Variable Frequency Power Supply

The variable frequency power supply can not only imitate the grid index in many countries in the world, but also can supply the pure, reliable, low harmonic wave distortion, high stability sine wave power output for export electronics manufactures in the application of designing, developing, testing and producing. The characteristics of ideal AC power supply are frequency stable, voltage stable, zero resistance; voltage waveform is pure sine wave (no distortion). The variable frequency power supply is very close to the ideal AC power supply. So, more and more developed countries adopt the variable frequency power supply as the standard power supply, to provide the best condition for electric equipments and objectively access their technical performance.

SC/BP series variable power supply has the microprocessor core, and make as the way of PWW. It uses the active component IGBT module design, adopts the technologies such as, digital divide frequency, D/A converter, instantaneous value feedback, sine pulse width modulation and so on. The unit capacity can reach 2000KVA, so that isolate transformer output to improve the stability of the machine and make sure the power supply can operate reliably.

Type:

Linear amplifier type and PWM switch type

Characteristics:

1. Strong Overload: It has the function of 300% overload ability and can meet start-up requirements of impact load.
2. Slow Start Function: Cut down the start-up current of transformer, compressor and motor. It can realize the slow start-up of load, reduce the capacity requirement of power supply.(Optional)
3. Output Range Width: Frequency option: 40~70Hz, 50Hz, 60Hz, 100Hz, 120Hz, 240Hz, 400Hz. The minimal frequency is 5 Hz, and the maximum frequency is 1500Hz. The maximum voltage is 100V, the maximum power of single machine is 2000KVA, and parallel machines can realize bigger power conversion.
4. Low Harmonic Wave Interference: Output sine waveform, full load distortion is less than 1.5%, low radiation interference, and will not affect the use of nearby equipments.
5. Strong Protection: It has the protection of over current, over voltage, short circuit, and over temperature. It also has the self-diagnosis protection and alarm device.
6. Fast Transient Response: In the process of load 0%~100% or 100%~0%, the output voltage wave can recover in one cycle.
