Modine 5H0719560002 Transformer

The Modine 5H0719560002 Transformer is a critical OEM replacement part designed for high-performance voltage regulation in Modine unit heaters and furnaces. This 40VA HVAC control transformer efficiently steps down a 208/240V primary voltage to a stable 24V secondary voltage, providing the necessary 24-volt AC power for ignitors, gas valves, and thermostat interfaces. As the direct successor to part number 5H71956-2, this component ensures seamless mechanical and electrical compatibility during field service. Built to rigorous factory specifications, it handles the inductive loads common in commercial and residential heating systems, preventing control circuit dropouts. For technicians performing maintenance on Modine equipment, using this genuine HVAC power transformer ensures the system operates within its original design parameters, maintaining the integrity of the integrated control boards and sensitive electronic components.

Key Benefits

• OEM Direct Fit: Eliminates mounting issues and wiring discrepancies common with universal multi-tap transformers.
• Voltage Stability: Delivers precise 24V output to safeguard low-voltage control circuits and prevent relay chatter.
• Optimized 40VA Load: Specifically rated to handle the simultaneous draw of modern Modine ignition modules and diagnostic accessories.
• High-Grade Construction: Engineered to withstand the thermal stress and high-ambient temperatures found in unit heater cabinets.

Common Questions

Is this transformer a direct replacement for 5H71956-2?
Yes, the 5H0719560002 is the manufacturer-specified direct replacement for the legacy 5H71956-2 part number, ensuring identical electrical specs and footprint.

What happens if I use a transformer with a lower VA rating?
Using a transformer rated below 40VA in a system requiring it can cause the secondary voltage to sag, resulting in intermittent failure of the gas valve or system lockout under load.

Does this unit support both 208V and 240V inputs?
Yes, this dual-voltage primary transformer is designed to operate on either 208V or 240V circuits, commonly found in commercial three-phase and residential single-phase installations.
