Features:This pressure controller is specially used forwater pump automatically turn on/off.Default pressure range is 0.14-0.28Mpa, if pressure<0.140.02MPa,controller is connected; if pressure>0.280.02MPa, controller is disconnected.The upper and lower threshold of the switch pressure can be adjusted within the adjustment range.Controller has 2 springs to adjust pressure threshold, easy to adjust and accurate.It will automatic turn on pump when pressure is less than the set threshold of switch, and automatically turn off pump when pressure is more than set threshold.Specifications:Rated Voltage: 220VACRated Current: 10A ACRated Isolation VoltageUi: 380VRated ConditionalShort-Circuit Current: 1000AFuse Model for Rated ConditionalShort-Circuit Current Test: RL6-10/25AConventional Thermal Current Ith: 10AThread Size: ZG1/4(internal andexternalSet Pressure: 0.14-0.28MpaSize: 10*9.5*7cm/3.9*3.7*2.7inWeight: 356g(approx.)Installation Note:1. When installing this pressure controller,the connection thread should be well sealed without water leakage; otherwise itmay cause motor frequent turning on and off and eventually burning-out.2. Wire inlet and outletshould be well fixed, in order to prevent any wire damage.Package Includes:1 x Switch.
