Carrier P201-4901 Transformer

The Carrier P201-4901 Transformer is a high-capacity, multi-tap HVAC control transformer engineered for versatile primary power applications in commercial and residential systems. Designed to deliver a consistent 24V secondary output, this 100VA transformer supports heavy-duty control circuits, including multi-stage cooling and heating systems that exceed the power draw of standard 40VA units. Its multi-tap primary configuration allows for seamless integration across 120V, 208V, 240V, and 480V power supplies, making it an essential OEM replacement part for Carrier, Bryant, and Payne equipment. The robust plate-mount design and quick-connect terminals ensure a secure, high-conductivity interface for field technicians. By utilizing an industrial-grade control transformer with a 100VA rating, contractors can prevent common nuisance tripping and voltage drops in complex low-voltage circuits. This multi-tap HVAC transformer provides the reliable inductive load handling required for modern digital thermostats, relays, and contactor coils.

• Versatile Primary Voltage: Features multiple taps for 120/208/240/480V, allowing for a single SKU to cover various field requirements.
• High Power Capacity: The 100VA rating provides ample overhead for systems with high-draw accessories or multiple solenoids.
• OEM Compatibility: Specifically designed as a direct-fit replacement for Carrier-family equipment, ensuring proper impedance matching.
• Reliable Lead/Terminal Interface: Equipped with quick-connect terminals for efficient wiring and reduced installation time.
• Heavy-Duty Construction: Built to withstand the thermal demands of continuous-duty HVACR applications.

What is the purpose of the multi-tap primary on the P201-4901?
The multi-tap primary allows the technician to select the specific incoming line voltage (120, 208, 240, or 480VAC) to ensure the secondary side consistently delivers the correct 24VAC to the control system.

Can I use a 100VA transformer to replace a 40VA model?
Yes, increasing the VA rating is acceptable and often preferred in systems where additional low-voltage components have been added, as it provides more available power without overloading the transformer.

How do I handle the unused primary taps?
Technicians must properly insulate and cap all unused primary wires to prevent electrical shorts or grounding issues within the control cabinet.
