Product Detail

Product Features

1.This product features an LED display that shows real-time grid voltage and current values.

2.Protection parameters including overvoltage, undervoltage, overcurrent, and time delay can be configured locally. The device also includes a configuration menu and functions such as one-touch restoration to factory settings. When the product is in the "No Output (OFF)" state, press and hold the ON/OFF button for 5 seconds to restore factory settings.

3.The product also has rapid disconnection capability. When the overvoltage level reaches 320V or the undervoltage level drops to 110V, the device automatically enters rapid disconnection mode, cutting off the load within 0.1 seconds.
