Welcome

Thyristor Power Controller Multidrive 2PH (M2) 45A to 2700A

Ideal for: normal resistive & transformer coupled with normal resistive load types
3 wire / 24Vac to 690Vac Supply / 4-20mA or 0-10V DC linear inputs, 10K Pot or RS485 Comms input / Burst Firing, Delayed Triggering + Burst Firing

Multidrive is a fully digital and universal Thyristor Power Controller designed to drive 2 legs of 3 phase resistive & transformer load types. Available in 19 Amp sizes from 45A 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.
