The DMPR3 86kW Three Phase Dual Mode Power Controller offers advanced control for both inductive and resistive heating loads in industrial environments. With a maximum power capacity of 86kW (120A) at 415V AC, this enclosed thyristor-based regulator allows users to select between phase-angle, burst-firing, or hybrid control modes. The dual-cycle and single-cycle burst firing options provide high-speed response, reduce flicker, and minimise harmonic distortion.
This robust controller is built for reliability, featuring semiconductor fuses, cooling fans, and a built-in soft start ramp. Its user-configurable control inputs, wide signal compatibility, and intuitive LED status indicators make it a versatile solution for demanding heating and ventilation applications.
Dual Mode Control – User-selectable phase-angle, burst-firing, or combined start-up in phase-angle with automatic switch to burst mode.
High Power Output – Capable of handling 86kW (120A) at 415V AC.
Fast Burst Options – Supports single-cycle and dual-cycle burst rates for high precision and reduced harmonics.
Soft Start Ramp – Adjustable 0–30 seconds for smooth power application and reduced inrush.
Wide Signal Input Range – Accepts 0–5VDC, 0–10VDC, 1–5VDC, 2–10VDC, 0–20mA, 4–20mA, or 5K potentiometer input.
Comprehensive Fault Detection – Alerts for phase loss, sensor loss, fuse failure, and mode mismatch with LED indication and alarm relay output.
Integrated Semiconductor Fuses – Includes 160A high-speed fuses for safety and protection.
LED Status Indicators – Visual feedback for operational status, over-temperature, and alarm conditions.
Compact Enclosure – Space-efficient and easy to install with clearly marked terminals and DIN mounting.
The DMPR3 86kW controller is ideal for a wide range of industrial heating and ventilation systems:
Industrial Furnaces
Electric Ovens
Dryers
Air Curtains
Hot Plates
Transformer Loads
Heating Cables
Other resistive and inductive load control
