Trane SFTRR75VA Transformer
The Trane SFTRR75VA is a heavy-duty 75VA step-down transformer engineered specifically for industrial and commercial HVACR control circuits. This multi-tap OEM replacement part provides maximum field flexibility, allowing technicians to pull from primary voltages of 120V, 208V, 240V, or 480V to deliver a stable 24V secondary output. Built with a high-grade silicon steel core and copper windings, it ensures minimal energy loss and superior thermal stability during continuous operation. As a Class 2 transformer, it meets strict safety standards for powering sensitive electronic modules, relays, and contactors. The compact frame and robust mounting footprint make the SFTRR75VA a direct fit for Trane air handlers, rooftop units, and chillers. Whether you are performing a control circuit troubleshooting procedure or a full system overhaul, this component provides the high volt-ampere rating necessary to handle increased inrush currents without voltage sag.
Key Benefits- Universal Compatibility: Multi-tap primary inputs (120/208/240/480V) eliminate the need to stock multiple SKUs for different line voltages.
- High Power Capacity: Rated at 75VA, providing ample overhead for complex control strings and multiple 24V accessories.
- Enhanced Reliability: Genuine Trane OEM construction ensures precise voltage regulation and long-term durability in harsh environments.
- NEMA Class 2 Certified: Specifically designed to protect low-voltage control circuits from high-voltage spikes and surges.
Can the SFTRR75VA replace a 40VA or 50VA transformer?
Yes, as long as the primary/secondary voltages match, a 75VA transformer can replace a lower-rated unit (like 40VA or 50VA) because it provides a higher capacity to handle the load. Never replace a higher VA unit with a lower VA unit.
What is the maximum current output for the 24V secondary?
The 75VA rating allows for approximately 3.125 Amps at 24V. This makes it ideal for HVAC control systems with multiple solenoid valves or high-draw contactors.
Is this transformer compatible with 50Hz and 60Hz systems?
Yes, the Trane SFTRR75VA is designed to operate efficiently on both 50/60Hz frequencies, supporting a wide range of domestic and international power supplies.
