Ventilation speed controller EC

The 3rd generation Fischbach EC controller ensures even more efficient control of our ventilation products with EC motors (PM motors). The extended communicative features offers the best integration into intelligent building control systems. Features of the advanced processor technology at a glance: even higher efficiency up to 40% + minimized noise level performance increase of 30% + The extended protection functions, the high flexibility (additional relay output) and the optional serial interface (RS485) shows the steady progress in the field of efficient engine technology from Fischbach. Available for all our products of series D-DS, CE, CFE, CEK – compact fans, as well as the series AW – axial fans and FLR – freewheeling impellers. The Fischbach – EC Controller is designed for speed control / regulation of Fischbach EC motors. The speed can be set with a remote setpoint (device (potentiometer), or with an external 0 – 10V control signal. The EC Controller has a + 10V – power supply for external devices. For the START / STOP function additional connections are not required, since this function works directly with the 0 – implemented control voltage – 10V. When the input voltage is less than 1V, the device is located in a STOP condition (is in STOP state). As soon as the control voltage 1V has overrun, followed by the positioning of the rotor, the start controller and the engine speed is proportional to the input signal. The sensor less operation is the motor cable only from the three phases and two wires for thermal contact. The two LED’s show the engine state or error messages are displayed. (see function tables in the assembly instructions).
