Introduce

Single-phase intelligent relay switch is an intelligent circuit protection device designed specifically for household and small commercial scenarios. It aims to monitor voltage fluctuations in real time and automatically cut off abnormal power to protect electrical equipment safety. Its core functions include overvoltage protection (power-off when the voltage exceeds the safety threshold), undervoltage protection (power-off when the voltage is too low), and automatic power restoration (automatic or manual restart after normal voltage). This product adopts wireless communication technology, supports remote control and intelligent management, significantly improving electricity safety and convenience.

Applications

  • Home distribution box: protects household appliances such as air conditioners, refrigerators, televisions, etc. from voltage fluctuations and extends their service life.
  • Small commercial premises: suitable for office, store and other scenarios, ensuring stable operation of lighting and office equipment.
  • Smart home system: As an intelligent power distribution component, it is linked with other devices to enhance overall electrical safety.

Principle

1. Voltage monitoring
The protector has a built-in voltage detection circuit that monitors the input voltage in real-time (usually 220V AC). When the voltage exceeds the set upper limit (such as 270V ± 5V) or falls below the lower limit (such as 170V ± 5V), the protection mechanism is triggered
2. Protective action
  • Overvoltage protection: When the voltage exceeds the upper limit (such as 275V), the protector immediately disconnects the circuit to prevent electrical damage due to high voltage
  • Undervoltage protection: When the voltage is below the lower limit (such as 175V), the circuit is also cut off to avoid abnormal operation of the equipment due to low voltage
  • Automatic recovery: After the voltage returns to normal, the protector will automatically reconnect the circuit within 50-60 seconds
3. Wireless communication function
The wireless protector integrates wireless modules (such as Wi Fi or Bluetooth) to transmit voltage status and action information to the user’s mobile app, supporting remote monitoring and control.
