Carrier HT01CN231 Transformer

The Carrier HT01CN231 Transformer is a critical power distribution component engineered for high-performance HVACR control circuits. This versatile step-down transformer features a multi-tap primary, supporting 208V, 230V, and 460V inputs, making it an essential stock item for technicians servicing diverse commercial and industrial equipment. With a 15VA power rating and a 21V to 24V secondary output, the HT01CN231 provides the stable voltage required to drive contactors, relays, and solid-state boards without the risk of fluctuating control signals. Its multi-voltage primary design eliminates the need for multiple SKUs on the truck, simplifying field replacements on Carrier, Bryant, and Payne units.

Built for durability in demanding environments, this OEM replacement transformer ensures impedance-protected operation to shield downstream low-voltage components from damage. Whether you are troubleshooting a 48TMR rooftop unit or maintaining an industrial air handler, the compact form factor and standard mounting footprint of the HT01CN231 allow for a seamless fit in tight control cabinets. Relying on genuine Carrier parts like this 15VA transformer ensures that the system maintains its original engineering specifications, reducing back-calls and labor waste caused by inferior aftermarket alternatives.

• Multi-Tap Versatility: Supports 208/230/460V primary inputs for broad application compatibility.
• Optimized Output: Delivering a reliable 21V-24V secondary to power sensitive HVACR control logic.
• OEM Precision: Guaranteed HT01CN231 fitment for specific Carrier and Bryant rooftop models including the 48SB series.
• Compact Footprint: Designed for easy integration within crowded electrical enclosures.

Is the HT01CN231 compatible with 460V systems?
Yes, this transformer is specifically designed with a 460V primary tap, allowing it to function in high-voltage industrial applications.

What happens if I exceed the 15VA rating?
Exceeding the 15VA rating can lead to excessive heat and potential failure of the control circuit. Always calculate the total VA load of all connected components before installation.

Can this replace a standard 24V transformer?
While often used in 24V circuits, this unit is rated for 21V-24V secondary output. Verify your specific control board's voltage tolerances to ensure consistent performance.
