The transformer steps down high-voltage line power — 120, 208, or 240 VAC — to a safe 12\/24VAC output that powers your system's control board, thermostat, and all low-voltage control circuits. When the transformer fails, the entire control circuit goes dead: the thermostat goes blank, the system won't respond to any commands, and you may find a blown fuse on the control board. Replacing this part restores full low-voltage power and gets your system running again.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 50VA rating | Primary voltage: 120\/208\/240 VAC | Secondary voltage: 12\/24 VAC | Single phase | 60 Hz | 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-authorized transformer wound to exact VA and voltage tolerances.
