Product Description P/N: 0-57491

Description / Specifications

Description

 

The 0-57491 power supply module, manufactured by Reliance Electric, serves to convert 115 VAC input power into DC voltages required for the operation of other modules within the rack. 

Upon powering up, the 0-57491 initiates a "soft start" process, gradually increasing its output voltage until reaching the required level for logic operations to commence. 

In case of AC input voltage dropping below the lower limit, the module automatically generates a power fall interrupt signal at least three milliseconds before the loss of regulated DC power. This ensures a holdover time of 20 milliseconds on AC input loss. 

During a power fail interrupt, 5 Volts of output power are provided by any installed battery backup, preserving the volatile memory of processor modules and the common memory module. However, if the battery backup voltage drops below 3.0 Volts, memory will be lost, and processor modules will cease operation until the power supply is manually reset by turning the front panel's keyswitch to the PROGRAM position.
