SPFC series frequency conversion power supply products are specially designed and manufactured for voltage conversion, frequency conversion testing and power supply of import and export electrical products
SPFC series program-controlled AC variable frequency power supply, with DSP/FPGA processor as the core, adopts PWM method, sinusoidal pulse width modulation and other technologies, the single machine capacity is 500VA-1000KVA, the output can simulate different voltages and frequencies around the world, and can meet the requirements of various industries. with load demand. The power supply is output by an isolation transformer, which is safe and reliable and can increase the stability of the whole machine. It has the characteristics of strong load adaptability, good output waveform quality, easy operation, small size and light weight. It has perfect short circuit, overcurrent, overvoltage and overheating. and other protection functions to ensure the reliable operation of the power supply.
SPFC series frequency conversion power supply products are specially designed and manufactured for voltage conversion, frequency conversion testing and power supply of import and export electrical products. They can provide standard grid voltage and frequency all over the world. The digital is adjustable, the waveform is stable and pure, and the grid interference is eliminated. This series is integrated with high-precision voltage, current, and frequency display meters, with high performance-price ratio. It adopts Siemens or Japan's Mitsubishi original high-power IGBT module design to reduce circuit complexity, improve product stability, and reduce power loss. So that the single-machine capacity continues to rise. In addition, this series of power supplies produced by our company adopts a number of ultra-isolation transformers, which completely isolate the mains and the load to increase the function of the whole machine.
