AC motor 1,5 A | pressure control: 0 - 1.000 Pa | TK monitoring

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 1.000 Pa. It controls differential pressure or air volume flow. Air velocity control is also possible in combination with a Pitot tube connection set: PSET-PTS-200. 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.

This controller is designed for single-phase, voltage-controllable motors with a maximum current of 1.5 A. It operates on a 230 VAC / 50—60 Hz power supply and features Modbus RTU (RS485) communication. For enhanced safety, the device includes an alarm relay output and thermal contacts (TK) for motor overheating protection. The TK monitoring function automatically deactivates the motor in case of overheating. It also offers remote control and supports both kick start and soft start modes. The controller provides versatile control through an integrated ON-OFF switch and a digital input. The off level and the minimum and maximum output voltage settings are all adjustable via internal trimmers, allowing for precise control.

A 24 Volt supply module is an electronic device that converts an input voltage of 230 VAC to a 24 VDC output voltage. It is frequently used in a variety of applications, including industrial automation, medical equipment, and building automation. This switching power supply can alter an 85-264 VAC input voltage into a 24 VDC output voltage. It can supply loads up to 40 Watts. Your electrical installation is more secure because of the overload and overvoltage protection. The load can be connected using either an RJ45 connector or a screw terminal block. Due to its firm enclosure, which offers IP65 protection against the ingress of water and dirt, is the installation of this power supply in harsh environments possible. In comparison 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.
