This PR3 thyristor stack provides full seamless control
of three phase resistive loads up to 180kW, using two
thirds control technique. Signal control is by a DC
signal. These burst firing control stacks use fast pulse
zero volts switching technology, to minimise flicker and
eliminate RFI problems. They also incorporate an
automatic resetting temperature trip, integral
semiconductor fuses and heatsink. All are forced-air
cooled and have easy access to signal & power
terminals for simple installation.
Suitable for the Heating, Ventilating and Air Conditioning
(HVAC) market for air curtain applications, but also for
furnaces, ovens, dryers and hot plates
