Frequency converter is designed to convert DC voltage 175-320 V into AC regulated voltage for power supply of actuators with asynchronous motor.
The device provides:
-operation and start of three-phase asynchronous motor with consumed active power up to 1,5 kW
-regulation of the frequency of the first harmonic of the output voltage in the range of 25-50 Hz;
-regulation characteristic U/f=const;
-power supply from two DC feeders, main and backup;
-automatic transition to the power supply from the main feeder to the backup feeder and back;
- possibility of operation with overload of 1.1 INOM during one hour;
-emergency protection against short-circuit currents (internal and external), unacceptable voltage drop of the input voltage;
-thermal protection;
- local and remote control;
-light signalling of the presence of voltage at the converter input, of the converter switched on state,
about overload, about protection operation.
