Frequency converter is designed to convert the alternating three-phase voltage 380 V 50 Hz into adjustable in frequency and amplitude alternating three-phase voltage with nominal parameters 220 V 50 Hz.
The device provides:
-setting of output voltage frequency 1-70 Hz with regulation characteristic - U/f=const;
-setting of output linear voltage in the range from 0 V to 220 V at constant frequency;
-protection against internal short circuits;
-protection against exceeding the permissible temperature of power circuit elements;
-protection against exceeding the output power above 1.2 Rnom;
-protection against short circuits in the load or in remote signalling circuits;
-protection against phase failure or current imbalance in phases;
-local and remote (via RS-485 interface) control;
-light signalling of the presence of line voltage in the power supply network;
-signalling of readiness for operation;
-signalling of on/off status;
-light signalling of the on/off status; -light signalling of the on/off status; -light signalling of the on/off status; -light signalling of the...
