PF40224 Replacement

The PF40224 Transformer steps down line voltage from 208/240 V (typical in HVAC systems) to 24 V for control circuits such as thermostats, relays, and control boards. Its foot-mount design allows secure chassis installation and reliable operation in heating, ventilation, and air-conditioning equipment.

PF40224 Key Features:

Input: 208/240 VAC (50/60 Hz) — accepts standard HVAC line voltage

Output: 24 VAC secondary winding rated at 40 VA (enough capacity to drive multiple control loads)

Foot-mount style with base flanges for rigid mounting to panels or chassis

Terminals: quick connect / tabbed terminals on primary and secondary sides for ease of wiring

Insulated and class-II design to meet electrical safety standards

Fits HVAC systems using Packard PF40224 or equivalents (e.g. replacing Goodman’s 0130M00138S, B1141643)
