Introduction: EF series 3phase industrial power inverter is adopted with advanced technology and high-frequency pulse width modulation control of the CPU design of new inverter technology, super high reliability, protection-function, small waveform distortion, etc..
It can be converted to 110V AC or 220Vac 50/60Hz, voltage, frequency stability, with pure sine wave AC power. The product has a high conversion efficiency. (up to 85%@ 100% load). As well as a strong non-linear load drive capability. The input voltage, current and output voltage and current monitoring for detection, in order to achie ve maintenance-free guarded function.
Application: Power plant, transformer substation, electricity system, rail system, oil, gas, harsh environment etc.
Main Features:
- Fully advanced DSP technology
- 7inch large colorful touch screen with high resolution
- Inverter Priority
- With AC bypass function
- Manual bypass fail-safe design to avoid wrong operation
- Output and battery insulated completely
