Static Frequency Converter I-PTET-29.2-380-50 for AC Motor Applications

Frequency converter I-PTET-29,2-380-50 is designed to supply consumers (asynchronous motors) with alternating current with frequency 50 Hz, voltage 380 V from two DC networks with voltage from 175 to 320 V.
The device provides:
- uninterrupted power supply of the load with consumed power up to 21 kW with automatic switching to the reserve network when the parameters of the main network deviate beyond the permissible limits and reverse switching to the main network when the parameters of the main network are restored;
- local and remote control, providing motor starting and stopping;
-reception and output of information signals by means of "dry contacts";
-protection against internal short-circuit currents, including in control and signalling circuits;
-thermal protection in control and signalling circuits;
-protection against output overvoltages;
-local and remote control;
-light signalling on the front panel of the device.
