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

The MVSS1100CDM variable fan speed controller is a sophisticated solution for precise control of 230 V single-phase tension controllable motors with maximum currect of 10 A. It features Modbus RTU communication, alarm relay output, and thermal contacts for overheating protection. It also offers remote control options, adjustable levels, and time-limited motor operation. The TK monitoring function ensures motor deactivation in case of overheating. Versatile features, including kick start, soft start, and multiple operating modes, make it a reliable choice for expert motor speed control, easily DIN-rail mounted.

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.
