Pure sine wave inverter used in hazardous areas for converting DC into AC power

Explosion-proof inverter is an electronic device that can convert DC power into AC power for use in flammable and explosive environments. This pure sine wave inverter can be customized according to specific requirements.

Applications

Hazardous locations in Zone 1 and Zone 2, such as coal mines, distilleries, gas stations, etc.
Explosive gas environments of IIA, IIB, and IIC levels, such as flour mills, aluminum powder plants, metal mines, graphite plants, etc.

Features

Explosion-proof inverter adopts Mitsubishi's sixth-generation IPM module, with stable performance and a designed service life of over 15 years.
Cast aluminum alloy housing with surface spray coating.
Explosion-proof level is EXdIIBT4.
Built-in power frequency isolation transformer offers strong anti-interference capability.
Complete protection functions, including input undervoltage and overvoltage protection, output overvoltage, overload, over-temperature, short circuit, self-diagnostic protection, etc.
Pure sine wave output offers fast transient response speed.
