- Features
Product introduction:
The inverter power supply module adopts the latest power technology and digital DSP control, it is designed for new energy. The front stage adopts industry-leading three-phase active power factor correction (APFC) technology, and the latter stage adopts three-level full-bridge resonant soft switching technology. The input voltage range is wide, the total harmonic current is less than 3%, and the input power factor is up to 0.99. Efficient, high power density, high reliability. It adopts forced air cooling to dissipate heat, which occupies a small space and easy to assemble!
Features:
◆ Ultra-wide output voltage range: 200V~500Vdc;
