Taco 569-2 40VA Transformer – 120V to 24V Power Supply for Zone Valve Applications

The Taco 569-2 is a 40VA class 2 transformer designed for use in low-voltage hydronic heating control systems. It converts 120V line voltage to a 24V secondary output, delivering reliable power to zone valves, thermostats, relays, and other 24V control devices commonly found in residential and light commercial heating applications.

This transformer is suitable for general-purpose use where isolated 24V control voltage is required. It features a compact enclosure for wall or panel mounting and is commonly installed in mechanical rooms, control panels, or adjacent to zone valve control modules.

Product Features

• Primary Voltage: 120V, 60Hz, single-phase
• Secondary Voltage: 24V, 60Hz, single-phase
• Output Rating: 40VA
• Type: Class 2 power-limited transformer
• Application: Supplies low-voltage power for zone valves, thermostats, and control systems

Installation Notes

The 569-2 transformer should be installed in accordance with local electrical codes. All wiring must be completed with power disconnected. Mounting hardware is included for fixed surface installation. Verify system load before installation to ensure that the total VA requirement does not exceed the 40VA output rating.

Contractor Applications

Designed for field service, system expansions, or new control system installations, the Taco 569-2 provides isolated 24V power for up to several low-voltage control components, depending on total current draw. It is frequently used in conjunction with zone control relays or individual zone valves in hydronic systems.
