GE Fanuc Offers Redundant Power Supply System

GE Fanuc Automation America Inc. (Charlottesville, VA) announced a new redundant power supply system (RPSS) that switches power to a backup unit without process interruption in the event of a primary power supply failure. The RPSS helps ensure uptime in high-availability applications such as pumping stations, process lines, emergency generating, and batching, and minimizes lost production and scrapped products due to power supply failure.

Consisting of a baseplate that supports two power supplies and a redundant power supply adapter, the RPSS is compatible with all Series 90-30 power supplies, CPUs and I/O expansion bases. The adapter mounts in the power supply slot on any CPU or I/O expansion base.

The flexibility of the panel-mounted RPSS allows power from multiple sources; for example, the primary source can be connected to 120Vac and the backup to 24Vdc. Built-in user diagnostics in the redundant power supply's baseplate can be incorporated into the controller or an external alarm for easy troubleshooting. In the event that a power supply fails, users can replace the failed unit by simply removing power from the defective unit and hot-swapping it while the backup unit is powered and controlling the process, further reducing downtime.
