Description
Ensure stable electrical distribution and reliable operation in commercial and larger residential HVAC systems with the Trane TRR0664 transformer — a robust OEM transformer designed to step voltage levels up or down as needed to power control circuits and auxiliary components. This critical electrical part helps your system convert high voltage from the main supply into usable lower voltages for controls, relays, and wiring — keeping everything running safely and effectively.
Key Features
- Wide Input Voltage Range: Accepts 460 V or 575 V primary voltage commonly found in commercial HVAC systems.
- Dual Secondary Output: Provides 115 V or 230 V secondary voltage to power internal controls and electrical circuits.
- 350 VA Capacity: Offers ample power handling (volt-amp rating) for control boards, relays, sensors, and other electrical loads.
- Genuine OEM Quality: Built to Trane specifications for reliable fit, performance, and long service life.
- Versatile Application: Ideal for commercial air handlers, packaged units, rooftop systems, and other equipment requiring voltage conversion.
