ABB 1MRK002239-BBR01 | Power Supply Module

The ABB 1MRK002239-BBR01 is a high-availability power supply module engineered specifically for ABB’s Relion 670 and 650 series protection and control relays, as well as the COMBIFLEX and I层次 (Intelligent Electronic Device) subrack systems. This module is responsible for converting station battery voltages (DC) or alternating current (AC) into stabilized, low-noise DC voltage rails required to power the internal microprocessors, high-speed sampling circuits, and binary I/O boards of protection relays. Given its role in electrical substation environments, it features extreme surge immunity, low ripple output, and comprehensive diagnostic monitoring.

Application Areas

The 1MRK002239-BBR01 is an indispensable component in high-voltage utility and transmission infrastructure:

• Transmission Substations: Powering distance, line differential, and transformer protection IEDs on critical transmission lines.
• Generation Protection: Supporting generator protection relays that monitor stator grounding, over-excitation, and out-of-step conditions.
• Distribution Automation: Providing reliable logic power to feeder management and busbar protection systems in industrial sub-stations.
• Renewable Energy Integration: Powering the grid-coupling protection relays within massive offshore wind hubs and utility-scale solar fields.

Product Usage Instructions

1. Input Configuration & Coding: Before sliding the module into the subrack, check the physical coding pins and the side-label schematic. Ensure that your substation’s battery voltage matches the input designation on the 1MRK002239-BBR01 variant to avoid immediate hardware breakdown.
2. Electrostatic Discharge (ESD) Measures: The module houses high-density filter networks and switching regulators sensitive to static buildup. Always wear a grounded anti-static wrist strap when handling the card or adjusting the rear termination blocks.
3. Physical Installation: De-energize the target subrack slot. Slide the module smoothly along the guide rails of the Relion chassis until the heavy-duty power pins completely engage with the backplane distribution board. Secure the module using the top and bottom captive screws on the front faceplate to ensure solid chassis grounding.
4. Wiring and Grounding: Attach input cables to the corresponding compression terminals on the backplane connector block. Use robust, shielded cabling for the input feed, and ensure the protective earth (PE) connection is established with minimum lead length to dissipate high-frequency grid surges.
5. Initialization Verification: Apply input power. The green “Ready” or “Power OK” LED on the front interface should remain steadily illuminated. If the internal diagnostic relay contacts transfer or an “Internal Error” signal appears on the main IED screen, disconnect power immediately and evaluate the rack for downstream distribution faults.

Common Questions & Answers (Q&A)

Q: Does the 1MRK002239-BBR01 support internal hardware redundancy?

A: While the module itself is single-channel, many Relion 670 subracks are engineered to allow the integration of dual, parallel-operating power supply modules. In this configuration, if one module drops offline, the secondary module seamlessly keeps the protection relay functional without resetting the CPU.

Q: What causes the module’s internal fail-safe contact to trip?

A: The signaling contact transfers if the module detects an under-voltage condition on its internal output rails, a sustained thermal overload inside the component housing, or an internal switching component failure.

Q: Can I use this power supply module across different Relion models like REF670 and RET670?

A: Yes. Within the same hardware generation frame (such as the 670 series), the power supply modules are standardized and cross-compatible, provided the internal rack depth and voltage range codes align perfectly with the original engineering manifest.
