Bard S8407-034 - 208/240V to 24V 40VA Transformer

The Bard S8407-034 transformer is an OEM step-down control transformer used in Bard wall-mounted HVAC equipment to convert 208/240V input power to a 24V AC control circuit supply, rated at 40 VA for reliable operation of contactors, relays, and other low-voltage controls. If your unit has intermittent control power, a buzzing transformer, or no 24V output, replacing with the correct Bard S8407-034 helps restore proper control voltage and protects connected components from undervoltage issues. Verify your unit voltage and wiring match 208/240 to 24VAC before ordering, and confirm the part number against your Bard model and serial data for proper fit.
