This high-capacity 75VA transformer is a critical electrical component designed for HVAC systems and industrial control circuits. It efficiently steps down high incoming line voltage (208V or 230V) to the standard 24V required to power thermostats, relays, and integrated control boards. Ideal for residential and commercial heating and cooling equipment, this replacement transformer ensures your system's control circuit receives consistent, reliable power. Whether you are troubleshooting a furnace that won't start or an air conditioner with no power to the thermostat, this 50/60Hz versatile transformer is a robust solution for restoring system functionality. Its 75VA rating provides ample power for complex systems with multiple secondary loads.
