It features modular construction, a DC supply, integrated supply modules, and a rectifier to support regenerative operation. The unit operates with converter input at 3 x AC 380–480 V ±10% and delivers a rated power of 37 kW. Additional capabilities include built-in brake chopper, 24 V stand-by power, external cable damping feedback, and forced air cooling for models rated at or above 110 kW.
