DMPR3-E-36kW 415V

Description

The DMPR3 series offers robust control for inductive and resistive loads, handling up to 54kW at 415V. This fully enclosed thyristor assembly provides versatile operation with user-selectable control modes—phase-angle, burst-firing, or a hybrid mode combining both. This flexibility, combined with frequency tracking from 30-80Hz, makes it ideal for installations with unstable power supplies.

The DMPR3 Thyristor Stacks are suitable for three phase 415V applications (other voltages can be accommodated). It can control loads up to 80A, with a number of control options (Potentiometer, signal, current, voltage or logic input). The stacks are assembled using the FC36M firing card giving you the option of phase angle, burst firing control or a combination of both and are fitted with Thermal cut-out trip (typically 90°C)F as an added safety feature.

Designed for easy installation, the DMPR3 features accessible internal signal and power terminals, along with integrated high-speed fuses and a heatsink for reliable performance. It is suitable for a wide range of heating, ventilation, and industrial applications, including furnaces, ovens, dryers, and air curtains, as well as inductive loads like transformers.
