Reliance Electric 57493A Power Supply

Reliance Electric 57493A Power Supply is a 376-watt power module designed for Reliance Electric AutoMax PLC systems, providing continuous power to the Card Storage Rack from a 100/120 VAC mains at 50/60 Hz. This unit is commonly cataloged as 57C493 and represents the legacy Reliance Electric (now part of Baldor/Reliance Electric lineage) AutoMax power supply family. It delivers 376 W of continuous output to support the rack and its modules, a specification confirmed in AutoMax power-supply literature and supplier listings. The 57493A typically ships with two key switch keys, reflecting its rack-based configuration and access-control context. Ideal for refurbishment, replacement, or service of AutoMax installations, this power supply enables reliable energy delivery for older AutoMax card storage racks and related components, making it a recognizable, compatible option when maintaining legacy automation systems.
