The United Automation PR1 range of thyristor stacks provides full seamless control of single phase resistive loads. These burst firing control stacks use fast pulse zero volts switching technology, to minimise flicker and eliminate RFI problems. 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.
Signal control is by a DC signal
Incorporate an automatic reset over temperature protection trip
Integral semiconductor fuses and heatsink with all enclosed
