Product Overview

The PSMU‑350‑3 is a hot‑swappable 350‑W CPCI AC‑DC power supply module manufactured by CCC (Compressor Controls Corporation). It supplies stable +12 V DC backplane power for CCC anti‑surge and turbine‑compressor control rack hardware.

This switching‑mode power unit accepts wide‑range universal AC mains input and converts it to tightly regulated 12 V DC for the CPCI‑based compressor controller system. Built‑in multi‑layer circuit protection safeguards downstream CPU, communication and I/O boards against surges, short‑circuits and over‑temperature events. Front‑panel LEDs provide fast visual diagnostics for power‑on status and fault conditions. Hot‑swap capability allows module replacement while the compressor control rack remains online, minimizing plant downtime for critical rotating‑equipment protection systems. Original OEM production is discontinued; supplied as refurbished / surplus spare parts for existing compressor control system maintenance.

Application Notes

• Exclusively designed for CCC CPCI‑series compressor anti‑surge & performance control racks.
• Hot‑swap function valid only when chassis is powered; observe ESD anti‑static precautions during handling.
• Maintain sufficient cabinet airflow to avoid over‑temperature derating; do not block fan air inlet and outlet.
• Install inside climate‑controlled industrial cabinet; avoid condensation, dust and corrosive gas exposure.
• Verify hardware revision compatibility before installation; follow CCC official hardware installation manual.
• Typical deployment: refineries, petrochemical plants, natural‑gas processing facilities, ethylene plants for centrifugal‑compressor anti‑surge control system spare‑part maintenance and retrofits.
