Pressure switch Dungs KS300A2-7 257843

Dungs KS300A2-7 257843 pressure switch is an adjustable differential device designed for use in air conditioning and ventilation systems. Its main task is to control the condition of air ducts, air filters and fans by controlling the electrical circuit with pressure changes in the system. For this purpose, the relay is equipped with an adjustment wheel that allows you to set the required pressure value. The package includes a Dungs KS300A2-7 257843 differential pressure switch, mounting plate, connecting hose, mounting screws, hose connections, extension pipes and installation and operation instructions. The principle of operation of Dungs KS300A2-7 257843 pressure switch is based on the reaction of the switching mechanism to changes in differential pressure: when the setpoint pressure is increased or decreased, the corresponding effect on the electrical circuit occurs. Dungs KS300A2-7 257843 pressure switch technical data: Adjustable range: 20-300 Pa Max. operating pressure: 10 kPa Pressure connection: Hose connector for hose ø 4 Ambient temperature: -15 °C to +85 °C Medium temperature: -15 °C to +85 °C Storage temperature: -30 °C to +85 °C Electrical connection: On terminal screws via cable duct M20 x 1,5 Protection type: IP 54 as specified in IEC 529 (EN 60529), optional IP 65 Setting tolerance: ± 15 % switching point deviation, relative to nominal value, with vertical mounting position.
