Fan Speed Controllers

ebm-papst DVC Demand Ventilation EC Fan Controller Demand Ventilation Controllers are designed for for both industrial and commercial applications. The DVC requires mains power offering single/multiple fan speed controller and is compatible with all ebm-papst EC 0-10V and most PWM open collector speed controllable fans. Switched Live and Volt Free inputs: Stop / Run control, Fan Speed/ Set point select input. Alarm output for fail, Solid state relay 60V/ 0.1 A. 0-10V Sensor input connections, 24V DC Sensor Supply output, One or Two Sensors. Proportional Band Control set-points for up to two sensors. Closed loop PID control set-points. Selectable either Simultaneous or alternative fan run, selectable change over period, selectable single fan use. Tachometer Monitoring up to two fans, control of 1-24 fans per controller, maximum 12 fans per 0-10V PWM output. BMS remote enable input.

ebm-papst Manual 0-10V EC Fan Controller with Display Suitable for use with the full range of ebm-papst EC fans the RM-ECd controller provides infinitely variable, manual speed control between 0% and 100%. The control voltage 0-10V is displayed on the LCD for ease of commissioning. RPM can be displayed if a tacho fan is used. Powered by 10V DC output from the motor. Can Control multiple fans running at the same speed. Infinitely variable speed setting. LCD screen showing 0-10V or RPM. Pulses / rev selectable using DIP switch. Cable entries 4 x M16 or M20. 4mm mounting holes. No separate power supply required.
