Hydrotherm 26-3211 Transformer 50VA 120V PRI/24V SEC

The Hydrotherm 26-3211 Transformer 120V primary to 24V secondary, 50VA is an electrical step-down component used in boiler control circuits to supply low-voltage power for the system. It converts standard line voltage into a stable output needed for relays, thermostats, and safety systems. In HVAC systems, it is installed inside furnaces, boilers, and packaged heating equipment to power control boards, pressure switches, and ignition components. The transformer ensures consistent control voltage supply supporting safe sequencing and accurate operation of heating system electrical controls.
