The transformer converts incoming line voltage (120\/208\/240 VAC) down to a safe 12\/24 VAC to power your system's control board, thermostat, and all low-voltage control circuits. When this transformer fails, your system goes completely silent — no thermostat response, no blower operation, and no error codes — because the entire control circuit loses power.\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 | 60 Hz | Single-phase | CSA listed | OEM part number P201-35150\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier\/Totaline factory part built to exact VA and voltage tolerance specifications.
