Application:
Widely used in power plants,substations,hydropower stations,communication,data centers,signals,railways,industrial production,military research and other fields.
Introduction:
Our industrial inverter is the fourth generation of intelligent inverter power supply which is developed with new digital technology to meet the high reliability requirement of power system. Using SPWM pulse width modulation technology,IGBT power module and output isolation transformer.The output of inverter power supply is a pure sine waveform with features of stable frequency and stable voltage, filtering noise, free from grid fluctuation and low distortion. The inverter has the advantages of strong load-carrying capacity, good load compatibility, wide DC input voltage range, etc.
Our industrial inverter has 3 modes which can be choosed (optional ): Pure DC power supply mode: pure DC input, when DC power cut off,the inverter is shutdown to stop working. DC main supply mode: DC and AC double inputs, DC supply power in priority, AC standby; when DC power cut off,inverter automatically switches to AC power supply. AC main supply mode: DC and AC double inputs, AC power supply is priority, DC standby; when AC power cut off, inverter automatically switches to DC power supply.
Features:
Adopted SPWM pulse width modulation technology, with IGBT power module and output isolation transformer.
Design of user-friendly LED /LCD interface.
Automatic bypass conversion, to achieve uninterrupted work load.
With RS232 communication interface. (optional)
With anti-back connection, under-voltage, over-voltage, overload, short circuit protection,ect.
