This heavy-duty step-down transformer converts \u003cstrong\u003e460V primary voltage to 230V secondary at 1564VA\u003c\/strong\u003e, supplying stable power to downstream control circuits and critical system loads. When this transformer fails, the entire unit may go dark — no thermostat response, no contactor actuation, and no blower or compressor operation. Replacing the transformer is the first diagnostic step when all control-circuit functions are lost simultaneously.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 460V primary | 230V secondary | 1564VA rating | OEM part number HT01BC701 | Manufactured by Basler Electric (Factory Authorized Parts)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part, wound and rated to exact OEM specifications.
