ABB Bailey PHARPS03000000 Power Supply Module

This compact power supply module delivers regulated DC power for INFI 90 system racks. The ABB Bailey PHARPS03000000 converts AC input into stable outputs for logic and field circuits. A high-efficiency switching design generates minimal heat inside control cabinets. Consequently, plant engineers can rely on this module for continuous automation system operation.

Technical Specifications of the Power Supply Module

The ABB Bailey PHARPS03000000 measures 170 mm in width and 110 mm in height. Its depth reaches 130 mm for standard INFI 90 rack mounting. The module weighs approximately 1.6 kg including all internal components and heat sinks. A single front panel LED shows output voltage status 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 PHARPS03000000 automatically selects the correct input voltage range without jumpers. You can use this module as a standalone supply or in redundant configurations. The unit provides soft-start circuitry to limit inrush current during power-up. A front panel test point allows quick voltage verification with a standard meter. Consequently, this power supply ensures stable operation for INFI 90 I/O modules and controllers.

Installation and System Integration

You must install this power supply module into a dedicated INFI 90 rack slot. The ABB Bailey PHARPS03000000 connects to the backplane automatically upon full insertion. The module requires adequate clearance around its ventilation slots for cooling. A hinged terminal cover protects field wiring connections from accidental contact. Always verify total load current before adding modules to the rack system.

Maintenance and Operational Benefits

Because the ABB Bailey PHARPS03000000 uses no battery, it needs no periodic battery replacements. Technicians can replace the module without losing any system configuration or user data. The fanless design eliminates noise and reduces mechanical wear over time. Consequently, this power supply offers reliable, maintenance-free service in industrial environments.
