Product Details

Description

This premium 277 to 24 Volt Class 2 transformer is a critical electrical component designed to step down high-line voltage to a manageable 24V output for low-voltage control circuits. Rated at 50VA, this transformer provides the necessary power for thermostats, gas valves, relays, and electronic control boards in commercial and industrial HVAC systems. Engineered for reliability and safety, its Class 2 rating ensures it meets stringent power-limiting standards for electrical protection. It is an ideal replacement part for professional contractors and technicians maintaining high-voltage air handlers, ventilation systems, and heating units where consistent voltage regulation is required to prevent component failure.
