PHARPS32010000 is a power supply unit belonging to the Modular Power System III (third-generation modular power system). Designed for use with the PHARPSCH100000 power chassis, it supports redundant parallel operation and accepts an input voltage of 120/240V AC (47–63Hz). It provides multiple simultaneous DC outputs—such as -5V @60A, +15V @3A, -15V @3A, -24V @17A, and -125V @2A—with a total power output of approximately 175W. Key functions include protection against overvoltage, overcurrent, short circuits, and overheating, as well as power status monitoring and fault alarming. The complete power supply assembly includes the power chassis, backplane, and fan slots.

Architecture: AC-DC multi-channel isolated regulated power supply supporting N+1 redundancy; multiple PHARPS modules can operate in parallel with load sharing, ensuring rack power continuity even if a single module fails.

Installation: Plug-in rack-mount card format; installed within the PHARPSCH power chassis and cooled by an associated fan unit.

This power module directly supplies power to the following components:

All cards within INFI90 / Harmony racks

Controllers: Early INFI90 MFP models and later BRC series

I/O modules: INFI90 rack cards such as AI/AO/DI/DO, RTD modules, pulse cards, etc.

Communication cards and terminal interface cards
