Compatible Replacement & Equivalent Models
If the 57C331 is discontinued or on extended lead time, the following models may serve as functional equivalents or replacements depending on your drive configuration:
- Reliance Electric 57C330 — Earlier revision of the same power supply family; verify firmware compatibility
- Reliance Electric 57C332 — Later revision; may offer enhanced protection features
- Rockwell Automation / Allen-Bradley equivalent — Post-acquisition, some GV3000 components were cross-referenced to AB catalog numbers; consult Rockwell for cross-reference
- Third-party compatible PSU boards — Available from certified repair houses; must match output voltage/current specs exactly
⚠ Important: Always verify part revision, firmware version, and drive model compatibility before substituting any power supply module. Contact [email protected] for a free compatibility check.
