Functional Features Realizes complete galvanic decoupling between two input power sources. Front‑panel LED indicator shows status of two input channels and output status. Supports parallel power‑supply mode for capacity expansion besides redundancy mode.
Application Scenarios Redundant power‑supply spare part for high‑reliability industrial control cabinet. Applied in DCS, PLC and safety‑related control system power distribution loop requiring uninterrupted power supply.
Performance Parameters Fast fault‑channel isolation response speed. Stable large‑current power transmission performance.
Material Composition Flame‑retardant plastic housing. Multilayer glass‑fiber epoxy printed circuit board. High‑power decoupling diode assemblies, status indicator and protection circuit. Metal DIN‑rail clamping structure. Screw‑type power wiring terminals.
Structural Characteristics Standard DIN‑rail modular housing. Upper section equipped with two‑group input wiring terminals. Lower section equipped with output wiring terminals. Front‑panel LED status indicators. Rear side has integrated DIN‑rail spring clip for mounting.
Working Principle Two independent 24 V DC power sources connect to two input channels of CP‑A RU. Internal high‑power decoupling diodes isolate mutual influence between two power supplies. LED indicators reflect real‑time status of each input and output loop. Diagnosis circuit monitors internal circuit working condition continuously.
Installation Requirements Completely cut off two groups of input power supplies before replacement. Mount CP‑A RU onto standard DIN rail inside control cabinet. Connect two independent power‑supply sources to input terminals respectively, connect load circuit to output terminals. Tighten all power wiring screws. Restore power supply, verify input channel status indication and output voltage value.
