ABB 1MRK002239-BBR02 Industrial Power Board

Description

The ABB 1MRK002239-BBR02 Industrial Power Board is an industrial-grade power module designed for reliable performance in demanding industrial environments. It features a wide input voltage range, supporting either 24VDC–250VDC or 85–264VAC, and converts alternating or direct input voltage into stable, regulated direct current outputs. Typical multi-channel outputs include +5VDC, +12VDC, and +24VDC, allowing it to supply power to multiple subsystems such as control units, communication modules, and relay protection units simultaneously.

Equipped with comprehensive system protection functions, including overvoltage, overcurrent, and short-circuit protection, the module enhances operational safety and stability for connected equipment. It also supports real-time power supply status monitoring, with outputable working status signals to enable system self-diagnosis and alarm functions. Key design features include high reliability to meet the long-term continuous operation requirements of power systems, strong anti-electromagnetic interference capabilities suitable for high-interference environments like substations, and support for hot-swappable, modular replacement to simplify maintenance and repairs.

Ideal applications include digital substation systems (powering intelligent electronic devices, merging units, remote terminals), ABB series relay protection devices (supplying core protection control circuits), SCADA, human-machine interfaces, data acquisition modules, and integration into relay protection cabinets or protection panels for centralized power supply.
