MARS 50319 Transformer
The MARS 50319 Transformer is a heavy-duty, multi-tap HVAC control transformer engineered for versatile voltage step-down in commercial and residential climate systems. As a 50VA NEMA Class II power source, this unit provides the necessary 24VAC output to drive thermostats, contactors, and integrated circuit boards. The primary side supports 120/208/240/480V inputs, making it a "truck-stock" essential that can replace a wide range of OEM or Honeywell AT150F models. This multi-mount control transformer features 8-inch color-coded leads and a built-in circuit breaker for secondary protection, eliminating the need for external fusing in tight control cabinets. Constructed with welded laminations to ensure quiet, vibration-free operation, the 50319 maintains low heat rise characteristics even under continuous duty cycles. Whether you are servicing a rooftop package unit or a furnace control circuit, the UL 1585 recognized construction ensures high-level reliability and electrical safety compliance. Its flexible mounting plate allows for foot, hub, or 4x4 box installation, streamlining field replacements for technicians.
Key Benefits for Contractors:
- Universal Primary Voltage: Seamlessly handles 120V, 208V, 240V, and 480V inputs for maximum compatibility.
- Integrated Safety: Features a manual reset circuit breaker to protect the 24V control circuit from overloads and shorts.
- Quiet Operation: Precision-welded laminations prevent the common "hum" or buzzing associated with lower-quality transformers.
- NEMA Class 2 Rated: Meets UL 1585 standards for energy-limiting performance in low-voltage HVACR applications.
- Flexible Installation: Multi-mount design with a 4"x4" plate facilitates quick mounting in various orientations.
Common Questions:
Can the MARS 50319 replace a 40VA transformer?
Yes. Because it is rated for 50VA, it provides more power capacity than a 40VA unit, making it a safe and robust upgrade for most standard 24V control circuits.
What happens if the secondary circuit shorts out?
The integrated circuit breaker will trip to protect the transformer and the system's control board. Once the short is identified and repaired, the breaker can be manually reset.
Is this transformer suitable for dual-voltage systems?
This is a multi-tap unit, meaning it can be wired for various input voltages. It is ideal for 208/240V systems frequently found in light commercial HVAC equipment.
