DMPR3-E-86kW, 415V Dual Mode 3-Phase Power Controller

Description 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. Key Features of DMPR3 86kW Power Controller 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.
