Resideo AT150B1237 Transformer
The Resideo AT150B1237 Transformer is a heavy-duty 50VA step-down transformer designed for reliable power distribution in commercial and residential HVACR control systems. Engineered for versatility, this multi-tap transformer supports 120V, 208V, and 240V primary inputs, providing a consistent 27V secondary output. This wide input range makes it an essential stock item for technicians servicing various line voltage environments. As the direct replacement for PF40350, it ensures seamless compatibility during field repairs. The rugged foot-mounted design allows for stable installation within electrical cabinets or air handlers. Built to withstand the rigors of continuous duty, the AT150B1237 provides the necessary current for 24V control circuits, contactors, and thermostats. Its high volt-ampere rating prevents voltage drop-off during peak inductive loads, ensuring the longevity of downstream electronic components. For contractors looking for a reliable Resideo 50VA transformer, this unit offers the technical precision required for professional-grade installations.
Key Benefits for Technicians- Universal Primary Voltage: Field-selectable 120/208/240 VAC inputs reduce the need to carry multiple single-voltage units on the truck.
- High Power Capacity: Rated at 50VA, providing ample headroom for complex control boards and multiple zone valves.
- Simplified Retrofitting: Functionally replaces various legacy models, specifically serving as a drop-in PF40350 replacement.
- Secure Mounting: Features a durable foot-mount configuration for standard screw-down installation in control panels.
- Color-Coded Lead Wires: Includes pre-stripped, color-coded wiring to ensure accurate phase identification and faster termination.
What are the primary input wire colors for the AT150B1237?
Standard Resideo wiring usually designates White for Common, Black for 120V, Red for 208V, and Orange for 240V. Always verify with the provided wiring diagram to ensure proper phase matching.
Can this 50VA transformer replace a 40VA model?
Yes, upgrading from a 40VA to a 50VA transformer is recommended if you are adding accessories like humidifiers or electronic air cleaners that increase the total load on the 24V circuit.
Is the secondary output exactly 24V?
While often referred to as a 24V transformer, the AT150B1237 is rated for a 27V secondary output at no load to compensate for voltage drop under heavy mechanical loads, ensuring stable operation at the device level.
