Voltage protection device is an intelligent adjustable voltage and current protector. integrating overvoltage protection, undervoltage protection and overcurrent protection.is a microprocessor-based device for monitoring voltage and current in single-phase AC circuits. The device analyzes the power supply voltage and current, and displays its current value on a digital display. The electromagnetic relay maintains the load commutation. The permissible limits and the activation delay time are set by the user with the buttons. The values are stored in non-volatile memory
• Voltage protection device are used in administrative, industrial and residential buildings and performs the protection function:
• single-phase network from voltage surges;
• single-phase network from undervoltage/overvoltage;
• from overload currents;
• single-phase network in case of zero interruption;
• work in voltmeter and ammeter modes.
