Information About 0-51890-5
The 0-51890-5 is a DPSF Phase Sequence Circuit Board used across Reliance Electric drive systems and may also appear under Baldor-Reliance or ABB branding due to shared manufacturing. The board includes a metal faceplate with a labeled phase-sequence LED indicator wired directly to the PCB. Its layout features a printed grid pattern for reference, with components including mixed diode types, resistors, polyester film capacitors, and large electrolytic capacitors. Designed for straightforward panel mounting, the board incorporates three factory-drilled mounting points and a conductive rear tab for electrical interfacing. Its purpose is to determine whether the incoming three-phase AC power is wired in the correct sequence, allowing drive systems to operate safely and preventing reverse rotation or motor damage.
Key Features
- Dedicated phase sequence monitoring: identifies correct or reversed AC phase wiring conditions.
- Dual-voltage capability: supports 208–240 VAC and 380–480 VAC inputs for broad system compatibility.
- LED-based indication: front-panel green/red LED provides immediate visual phase status.
- Simple panel mounting: three-hole design ensures secure installation inside drive cabinets.
- Industrial-grade construction: includes diodes, resistors, and robust electrolytic capacitors for long-term reliability.
- Wide environmental tolerance: operates from 0°C to 50°C with high humidity resistance.
- Compatible with multiple OEM labels: used in Reliance Electric, Baldor-Reliance, and ABB drive platforms.
- Compact form factor: small board size simplifies integration into existing control assemblies.
The 0-51890-5 delivers the reliability and precision required for safe and accurate phase verification in Reliance Electric drive systems.
