Description

The PR1 range of thyristor stacks provides full seamless
control of single phase resistive loads. 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-reset over temperature protection trip, integral
semiconductor fuses and heatsink, all enclosed. The three
models in this build include the smaller 1.5kW model and the
3kW and 6kW models in the larger enclosure. All have easy
access to signal & power terminals for simple installation.

APPLICATIONS
These are suitable for single phase ‘mains’ resistive loads.
This includes the Heating, Ventilating and Air Conditioning
(HVAC) market which would provide control applications for
battery heaters. but also for hot water tanks, heating cables
and various processing equipment.

FUNCTIONS
Over temperature protection
When heat sink temperature of above 90ºC is
detected by the sensor, the LED pulses at 0.5
second on/off intervals. The power to the load
will be disconnected and will not return until the
temperature drops to 85ºC.
Temperature sensor loss
The LED pulses at 1 second on/off intervals if
the sensor fails
