Technical Overview
The RE-PR3-E-xx are a range Thyristor control assemblies
that provides full seamless control of 3-phase resistive loads
of up to 36 & 54kW, using two thirds control technique. They
are controlled by a 0-5Vdc, 0-10Vdc signal or manual 5KΩ
pot.
This burst fire control assemblies use fast pulse, zero volt,
switching technology to minimise flicker and eliminate RFI
problems.
They also incorporate a temperature trip, automatic reset,
alarm output, LED 'output on' indication and heatsink.
Applications include electric heater batteries and dust heat-
ers.
Features
•
0-5Vdc, 0-10Vdc or manual 5KΩ pot control input
•
Over temperature protection with auto reset
•
No additional heatsinks required
