How Does a Dual-Display Voltage Current Protector Work?

The working principle of a dual-display voltage current protector is straightforward yet highly effective:

Continuous Monitoring: The device constantly measures both voltage and current in real time.

Threshold Detection: Pre-set limits for voltage and current are stored in the device. These can often be adjusted based on the specific application.
