Description
The Trane TRR01121 Transformer steps down high primary line voltage to power secondary control circuits and auxiliary equipment. Installed inside control enclosures in HVAC systems, its electromagnetic primary windings accept either 240V or 480V input at 50/60Hz and convert it to a 120V secondary output. Wiring terminals connect incoming power lines to the primary outlets while delivering transformed power from the secondary side to control modules, relays, and auxiliary components. Converting high input voltage supplies stable electrical current to secondary circuits, supporting continuous equipment control, safe voltage step-down, and stable system power distribution.
