It steps down primary voltage from 120 volts to a 24-volt secondary output, supplying the low-voltage control circuit that drives thermostats, contactors, and control boards. Rated at 40 VA and tuned to 60 Hz, this transformer delivers consistent, stable output under normal system load. Measuring 3.8 inches long, 2.85 inches wide, and 2.45 inches tall, it is compact enough to fit standard equipment enclosures. Licensed HVAC technicians performing control-circuit service or system replacements are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis transformer is suited for residential split systems, packaged units, air handlers, and similar HVAC equipment requiring a 120-volt primary and 24-volt secondary control circuit. It is an OEM-replacement-style part intended for systems that originally specify a 120V-to-24V, 40 VA transformer operating at 60 Hz. It is appropriate for both new installations and service replacements where the original transformer has failed or been damaged.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e120-volt primary to 24-volt secondary step-down conversion\u003c\/li\u003e\n  \u003cli\u003e40 VA power rating supports standard HVAC control circuit loads\u003c\/li\u003e\n  \u003cli\u003e60 Hz frequency matches North American power supply standards\u003c\/li\u003e\n  \u003cli\u003eCompact footprint: 3.8 x 2.85 x 2.45 inches for installation in tight equipment cabinets\u003c\/li\u003e\n  \u003cli\u003eOEM-replacement design engineered to factory specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement transformer for HVAC systems requiring a 120-volt primary, 24-volt secondary, 40 VA, 60 Hz control transformer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician.
