CL-3000-300 3KW 300V DC PFC Power Supply

CL-3000-300 3KW 300V DC PFC Power Supply

This is a DC power supply, the model number is CL-3000-300. It is Small size, light weight, small ripple, high efficiency, high reliability With active PFC power factor correction. INPUT AC110V-169V 25-16A, OUTPUT DC 300V 8.3A.

Industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment instrumentation, medical, and so on. 

Role of active PFC:.

1. Improve the power factor, so that the input AC voltage phase and current phase synchronization, the power factor is close to 1, so that the switching power supply on the grid utilization rate is close to 100%

2. Reduce harmonics (THD value), active PFC circuit can greatly reduce the harmonic interference of the switching power supply itself, reduce the pollution of the power grid, the power factor is close to 1, so that the utilization of the switching power supply to the power grid is close to 100%.

3. Wide voltage input, can make the high-power switching power supply like flyback small power supply as wide voltage 90-265V input (no need to 110 and 220V voltage switching)

4. Active PFC itself is a boost-type boost power supply, the first input AC100-240V voltage boost to DC400V and then sent to the PWM circuit, as opposed to AC220V directly rectified and filtered DC310V, under the same power, the voltage is high, the switching current flowing through the PWM circuit reduces the switching current, switching tube heat will be reduced!
