ABB Bailey PHARPS21010000 Power Supply Module

This power supply module provides regulated DC power for ABB Bailey INFI 90 systems. The ABB Bailey PHARPS21010000 converts AC mains into stable 5V and 24V outputs. A high-efficiency switching design minimizes heat generation within control cabinets. Consequently, plant engineers can rely on this module for continuous system operation.

Technical Specifications of the Power Supply Module

The ABB Bailey PHARPS21010000 measures 250 mm in width and 110 mm in height. Its depth reaches 150 mm for standard rack mounting. The module weighs approximately 2.4 kg including all internal transformers and heat sinks. A single front panel LED array shows output status, overload, and fault conditions. The rear side uses a 24-pin backplane connector for power distribution. This design stores minimal energy in small filtering capacitors only. Therefore, the module contains no batteries for energy storage.

Functional Features and Power Distribution

The ABB Bailey PHARPS21010000 includes overvoltage and overcurrent protection on all outputs. You can operate the module in parallel for redundant power configurations. The unit automatically switches between AC and DC input sources without interruption. A front panel test point allows voltage verification during troubleshooting. Consequently, this power supply module ensures stable operation for INFI 90 I/O and CPU modules.

Installation and System Integration

You must install this power supply module into a dedicated rack slot. The ABB Bailey PHARPS21010000 connects to the backplane automatically upon insertion. A hinged front cover protects output terminals from accidental contact. The module requires adequate clearance for air circulation around the heat sink. Always verify total load current before adding modules to the rack system.

Maintenance and Operational Benefits

Because the ABB Bailey PHARPS21010000 uses no battery, it needs no periodic battery changes. Technicians can replace the module without losing any system configuration data. The fanless design eliminates noise and reduces maintenance requirements. Consequently, this power supply offers reliable service in demanding industrial environments.
