    KS-1B water level switch

    KS series water level?switch is a component designed for checking water level. According to the water level, the product will switch to different circuit to the supply/drain solenoid valve of the appliance. It has a cam to allow user choose different water level for action.

    Basic parameters and main technical performance index

      Contact capacity 10A/250VAC
      Insulation resistance The live parts and exposed non current carrying metal DC500V voltage is applied to its insulation resistance should be greater than 100MΩ
      Electrical strength The AC1500V, 50Hz voltage applied between a conductive part and non conductive part of metal continuous 1min, or AC50Hz 1875V/1s, should be no flashover or breakdown phenomenon.
    Water level Water level of action

    High water level 410mm±15mm 

    Midddle 315mm±15mm  

    Low 235mm±15mm  

    Extra low 160mm±15mm

    Water level of reset 55mm±30mm
    ater level of water flow  /
      Terminal specification 0.8mm×6.3mm
      Free fall At the height of 0.3m, for arbitrary free fall in more than 20mm thick board 3, components in any respect are not damaged, no abnormal action.
      Stable movement From the air inlet and water pressure to make the switch action 10 times in a row, measure the action level, its change value should be less than 5mm.
      Shell heat torrence V0 flame retardant
      Humidity test Place 48h 40 C 85%RH environment, electric strength test should be no abnormal, no abnormal function of products
      The life of contact No less than 25000 cycle in applying rated voltage and rated current, 6 cycles per minute.
      Environmental requirements The products and packaging are in line with the EU RoHS directive 2011/65/EU

    Using the normal work conditions

     Environmental temperature ranges from 0℃ to 50℃.Altitude can not be higher than 2500 meters.
    Comparative wetness should be less than ninety percents.(when the temperature is more than 25℃)
    There is not gas,steam,chemical deposition, dust,explosive and corrosive medium to affect the insulation in the working place.
    There is not serious vibration and bumping in the working place.
