Compatible Replacement & Equivalent Models
When the original 1MRK002239-BBR01 is discontinued, long lead-time, or cost-prohibitive, the following alternatives may be evaluated as functional equivalents. Always verify electrical and mechanical compatibility before installation.
- ABB 1MRK002239-BBR02 — Revised revision of the same base module; confirm firmware compatibility.
- ABB SR91C790 (bare board) — PCB-level equivalent; requires chassis integration.
- ABB PSMV-01 / PSMV-02 series — General-purpose ABB PSU modules with overlapping voltage specs; verify connector pinout.
- Third-party drop-in PSU modules — Available from certified industrial suppliers; must match output voltage, current rating, and form factor exactly.
⚠ Disclaimer: Konmask.com does not guarantee interchangeability. All replacement decisions must be validated by a qualified engineer against the target system’s requirements.

System Compatibility
The 1MRK002239-BBR01 is primarily designed for use within ABB’s protection relay platform. Compatibility with specific relay models depends on the chassis generation and backplane connector standard. Confirm the following before ordering:
- Target relay or system model number
- Chassis slot designation and backplane pinout
- Required output voltage and current draw of the host system
- Firmware version of the host relay (if applicable)
Contact support@konmask.com with your system details for a compatibility check before purchase.
Selection Guide
Use the following decision flow to select the right power supply module for your application:
- Identify your host system — Confirm the ABB relay or automation platform model and generation.
- Check the original part number — Locate the label on the existing module or refer to the system BOM.
- Verify electrical requirements — Match input voltage range (AC/DC), output voltage(s), and current rating.
- Assess availability — If 1MRK002239-BBR01 is available new, prefer it for full OEM compatibility.
- Evaluate alternatives — If unavailable, review the equivalent models listed above and validate with your engineering team.
- Confirm lead time & condition — Specify whether new, refurbished, or tested-used stock is acceptable for your project timeline.
