The complete enclosed three-phase Dual Mode Power Regulator (DMPR3) thyristor assembly provides control of inductive/resistive loads of up to 86 kW at 415V. The user-selectable control modes, via the internal switches, are either phase-angle, burst-firing, or a combination of the two i.e., start-up in phase angle and then continue in burst firing. The Single-Cycle & Dual-Cycle options offer the fastest burst rates possible, providing very accurate control and minimising Harmonic Distortion & Flicker within the system. In addition, the standard variable burst rate, adjustable from 1 to 30 seconds, is also available. There is a number of signal control options to meet most of the standard industrial requirements. All are housed in bespoke enclosures and have easy access to control signal & power terminals to aid installation. Semiconductor fuses and a heatsink with cooling fans. The controller offers a solution for many applications requiring single or dual-mode control.
