System components: Backplane power supply SFC050

The SFC050 AC power supply works independently or in conjunction with a second SFC050 redundant power supply module to increase power safety for the application. It is designed for an external voltage of (90 VAC - 264 VAC). When two redundant power supplies are used, this implies that only one will be providing energy to the system while the other one stands by for backup purposes. In the event of a failure, the backup will automatically assume operation. A relay is provided to indicate failure on each of the power supplies giving the user a chance to replace the faulty one. The SFC050 module provides two voltage outputs: 5 VDC @ 3 A distributed via the rack backplane to feed module circuits 24 VDC @ 300 mA for external use through the terminals 1B and 2B. The AC voltage input, the 5 VDC output and the 24 VDC output are all mutually isolated.
