Reznor 39095 Transformer

The Reznor 39095 Transformer is a heavy-duty 200VA control transformer engineered for multi-tap versatility in commercial and industrial HVAC applications. Designed to handle high-demand control circuits, this unit effectively steps down 460V, 230V, or 208V primary voltage to a stable 24V secondary output. This high VA rating ensures the transformer can simultaneously power multiple loads, including ignition modules, contactor coils, and sophisticated digital controllers, without the voltage sag often seen in undersized 40VA or 75VA alternatives.

For service technicians, the Reznor 39095 provides a reliable solution for maintaining low voltage control system integrity in unit heaters and rooftop systems. Its robust construction is purpose-built to withstand the thermal stressors found in furnace cabinets, ensuring consistent HVAC 24V power supply performance. When replacing a failed step-down transformer, this OEM Reznor part ensures precise electrical compatibility and physical fitment, eliminating the need for field modifications or bracket adjustments common with universal multi-tapped units.

Key Benefits

• Multi-Tap Primary Flexibility: Accommodates 208V, 230V, and 460V inputs, making it a versatile stock item for various commercial line voltages.
• High Power Capacity: The 200VA rating supports complex control loops and multiple solenoid valves without overheating.
• OEM Precision: Guaranteed Reznor equipment compatibility for seamless integration into existing unit heater wiring harnesses.
• Industrial Durability: Constructed with high-grade laminations and copper windings to reduce humming and electrical noise in the 24VAC control circuit.

Common Questions

Can I use this transformer to replace a lower VA rated unit?
Yes, a 200VA transformer can safely replace a 40VA or 75VA unit as long as the primary and secondary voltages match. The higher VA capacity provides a larger safety margin for the HVAC control system.

How do I wire the primary side for different voltages?
The primary side features specific leads or terminals for 208V, 230V, and 460V. Always verify the incoming line voltage with a multimeter and cap off any unused leads to prevent shorting against the cabinet.

What are the signs that a 24V transformer has failed?
Common indicators include a lack of 24VAC at the secondary terminals despite having line voltage at the primary, scorched windings, or a distinct "burnt" electrical odor during troubleshooting.
