AC motor 2,5 A | air volume flow control

Exceptionally quiet fan speed control for single-phase motors. The (combined) maximum motor current is 2,5 A. AC fan speed can be adjusted remotely via the analogue input or via Modbus RTU communication. The analogue input type is selectable. The fan speed is controlled by varying the motor voltage via Pulse Width Modulation - IGBT technology. The TK monitoring function disables the motor in case motor overheating is detected. The supply voltage is 110-240 VAC / 50-60 Hz. A remote start - stop command can be generated via the digital input. No configuration is required - easy to use! Extra silent motor operation is guaranteed thanks to the technology used!

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.

A 24-volt switched-mode power supply (SMPS) is a type of electronic power supply that converts electrical energy from one voltage level to another. This supply module with the convenience of DIN rail mounting is a versatile solution for various applications across different industries. Whether you're managing automation systems (e.g. heating or ventilation systems), control panels, or electronic devices, this power supply is the key to your reliable and secure operation. This module accepts an input voltage of 85–264 VAC / 50–60 Hz. The maximum load on this switched mode power supply is 40 Watts. The loads can be connected via the terminal block or via the RJ45 connector. Because it is designed to be mounted on a DIN rail, integrating the power supply into your electrical cabinet will be simpler. The device is shielded from dust and dirt by the IP20 protection provided by the enclosure. In addition, the safety of your electrical installation is increased by the overload and overvoltage protection. Comparing to linear power supplies, switching power supplies are 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.

Motor maintenance switch with padlockable OFF-position. It can be used to ensure safe working conditions while performing maintenance tasks and to cut a motor off from the electrical grid. The (combined) maximum load is 3 kW. The forced open contacts fulfil load break requirements up to 690 VAC. This makes them also suitable as motor emergency-OFF switches or as enclosed main switches for individual electrical loads. The switchgear is housed in a moulded enclosure with an IP65 sealing. This switch has 2 poles and one normal open and one normal closed auxiliary contact. Manufacturers code: Kripal UKPN1-2P20A/11
