Multidrive is a fully digital and universal Thyristor Power Controller designed to drive most load types. ***ailable 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.
