Explosion-proof frequency converter is a kind of explosion-proof industrial control equipment widely used in grain and oil storage of various chemical plants. It is mainly used to adjust the speed of ordinary three-phase asynchronous motor by changing the output power, so as to meet the production process requirements or achieve the purpose of power saving. The power saving rate can reach 30~60%. Can also be through the sensor, transmitter and other control circuit to form a closed-loop speed regulation system, simple installation and operation, constant power factor, but also with fault display and other functions.

Suitable for zone 1, zone 2 dangerous places; IIA, IIB inflammable and explosive gas environment; Indoor and outdoor working environment.

Features: flameproof shell using aluminum alloy or steel plate welding, surface spray plastic; Internal can be installed all kinds of frequency converter (by the user to choose or provide), circuit breaker, signal lamp, instrument and other components; With over current, short circuit, over voltage, under voltage, break equal protection, digital display frequency, speed and load rate or current, can be manually adjusted frequency, speed can be set according to the time change process curve, can also be given by the DCS system signal to control the frequency; Can use steel pipe or cable wiring.

The power of inverter can be loaded for 1.5~45KW, if you need a 45KW inverter, please specify in addition to the custom form of processing and production, shape installation size diagram can be requested by phone or letter.
