Description
The Daikin-McQuay 4EPC9177 Transformer is an essential control component used in refrigeration equipment to supply low-voltage power for control circuits. It converts higher line voltage, typically 277V or 460 VAC, to a stable 24 VAC output required for thermostats, relays, contactors, sensors, and control boards. Installed inside rooftop units, air handlers, or packaged systems, it works as the main power source for the units’ low-voltage control network in HVAC systems. With a 75 VA rating, it is sized to handle multiple control loads while maintaining reliable voltage delivery for safe and consistent system operations.
