The transformer steps down incoming line voltage (120\/208\/240 VAC) to a safe 12\/24 VAC to power your system's control board, thermostat, and all low-voltage circuits. When this transformer fails, the entire control circuit loses power — resulting in a completely unresponsive thermostat, a system that won't turn on, or a board that won't communicate. Replacing this part with the correct OEM unit restores proper voltage regulation and protects your system's sensitive electronics.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 50 VA rating | Primary voltage: 120\/208\/240 VAC | Secondary voltage: 12\/24 VAC | 60 Hz single-phase | CSA listed | Totaline\/Carrier OEM part number P201-35150\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This factory-authorized OEM transformer is wound to exact VA and voltage tolerances for the YAC48110YACX404AC.
