DSQC 249A 3E041641 | ABB Rectifier

Features:Phase Error IndicationFault Detection AlarmBridge Temperature DetectionThe ABB GME DSQC Series Rectifiers consist of a three-phase, six pulse diode bridge, a reservoir capacitor, a shunt regulator, and control electronics. The control electronics of each rectifier are power supplied by the supply unit. When the mains power is not connected to the rectifier, the shunt transistor is kept closed; however, when the mains power is connected, the shunt transistor is opened and the reservoir capacitor is charged. If too high of a rectifier bridge temperature is detected, an alarm is given via the FAULT-N and the LED fault is lit. This indication remains until any error is corrected. All errors must be rectified in a timely manner in order for the rectifier to function properly.
