MARS 50327 Transformer
The MARS 50327 Transformer is a heavy-duty 50VA control transformer engineered for versatile voltage step-down in commercial and residential HVACR systems. This multi-tap primary unit handles 120/208/240/480V input, providing a consistent 24V secondary output to power contactors, relays, and solid-state boards. Designed with NEMA Class II construction, it features an open-frame design with a manual reset circuit breaker to protect the secondary circuit from overloads. The foot-mount configuration and color-coded wire leads simplify integration into air handlers, furnaces, and refrigeration units. Built for high-demand environments, this MARS 50327 ensures low heat rise and stable 50/60Hz performance, making it a reliable universal replacement for diverse HVAC control circuits. Whether you are servicing a rooftop unit or a residential boiler, this transformer provides the multi-voltage primary flexibility required for professional-grade installations.
Key Benefits- Universal Primary Taps: Supports 120V, 208V, 240V, and 480V, reducing the need to carry multiple single-voltage transformers on the truck.
- Integrated Protection: Features a built-in manual reset breaker to protect downstream 24V components from short circuits.
- Contractor-Grade Durability: NEMA Class II rated with low heat rise for extended service life in high-ambient internal equipment cabinets.
- Easy Installation: Standard foot-mount flange and pre-stripped color-coded leads allow for rapid swap-outs of OEM transformers.
Can the MARS 50327 replace a 40VA transformer?
Yes, this 50VA model provides a higher volt-amp capacity and can safely replace 40VA units, offering additional overhead for complex control strings.
How do I handle the unused primary leads?
Unused primary voltage leads must be individually capped with wire nuts and taped to prevent accidental grounding or shorting within the junction box.
Is this transformer suitable for smart thermostat upgrades?
Absolutely. The 50VA rating is ideal for providing the "C-wire" power required by modern Wi-Fi thermostats and communicating HVAC controllers.
