Product Overview
The 1MRK002239-BBr01 is a pluggable power supply module designed for ABB Relion 650 and 670 series protection and control IEDs. It converts station AC or DC auxiliary power into multiple stabilized low-noise internal DC supply rails to power CPU boards, analog sampling modules, binary I/O boards and communication circuits inside the IED. Advanced filtering technology suppresses electrical transients and ripple commonly present in substation auxiliary power systems. Protection engineers and substation maintenance teams use this unit as a direct replacement spare during IED maintenance and panel retrofit projects. Built-in module health monitoring enables the IED to report power supply faults to SCADA for early failure warning.
Application Scenarios
- HV/MV Substation Protection IEDs: Supplies stable power for feeder, transformer and busbar protection relays, ensuring continuous protection operation during minor grid auxiliary voltage fluctuations.
- Wind & Solar Farm Switchgear Cabinets: Powers grid interconnection protection IEDs, adapting to unstable auxiliary power conditions at remote renewable sites.
- Industrial Medium Voltage Distribution Panels: Used in motor protection and bay control IEDs inside factory power distribution systems.
- Hydro & Thermal Power Plant Auxiliary Protection Systems: Provides reliable power for generator and transformer protection relays in power station control cubicles.
