TRR00664
The Trane TRR00664 Transformer is an element of power conversion in commercial HVAC systems, which provides regulated voltage to electrical circuits and control parts. Its main purpose is to reduce the input electrical power from a 460 to 575 V primary input converts to a 115 to 230 V secondary output of 350 VA, which is safe to operate relays, contactors and control boards. This is because the mechanism works by electromagnetic induction between internal windings which control the transfer of voltage. They are normally installed in the electrical compartment of rooftop units, air handlers or packaged HVAC system units.
