Description
The Trane RR02728 Transformer is an electrical power conversion component designed to step down higher voltage supply to a lower control voltage for safe operation of control circuits. It features a 400V primary input and a 24V secondary output with a 75VA capacity, allowing it to supply stable low-voltage power to control systems. In HVAC systems it is used in air handlers, furnaces, and control panels where consistent voltage reduction is required for thermostats, sensors, and switching circuits. The unit acts as a power conversion module that supports steady and dependable control circuit operation within the system.
