Keenso Additional Undervoltage Protection with Delayed Performance for Functional Devices with Delayed Performance (40A)

1. Multiple Protections: Digital voltage protection offers multiple protection functions for devices, with manual adjustment of overvoltage, undervoltage, and overcurrent values. 2. Dual Display: Digital voltage protection provides dual display control of voltage and current, offering intuitive reading for easier operation. 3. Power Supply Dependency: Undervoltage protection prevents frequent power outages due to unstable voltage, which can cause further damage to the device. Provides secondary protection. Delayed performance for functions; power automatically recovers after 1-600 volts. 4. Safe and Secure PC Material: Uses a flame-resistant retail PC with overvoltage protection, undervoltage protection, and voltage display (voltage measurement), ensuring safe and reliable operation. 5. Restore Factory Function: Our overvoltage/undervoltage protection has reset mode selection, error query, and factory reset functions.
