MARS 44507 Transformer

MARS 44507 Transformer

The MARS 44507 Transformer is a heavy-duty, foot-mounted solution engineered specifically for high-voltage commercial HVACR control circuits. This 40VA control transformer provides a reliable step-down from a 277V primary input to a stable 24V secondary output, ensuring consistent power delivery for intensive diagnostic and operational tasks. Designed with NEMA Class II construction, it maintains low heat rise during continuous duty, protecting sensitive electronic components within air handlers, rooftop units, and commercial furnaces. The MARS 44507 features color-coded wire leads for both primary and secondary connections, facilitating rapid field installation and precise phase identification. Whether you are replacing a failed 277V to 24V transformer or outfitting a new commercial installation, this unit offers the rugged 50/60 Hz performance required to drive thermostats, contactors, and integrated circuit boards without voltage fluctuations.

Key Benefits for HVACR Technicians:

  • Universal Foot Mount Design: Simplifies mounting in tight electrical cabinets and control panels for 277V HVAC systems.
  • Enhanced Thermal Efficiency: Low heat rise design prevents overheating in high-ambient rooftop environments.
  • NEMA Class 2 Certified: Meets strict safety and performance standards for 40VA power ratings in commercial equipment.
  • Simplified Wiring: Factory-stripped wire leads allow for direct integration with existing 24V control circuits.
  • Broad Compatibility: Serves as a direct replacement for various 277V step-down transformers in commercial air conditioning and heating units.

Common Questions:

Can I use this MARS 44507 for a 120V or 208V primary application?
No. This specific model is engineered for a 277V AC primary input. Utilizing a lower voltage will result in insufficient secondary output, while the wrong voltage can damage the internal windings. Always verify your line voltage before installation.

Is this transformer suitable for powering multiple zone valves or large contactors?
This unit is rated at 40VA. You must calculate the total volt-ampere draw of all connected 24V components to ensure it does not exceed this capacity. For high-draw systems involving multiple large solenoids, verifying the total load is critical for long-term reliability.

Does the MARS 44507 include an internal circuit breaker?
The 44507 is an open-construction Class 2 transformer and does not feature an integrated resettable circuit breaker. It is essential to ensure your control circuit is properly fused according to local codes and manufacturer specifications.
