KUC755AE117 3BHB005243R0117 ABB Power supply module
Product Overview: KUC755AE117 3BHB005243R0117
The KUC755AE117 3BHB005243R0117 is a high-reliability power supply module developed by ABB for use in industrial automation and process control systems, specifically within the AC 800M and related controller architectures. Designed to deliver stable, conditioned DC power to CPU modules, I/O units, and communication interfaces, this unit ensures continuous system operation even under fluctuating input conditions or partial grid disturbances. Its robust construction and compliance with international safety standards make it suitable for deployment in critical infrastructure.
Main Features and Advantages:
Wide input voltage range: The KUC755AE117 3BHB005243R0117 accepts 85–264 V AC or 100–370 V DC input, enabling global compatibility and resilience against brownouts or voltage sags commonly encountered in industrial plants.
High-efficiency power conversion: Utilizes switched-mode technology to deliver up to 120 W of output power with >85% efficiency, minimizing heat generation and reducing cooling requirements in control cabinets.
Redundancy-ready design: Supports parallel operation with an identical module via built-in diode-or circuitry, allowing N+1 redundancy configurations that maintain power delivery during module maintenance or failure.
Comprehensive protection mechanisms: Includes overvoltage, overcurrent, short-circuit, and thermal shutdown safeguards to protect downstream electronics and extend system lifespan.
DIN rail mounting and compact form factor: Integrates seamlessly into standard control panels alongside ABB’s AC 800M controllers and I/O modules, saving space while ensuring mechanical stability.
