, others 60%.

6. C3.4 must be knocked down.


Applications:
