The MFC series automatically control the speed of single phase voltage controllable electric motors (230 Vac - 50 Hz) according the values of multifunctional inputs (Ai1 or Ai2). These inputs can be temperature sensors (PT500) or pressure sensors (with output signal 0-10 Vdc or 0-20 mA) or other sensors with output 0-10 V or 0-20 mA (humidity, light). There is a possibility to connect this device to a BMS (building management system) interface or to use analog voltage (0-10 V) for a remote control.
The working principle of this product series is based on the so-called zero crossing detection. An optotriac combined with a microprocessor ensures flawless and accurate control where motor noises are considerably lower. There is a rotary switch to choose the working mode. When the mode is chosen, the controller will program the inputs automatically, such as temperature or analog inputs.
