Description
The Trane TRR01998 Auto Transformer 150VA, 480/600V primary, 240V secondary is an step-down control to supply low-voltage power for circuits. It converts higher line voltage down to a stable AC output, which is used to operate components such as relays, contactors, boards, and sensors. The rating indicates its capacity to handle small electrical loads of control systems. Mounted inside rooftop units, air handlers, or packaged equipment, it ensures voltage supply and protects sensitive components from direct exposure to high line voltage conditions, supporting safe and consistent system operation in HVAC systems.
