Duratech DURAPRO-12/17/21 R32 Power Supply

This genuine Duratech power supply is a replacement component for DURAPRO-12, DURAPRO-17, and DURAPRO-21 heat pump units running R32 refrigerant. The power supply unit converts incoming mains electricity to the voltages required by the heat pump’s internal electronics.

What Does the Power Supply Do?

The power supply takes the incoming AC mains voltage and converts it to the appropriate DC voltages needed by the control board, sensors, display panel, and other low-voltage electronic components within the heat pump. It provides stable, regulated power that allows these sensitive components to function reliably. Without a working power supply, the heat pump’s electronics cannot operate, even if the main electrical supply to the unit is intact.

Signs of Power Supply Failure

A failing power supply can present in several ways: the heat pump not powering on at all, the display remaining blank or flickering, intermittent shutdowns or restarts, erratic behaviour from the control system, or error codes that don’t correspond to any mechanical fault. If the unit shows no signs of life despite being connected to a working electrical supply, the power supply is a likely suspect.

R32 Model Compatibility

This power supply is specified for DURAPRO-12, DURAPRO-17, and DURAPRO-21 units using R32 refrigerant. While these models share this common component, always verify your unit’s specifications before ordering to ensure correct fitment.
