Key Features:

1. Microprocessor-Based Voltage Monitoring

   • The device uses a microprocessor to monitor the main voltage in real-time, providing accurate readings of voltage and current on a digital display.
   • • Over and Under Voltage Protection

       • Protects equipment by disconnecting power when the voltage exceeds or drops below the user-set threshold, preventing damage from surge or low voltage conditions.
       • • Adjustable Voltage and Time Delay

           • The user can set both the voltage value and delay time for over-voltage and under-voltage protection, allowing for customizable protection settings.
           • The device stores these settings in non-volatile memory, ensuring they are retained even after power loss.
           • • Electromagnetic Relay for Load Switching

               • The load is switched by an electromagnetic relay, ensuring reliable and fast switching to protect connected devices.
               • • Current Display

                   • Displays real-time current readings, allowing users to monitor the current flowing through the circuit.
