Feature:1. INTELLIGENT CONTROL: The protector can set the voltage according to the power condition. The intelligent chip displays the current power voltage over the voltage and automatically breaks off2. PROTECTION OBJECT: Protector is suitable for household and similar places electrical appliances in line induction lightning strike overvoltage, operating overvoltage to protect the role3. APPLICABLE SCENARIO: Protective device is mainly used to limit the transient overvoltage amplitude, absorb, consume or discharge the inrush current energy, so that in the case of high overvoltage class, can make the protected electrical components switch from one overvoltage class to another lower overvoltage class4. ACCURATE AND FAST: Over under voltage protective device has 1% accuracy, 2 times per second speed, AC voltage 80-300V, AC current 0.1-99.9A5. DISPLAY AND INSTALLATION: Display over under voltage protector with 0.5in LED digital tube and Din rail installationSpecification:Item Type: Over Under Voltage Protective DeviceAC Voltage: 80-300VAC Current: 0.1-99.9AAccuracy: 1%Display Mode: 0.5in LED digital tubeSpeed: 2 Times per secondInstallation: Din rail.Package List:1 x Over Under Voltage Protective Device1 x User Manual
