Heat Thyristors

1-, 2-, or 3-phase power unit to 690 Vac and 1,600 A for controlling voltage applied to loads such as heating elements. Phase control, zero crossing, PID input, and local potentiometer control are standard, while RS-485 communication is optional. Applications include heaters, electrolysis, multi-zone heating, voltage-controlled devices, and dimming of high-power loads.
