The CCC PSMU-350-3 is a multi-functional module for industrial automation, primarily used as a power management unit or control module. It is widely applied in compressor control systems, refrigeration and air conditioning, power equipment, and safety instrumented systems (SIS). Some sources mention that it may integrate frequency converters, three-phase contactors, or redundant control functions. It supports 220V/400V AC three-phase power input, with an output power of 350W and a rated current of 350A (some models). It features voltage regulation, current protection, and overload capacity. It supports differential input and analog/digital conversion, and some configurations are compatible with Modbus TCP/IP, RS-232/485, and other protocols. It employs a triple modular redundancy (TMR) architecture, supports hot-swapping, and ensures that a single point of failure does not affect system safety.
