This is a high-capacity step-down transformer that converts 460V primary power to a 230V secondary output at 1564VA, providing clean, stable voltage to internal control and power circuits throughout the unit. When this transformer fails, the result is typically a complete loss of system operation — no heating, no cooling, no fan — because downstream components are starved of their required operating voltage.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 460V Primary | 230V Secondary | 1564VA Rating | OEM Part# 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 Factory Authorized Parts (FAP) OEM transformer, wound and rated to exact Carrier specifications.
