Pressure/volume

Pressure/volume fan controllers
from ebm‑papst

Constant volume/constant pressure controllers provide the ability to maintain a constant set-point from a multiple EC fan array using MODBUS.

The MODBUS display & control
CN1116

The Modbus Display & Control (MDC) is a device with two RS485 Modbus ports, a keypad for setting parameters/navigating and a display to view the status of the connected fans. The RS485 Master port connects to up to 100 Modbus EC fans and the RS485 Slave port allows an interface to a higher-level Modbus Master device e.g. BMS or IoT dataloggers if required. The MDC has its own “fan auto-addressing” feature to ease installation and commissioning, and supports four different operating modes.


CN1090

Demand ventilation controller
CN1090

The demand ventilation controller (DVC) is designed specifically for industrial/commercial applications. The controller is mains powered, varies the speed of single/multiple fans and is suitable for all ebm‑papst EC 0-10V and most PWM open collector speed controllable fans.
