PR1-DIN-F-1.5kW Phase Burst Fire HVAC Power Controller

The PR1-DIN-F-1.5kW Phase Burst Fire Power Controller is a compact, DIN-rail mounted HVAC controller designed for precise and reliable regulation of resistive heating loads. Operating in burst fire mode, it provides efficient proportional power control while minimising electrical noise and thermal stress, making it ideal for modern HVAC and light industrial heating applications.

Engineered for professional installations, this controller incorporates advanced safety features including over-temperature protection, temperature sensor fault detection and integrated fail-safe fusing. Its compact stack design, simple clamp terminals and TS35 DIN-rail mounting ensure fast installation and long-term reliability in control panels and enclosures.

Key Features

• Burst Fire Power Control – Provides stable, efficient proportional control for resistive heating loads.

• 1.5kW Power Rating – Rated at 1.5kW (6.3A) @ 230V AC.

• Over-Temperature Protection – Automatic trip at 90°C with reset at 85°C to protect the controller and connected equipment.

• Temperature Sensor Loss Detection – LED fault indication enables rapid diagnostics and maintenance.

• DIN-Rail Mounting – Secure TS35 DIN-rail fixing allows quick installation and removal.

• Flexible Control Inputs –

  • 0–10V DC (factory set)

  • 0–5V DC

  • Manual control via 5kΩ potentiometer (not supplied)

• Integrated Fail-Safe Fuse – Ceramic quick-blow fuse fitted for unit protection and safety compliance.

• LED Status Indicator – LED intensity tracks control signal and provides clear fault status.

• Compact, Naturally Cooled Design – Optimised for vertical mounting with natural convection cooling.

Applications

The PR1-DIN-F-1.5kW is designed for precision power control in a wide range of HVAC and industrial heating applications, including:

• HVAC heating systems

• Small industrial and process heaters

• Air handling and ventilation systems

• Ovens and drying equipment

• Hot plates and thermal process equipment

• General resistive heating loads

This controller is particularly well suited to installations requiring quiet, efficient power control without remote EMC filtering.
