240V to 24V Step-Down Transformer

About the Step-Down Transformer

The 240V to 24V Step-Down Transformer is the power source that lets a 24V AC zoning system run from standard Australian mains. It accepts 240V AC input and delivers a stable 24V AC output at 2 amps — enough current to power a typical 4-to-6-zone installation, including the zone controller and each of the connected damper actuator motors, without approaching the transformer's rated ceiling. Installers wire the primary side into a switched mains connection in the roof space or plenum, and the secondary side feeds the zone controller's low-voltage input. Because it is purpose-built for HVAC zoning, the output specification matches the input requirements of the F03 Damper Actuator Motor and the Austra Supply 4 & 6 Zone Controller exactly, avoiding the compatibility guesswork of using a generic transformer. Common uses include new zoning installations, replacement of failed transformers on existing systems, and upgrades where zone count has grown beyond the original transformer's rating.
