Introduction: EF series power inverter is adopted with advanced technology and high-frequency pulse width modulation control of the CPU design of new inverter technology, high reliability, protection-function, small waveform distortion, etc..
It can be converted to 110V AC or 220Vac 50Hz, voltage, frequency stability, with pure sine wave AC power. The product has a high conversion efficiency. (At full load conditions up to 85%). 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 achieve maintenance-free guarded function.
Application: Power plant, transformer substation, electricity system, rail system and so on.
Main Features:
1) Fully advanced DSP technology
2) Inverter Priority
3) With AC bypass function
4) Manual bypass fail-safe design to avoid wrong operation
5) Output and battery insulated completely
6) Full protection, input low,high voltage, output overload, short circuit
7) Intelligent Large LCD display and easy maintenance
8) Smart RS232 (SNMP CARD option), Dry contact;
9) Stable Parallel technology (N+1), common battery;
