8407-045 OBSOLETE
- Transformer 120/24V 40VA
Bard 8407-045 is an OEM control transformer used in Bard wall mounted HVAC equipment to step down 120 volt line power to 24 volts for low voltage controls, helping power thermostats, relays, contactors, and other control circuits. Rated at 40 VA, it is sized for common Bard control loads and is a solid choice when troubleshooting low voltage failures such as no 24V output, intermittent control power, or blown secondary protection. Verify primary and secondary voltage requirements and mounting or wiring configuration against your unit wiring diagram to ensure correct fit and safe restoration of reliable 24V control power.
