Description
The Lennox 99W92 Class 2 Transformer is an electrical component used to step down higher line voltage to low-voltage control power for system operation. It operates on a 208/240 VAC, 60 Hz primary input and provides a 24 VAC secondary output with a 70 VA rating, supplying stable power to control circuits such as thermostats, relays, contactors, and safety components in the HVAC systems. It is installed inside of air handlers, furnaces, and rooftop units during servicing or replacement, where it ensures accurate low-voltage power distribution for consistent, safe system control in the residential and commercial applications.
