Information About 250SV43B
The 250SV43B is a buck and boost transformer manufactured by Square D for flexible voltage adjustment applications. It is commonly used to compensate for over-voltage or under-voltage conditions by interconnecting the primary and secondary windings. The transformer features a dry-type design with an 80 °C temperature rise rating and is suitable for demanding electrical environments. Its NEMA 3R enclosure provides protection against rain, sleet, and external moisture exposure.
Key Features:
- Buck and Boost Transformer Design: Allows voltage correction by stepping voltage up or down.
- Autotransformer Capability: Primary and secondary windings can be interconnected.
- 0.25 kVA Power Rating: Suitable for small load voltage adjustment applications.
- Dual Secondary Voltage Output: Provides 12 VAC or 24 VAC secondary options.
- Single-Phase Operation: Designed for standard single-phase electrical systems.
- NEMA 3R Enclosure: Rated for indoor and outdoor installations.
- Dry-Type Construction: Requires no liquid cooling or maintenance.
The 250SV43B delivers the reliability and precision required for voltage correction and control in electrical distribution systems.
