The converter is designed to provide the consumer with an alternating three-phase linear supply voltage of 230 V 50 Hz. The converter is powered from a three-phase network 380 V 50 Hz
with the possibility of additional power supply from external accumulator batteries.
The device provides:
-galvanic isolation of input and output circuits;
-setting of output line voltage in the range from 0 V to 220 V at constant frequency;
-protection against exceeding the permissible temperature of power circuit elements;
-protection against exceeding the output power above 1.2 Rnom;
-protection against internal short circuits;
-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;
-light signalling of on/off status;
-light signalling...
