ENGELEC
EESNB 15KW
EESNB 15KW Off-Grid Power Frequency Inverter Three phase
Features
◆ Complete isolation-type inverter technology, noiseless output.
◆ Adoption of advanced SPWM technology, pure sine wave output.
◆ Dynamic current loop control technology to ensure inverter reliable operation.
◆ Wide DC input voltage range.
◆ Excellent EMC design.
◆ Low output harmonic distortion (THD≤3%).
◆ LED indicators for input voltage range, load power range, normal output & failure state.
◆ Optional energy saving mode.
◆ Extensive protections: reverse polarity, short-circuit, overload, under/over input voltage over-temperature, and inverter’s inner fault identification protections.
◆ Wide working temperature range (industrial level).
◆ Continuous operation at full power.
Application:
◆ For desolate area like mountain, island, pasturing area, etc.
◆ For transportation system like beacon light, traffic light, street light, etc.
◆ For communication system: unattached operation microwave middle station, optical cable maintenance station, etc.
◆ For solar power station, wind-solar power station, park charging station, family power house, factory power station, etc.
◆ For solar building: has good business future.
◆ For the new technology application project.
