Static Frequency Converter I-PTETR-5-400-50 for Adjustable Power Supply

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; <ul> <li>- possibility of operation with overload of 1.1 INOM during one hour;</li> </ul>-emergency protection against short-circuit currents (internal and external), unacceptable voltage drop of the input voltage; -thermal protection; <ul> <li>- local and remote control;</li> </ul>-light signalling of the presence of voltage at the converter input, of the converter switched on state, about overload, about protection operation.
