MARS 50354 Transformer
The MARS 50354 Transformer is a heavy-duty 40VA HVAC control transformer engineered for reliable 24V power distribution in demanding air conditioning, heating, and refrigeration circuits. Designed with an open construction NEMA Class II frame, this unit is a versatile solution for technicians requiring multi-tap primary voltages of 120V, 208V, and 240V. Its compact footprint, featuring a height of less than 2-1/4 inches, makes it an ideal multi-voltage foot mount transformer for tight cabinet installs where space is at a premium. Built to UL 5085 standards, the 50354 ensures a low heat rise and consistent performance under load, whether you are powering contactors, relays, or advanced control boards. The primary and secondary connections use color-coded leads and 1/4-inch male quick connects for fast, error-free wiring in the field.
Key Benefits
- Universal Compatibility: Includes 120/208/240V primary taps to cover almost any residential or commercial application.
- Technician-Friendly Install: The foot-mount configuration and color-coded leads simplify integration into existing systems.
- Space-Saving Design: Ultra-compact 2.24" height fits into specialized equipment housings where standard transformers fail.
- Robust Safety: UL Class 2 recognized construction provides inherent protection for low-voltage control circuits.
- Reliable Output: Delivers a steady 24V secondary output at 40VA to prevent control chatter and voltage drops.
Common Questions
What can I use as a replacement for the MARS 50354?
This unit is a direct foot-mount transformer replacement for the Packard PF42440, Supco SXT105/SXT115, and Honeywell AT140A1018. It is frequently used across brands like Carrier, Goodman, and York.
How do I wire the multi-tap primary for 240V?
Always reference the wiring diagram on the housing. Generally, for a 240V application, you utilize the common (White) and the 240V tap (typically Orange), ensuring unused leads are capped with wire nuts to prevent shorts.
Is this transformer suitable for both heating and cooling systems?
Yes, its 40VA rating is specifically designed to handle the inrush current of most standard HVACR contactors and control circuits found in furnaces, air handlers, and condensers.
