Description
The Trane TRR03141 Transformer 100VA 208–240V is a controller that steps down higher input voltage to a stable low-voltage supply for heating and air conditioning circuits. It works through electromagnetic induction between primary and secondary windings to deliver an isolated output for reliable operation of control components such as relays and boards. In HVAC systems, it is used in air handlers, furnaces, and rooftop units to support safe and stable control power. It is placed within the electrical control section and ensures steady voltage regulation and electrical isolation.
