1、Multiple Protection: Digital voltage protector multiple protection functions provide protection for appliances and manually adjust the overvoltage, undervoltage and overcurrent protection values. 2、Dual Display: Digital voltage protector adopts dual display voltage, current, intuitive reading, more convenient to use. 3、Delayed Power On: Overvoltage undervoltage protector can prevent the frequent on off of unstable voltage from causing additional damage to the appliance, and achieve secondary protection. Delayed power on function, the power supply automatically recovers after 1‑600S after the voltage is stabilized. 4、PC Material And Safe: Using flame retardant PC, this protector is with overvoltage protection, undervoltage protection and voltage display (voltage measurement), the use of more safe and reliable. 5、Restore Factory Function: Our under voltage self reset overvoltage protector has the functions of reset mode selection, fault query and factory recovery. Item Type: Overvoltage Under Voltage Protector Material: PC Rated Power Supply Voltage: AC230V Rated Frequency: 50 60HZ Over Voltage (Over U) Setting Range: 230-300V Undervoltage (Lower Than U) Setting Range: 140-210V Over U And Lower Than U Tripping Delay: 0.1-30S Transmission Delay Time After Power On And Power Off: 1-600S Adjustable Voltage Measurement Accuracy: 2% (No More Than 2% Of The Total Range) Rated Insulation Voltage: 400V Output Contact: 1NO Electrical Life: 10⁵ Mechanical Life: 10⁶ Protection Grade: IP20 Pollution Degree: 3 Altitude: ≤2000m Working Temperature: -50℃-55℃ Humidity: ≤50% At 40℃ (Non Condensing) Storage Temperature: -30℃-70℃ Features 1.
