The transformer steps down high-voltage line power (120\/208\/240 VAC) to the safe low-voltage (12\/24 VAC) needed to energize your system's control board, thermostat circuit, and all 24V control components. When this transformer fails, the entire control circuit goes dead — the thermostat goes blank, the system won't call for heating or cooling, and the unit will not respond to any commands. Replacing it with the correct OEM part restores factory-spec voltage regulation and protects your downstream control electronics from damage.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 50VA rating | Primary: 120\/208\/240 VAC | Secondary: 12\/24 VAC | Single phase | 60 Hz | CSA listed | Part # P201-35150\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This genuine Carrier\/Totaline OEM transformer is wound to exact factory VA and voltage tolerances.
