Static converter SIF 750-E-28V
The static converter for tramcar auxiliary services is designed for the charging of the vehicle's batteries and supplying its consumers with 28Vcc. It is designed with IGBT technology, working at a high frequency based on PWM with DSP; the voltage is kept constant at the batteries terminals, compensating voltage failures on various devices.
