1200A DC power system targets data centre and telecoms racks
The Guardian Bulk M series is a 10RU high 19” rack-mounted DC power system that provides a bulk output of -48VDC. The configurable systems incorporate six rectifier shelves with up to 23 high efficiency hot-swap rectifiers, with a maximum total current of 1200A (N+1). The rectifiers of the Guardian Bulk M42 series are internally fan cooled with speed control, providing load and temperature control while keeping acoustic noise to a minimum.
The Guardian Bulk M series includes the rectifiers that have efficiency above 96%, remote monitoring and control, a field replaceable controller and Ethernet communications with SNMPv3. There are three LED Alarm/Status Indicators and ten Form-C Relay Alarms, as well as control for external low votlage devices.
The Guardian Bulk M42 also features ACX advanced controller monitoring systems that control rectifier output and provides LED alarms in the event of system failures. It is also compatible with Unipower’s free PowCom software which offers local and remote management through an advanced Windows graphical user interface.
