PR3-E-18kW

THREE PHASE – ENCLOSED

This range of thyristor stack provides full seamless control of three phase resistive loads, using two thirds control technique. Signal control is by a dc signal or manual control via a 5k? potentiometer. This burst firing control stack uses fast pulse zero volts switching technology, to minimise flicker and eliminate RFI problems, it also incorporates an auto-reset temperature trip, integral semiconductor fuses and heatsink. This model, which is naturally air cooled and has easy access to signal & power terminals for simple installation.
