Click image for larger view

A specialist range of single phase thyristor controllers with fieldbus communications. These controllers operate in phase angle or soft start burst fire modes and have current ratings from 80A to 250A.


Current ratings from 80A to 250A standard
Multiple feedback modes
Current limit setpoint facility
Conservatively rated at 50C ambient temperature
DeviceNet, Profibus etc. communications facility
Multiple I / O capability
True RMS measurement of current and voltage
Simple installation - compact design


This range of thyristor controllers is primarily aimed at smaller furnaces with transformer coupled heating elements. The controllers accept an analogue control signal (0-5V, 4-20mA etc) and operate in phase angle or soft start burst fire modes. Like our STC3000 3-phase series they have closed loop control of load voltage squared or power, and current limit facilities.

To make best use of these controllers the communications facilities should be used. A number of different fieldbuses are supported (see manual) which enable the setpoints to be transmitted to the controller digitally and operating status, voltages, current, power, energy etc. to be monitored. Communications also allow a more flexible set up.
