Product Description

The 57C493 is a Reliance Electric Powered Supply. This power supply may have also been sold under the Asea Brown Boveri and/or Baldor Reliance product lines depending on what years it was actually in production. None of these companies still maintain the 57C493 and it may be a little hard to track down. AX Control does make every effort to keep it in stock as either a refurbished or new surplus part.

The 57C493 is a 376 W Power Supply Module that has an input voltage of 100-132 VAC. It has a nominal input frequency of 50/60 HZ. It has an isolation rating of 1500 VAC input-to-input or 600V DC output-to-rack.  This module features captive ejectors, a removable terminal switch, and over-voltage/over-current protection. This module features a protective aluminum chassis and a heatsink.

The faceplate on the 57C493 has a few different features. It has two LEDs that are labeled POWER and FAULT. It has a key switch that is labeled PROGRAM, MEMORY PROTECT, and SETUP.  It has a replaceable fuse that is 250V. It has a spot for a Battery Back-Up. It also has a covered terminal strip that is labeled L2 120VAC L1. This power supply takes up three slots on an AutoMax Storage Rack and must be the leftmost item on the rack. You can attach this power supply to the rack using a set of mounting screws and the brackets that are on the rack and the faceplate. You can also use the faceplate brackets to safely remove the power supply from the rack when needed.
