Rcd ht680054 Hvac Transformer 40VA 120 to 24 Volt

Product Description

The RCD ht680054 is a low-voltage control transformer designed for residential and light commercial HVAC systems. 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.

This 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.

Key Features

• 120-volt primary to 24-volt secondary step-down conversion
