CCC PSMU-350-34 350 compressor speed control system

CCC PSMU-350-34 350 compressor speed control system

I. Basic Information
Brand: CCC (Compressor Controls Corporation, USA)
Model: PSMU-350-34
Category: Power Supply Module Unit for 350 Series Speed Control System (Power Supply Module Unit for the CPU mainboard, I/O cards, speed monitoring board, anti-surge control loop, panel human-machine unit in the CCC 350 compressor speed control system (gas turbine, centrifugal air compressor, process compressor speed control / anti-surge integrated control system core power supply unit))

Core Functions
Provide multiple isolated and stabilized DC power supplies for the CPU mainboard, I/O cards, speed monitoring board, anti-surge control loop, and panel human-machine unit in the CCC 350 main control cabinet;
Convert AC input to multiple standard DC voltages for power supply to all boards in the entire compressor control system;
Built-in protection against overvoltage, undervoltage, overcurrent, short circuit, and overheating. Power failure will upload system alarms to ensure the safety of the unit operation;
It is a plug-in modular power supply for the control cabinet chassis, which can be replaced online (some configurations support redundant dual power supply parallel operation).

Lifecycle
Original Factory Status: An old classic model, has been officially discontinued (End of Life)
The CCC 350 platform has already been upgraded to the CCC Insight, Triple T series of new control systems, the PSMU-350 series power supply is no longer in production;
Supply Channel
New original factory end-of-life inventory: Very little stock, long procurement cycle, high price;
Disassembled second-hand + professional maintenance refurbished parts: The most commonly used replacement parts in industrial maintenance sites, delivery can include the entire machine with load testing;
Compatibility: Most versions with the same series PSMU-350 suffix can be interchanged and replaced, with minor wiring adjustments.
