Feature:1. PROTECTION OBJECT: Protector is suitable for household and similar places electrical appliances in line induction lightning strike overvoltage, operating overvoltage to protect the role2. 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 off3. MAIN APPLICATION: 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. VOLTAGE AND CURRENT: Over under voltage protector rated power supply voltage is AC220V (LN), rated power frequency for 50/60Hz, rated working current is 80A5. ACCURATE AND STABLE: The measurement error over under voltage protector is less than or equal to 1%, which is installed with EN/IEC 60715 DIN railSpecification:Item Type: Over Under Voltage Protective DeviceRated Power Frequency: 50/60HzRated Working Current: 80AMaximum Load AC: 3VAUndervoltage Operating Value: 140V-210V (factor: 175V)Overvoltage Undervoltage Operation Delay: 1-400SOvercurrent Action Delay: 1-30SLag: 5% (U.I)Power On Delay Reset Time: 1-400SMeasurement Error: 1%Mounting or DIN Rail: DIN rail EN/IEC 60715.Package List:1 x Over Under Voltage Protective Device1 x User ManualNote:Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
