The DIVERSITECH pf12406 is a Class II step-down transformer rated at 40 volt-amperes (VA), designed for low-voltage HVAC control circuits. It accepts a 120-volt primary input and delivers a 24-volt secondary output at 60 Hz, making it a direct fit for thermostat and control board wiring in forced-air heating and cooling systems. The unit uses a foot-mount configuration with wire leads for straightforward installation. Licensed HVAC technicians working on residential and light commercial equipment will find this transformer a practical replacement for failed or undersized low-voltage transformers.
This transformer is suited for both ducted and ductless system applications. The multi-foot mounting base provides flexibility when securing the unit to a furnace or air handler chassis. It is listed as a replacement for Rheem OEM transformers, making it a go-to option for service calls on Rheem equipment where the original transformer has failed or is no longer available. The wire-lead terminations allow connection to standard low-voltage wiring without specialized connectors.
Listed as an OEM-style replacement for Rheem low-voltage control transformers. Suitable for both ducted and ductless HVAC systems requiring a 120-volt primary, 24-volt secondary Class II transformer with a foot-mount configuration.
Installation should be performed by a licensed HVAC technician. Disconnect all power to the unit at the disconnect switch or breaker before removing the failed transformer or making any wiring connections. Verify that the existing low-voltage wiring and control board are rated to work with a 40 VA supply before energizing. Follow applicable local codes and manufacturer wiring diagrams when terminating the wire leads.
