Description
The ABB 1MRK002239-BBR01 is a high-reliability power supply unit (PSU) specifically designed for the Relion 670 and 650 series of protection and control IEDs (Intelligent Electronic Devices). This module ensures stable, ripple-free DC power to the device’s internal processors, binary I/O, and communication boards, maintaining operational integrity during grid disturbances.

Product Q&A
- Q: Is this power supply module hot-swappable?
- A: No, the IED must be powered down and isolated according to safety protocols before removing or inserting the PSU module.
- Q: Does it include a watchdog or “Ready” relay?
- A: Yes, the module features an internal supervision relay (Internal Error Signal) that alerts the system if a power failure occurs.
- Q: Can it handle both AC and DC inputs?
- A: Yes, this specific “BBR01” variant is designed as a wide-range unit compatible with both station battery (DC) and auxiliary AC sources.
- Q: How can I verify if the PSU is failing?
- A: Check the “Ready” LED on the front HMI of the 670 series; if it is dark or red, the PSU or its fuses may be compromised.
