Digital Voltage Protector

CNKA digital voltage protector Introduction

China Suppliers CNKA's durable digital voltage protector, backed by a 2-year warranty, has the following key features: it can quickly disconnect the power supply in the event of overvoltage, undervoltage, or overcurrent, effectively protecting electrical equipment from damage. Additionally, when the circuit voltage returns to normal, the digital voltage protector can automatically reconnect to the power supply.

CNKA digital voltage protector Feature

1  Even if the line fault voltage reaches the highest value, the protector can still operate normally without disconnecting or burning out.

2  The protector is designed to withstand fault voltage, and even at its maximum level, it will function normally without sustaining damage.

3  The product is capable of withstanding surge voltages up to 4kV.

4  Note: When connecting the product for the first time, wait approximately 10 seconds (the power-on delay time ranges from 1 second to 500 seconds, with the default being 10 seconds). The product will only start working normally once the red light goes out.

CNKA  digital voltage protector FAQ

Q: Is it still necessary to install a digital voltage protector if a residual current circuit breaker with overvoltage protection has already been installed at home?

A: In household distribution boxes, leakage protection circuit breakers are mandatory. Some users opt for leakage circuit breakers with overvoltage protection instead of separate overvoltage and undervoltage protectors to reduce the number of devices. However, this approach carries certain risks. Firstly, leakage circuit breakers with overvoltage protection typically lack undervoltage protection. Secondly, the overvoltage protection in these breakers is often fixed and provides instantaneous protection by tripping and disconnecting the line when the fixed value is reached, which may not offer comprehensive protection against all overvoltage scenarios. Therefore, a dedicated digital voltage protector may still be necessary for more complete protection.
