Description

The ABB PHARPS03000000 is a power supply tray component designed for integrated control systems. Designated under the MPS III type series, this hardware serves as a foundational power distribution housing or sub-assembly that supports modular power supply infrastructure. The unit provides dual-channel supply capabilities rated for 24V @ 17A and 24V @ 17A configurations, delivering regulated electrical energy to attached plant instrumentation and control network modules. It is compatible with specialized DCS systems, specifically fitting within the Symphony Harmony INFI 90 architecture to handle underlying hardware power distribution requirements safely and systematically.

Features

• Configured to hold or integrate modular components for the MPS III (Modular Power System III) lineup.
• Provides dedicated capacity for dual 24V outputs at 17A each.
• Built as a standard control system power supply sub-component for rack or cabinet mounting.
• Operates without any internal battery packs, eliminating specific battery preventative maintenance routines.

Applications

• Symphony Harmony INFI 90 process control networks.
• Harmony Block I/O systems and P-HA-REP-RFO hardware assemblies.
• S+ HR Power configurations requiring automated power supply trays.

Installation Guidelines

• Cabinet Enclosure Fit: Verify the cabinet space provides adequate height clearance for the 1066.8 mm framework and depth allowance for 231.14 mm to securely mount the chassis.
• Electrical Safety and Wiring: Ensure standard terminal connections match the separate 24V @ 17A output paths to safely divide current load according to engineering documentation.
• Ventilation and Thermal Load: Maintain designated spacings around the tray inside the module rack to allow heat dissipated from the static converter circuits to exit efficiently.
