Trane Control Transformer Primary Secondary Transformers

Trane control transformers are primary/secondary step-down transformers for HVAC equipment. They convert the incoming line voltage to a lower control voltage, which powers the low-voltage control circuits in heating, cooling and air handling systems. These are also commonly called HVAC control transformers or step-down transformers.

Key Features:

• Primary and secondary windings isolate and step down line voltage for the control circuit
• Supplies power to components such as contactors, relays, thermostats and control boards
• Designed as replacement parts for Trane equipment
• Available in several voltage and VA configurations to suit different equipment requirements

Choose the variant whose input voltage, output voltage and VA rating match your equipment. A correctly rated transformer helps keep the control circuit reliable.
