EC motor | differential pressure control: 0 - 2.000 Pa

Differential pressure controller for fans generating a Variable Air Volume flow (VAV control). The supply voltage is 24 VDC. The operating range is 0 to 2.000 Pa. It controls differential pressure or air volume flow. Air velocity control is also possible in combination with a Pitot tube set. The analogue output can control EC fans, frequency inverters or AC fan speed controllers. The output type is selectable via Modbus RTU communication. The four LED indicators provide a visual indication of the transmitter status and the controlled values. The differential pressure setpoint and all other settings can be adjusted via Modbus RTU.

DIN rail mounted 24 Volt power supply module is an electrical device used to convert input voltage (typically AC mains voltage or a different DC voltage) into a stable 24 VDC (volts of direct current) output voltage and is designed to be mounted on DIN rails in electrical cabinets. This power supply delivers a 24 VDC, making it compatible with a wide range of electronic devices and systems. The device accepts an input voltage of 85–264 VAC / 50–60 Hz and the maximum load of 36 W can be connected to it. Use of the terminal block is possible for connecting the load. The supply module is protected by an IP20 enclosure and the safety of your electrical installation is increased by the overload and overvoltage protection. Some of the key sectors where this switching power supply can be used are building automation (e.g. HVAC controlling), industrial automation (e.g. providing stable power to sensors, controllers, etc.), renewable energy (e.g. solar power systems) or as laboratory equipment. Switching power supplies are comparing to the linear power supplies more efficient, lighter, and more compact (due to their transformer-free design). Because of their high efficiency, they produce less heat and contribute to greater energy savings.

Set of nozzles and PVC tubes to connect a differential pressure sensor or controller to the ductwork. It contains 2 plastic nozzles (L 66.6 mm, D 6 mm) and 2 flexible, transparent PVC tubes with a length of 2 m and a maximum working pressure of 10.000 Pa. The screws to fix the nozzles in standard ductworks are also included. This set is designed for HVAC applications and can be used in combination with differential pressure transmitters, controllers or switches.
