AC motor 10 A | differential pressure control: 0 - 2.000 Pa

MVS is an electronic fan speed controller designed for single-phase, voltage-controlled motors with a maximum current of 10 A. It regulates fan speed by changing the motor voltage using phase-angle control with Triac technology. The controller has a housing for DIN rail mounting. The motor voltage can be controlled via an analogue input or through Modbus RTU. The type of analogue input is selectable via a DIP switch, allowing for either 0-10 VDC or 0-20 mA signals. A remote start/stop command can be generated via the digital input. The minimum and maximum speeds are adjustable via internal trimmers. The device also offers various operating modes, as well as Kick start or Soft start acceleration, all selectable via Modbus RTU. The unregulated output is activated when the motor is running.

Differential pressure controller with display for fans. A typical application is Variable Air Volume flow or VAV control. The supply voltage is 24 VDC. The operating range is 0 to 2.000 Pa. It controls fan speed to maintain differential pressure or air volume flow constant at the set point. Air velocity control is also possible in combination with a Pitot tube connection set: PSET-PTX. The setpoint can be adjusted via Modbus RTU communication. The sensor output controls EC fans, frequency inverters or AC fan speed controllers via 0-10 V. Another output type can be selected if necessary. The 7-segment LED display and the four LED indicators provide a clear visual indication of the transmitter status and the controlled values. The differential pressure setpoint and all other settings can be adjusted via Modbus RTU.

This 24 VDC switch mode power supply is DIN rail mounted and features a built-in Modbus RTU repeater. It offers protection against short circuit, overload and overvoltage. The maximum load is 900 mA or 20 W. The 24 VDC supply is only available via the output channel. All devices can be connected via terminal blocks or via the RJ45 connectors. The Modbus RTU communication of both channels is reinforced by the built-in half-duplex line repeater. The supply voltage is in the range of 85 to 264 VAC (50-60 Hz). This device is mounted on a DIN rail. The enclosure offers an IP20 protection against ingress of dust.

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.
