Multidrive is a fully digital and universal Thyristor Power Controller designed to drive most load types. Available in 21 Amp sizes from 35A to 2700A the Multidrive provides the user with optimum control of the process and ease of set-up & maintenance. The Front panel keypad & display allows total flexibility for the user with full configuration of the process & digital inputs types and firing & control modes, to suit the application. Real time values such as the Voltage, Current & Power can be read from the display. Internal quick-blow fuses as standard provide complete protection for the thyristor. Additional features such as current limit, profiling, heater break alarm and RS485 comms come as standard.
