Product Details:

Function:

Overvoltage protection/shutdown
Undervoltage protection/shutdown
Overcurrent protection/shutdown
Continuous Overcurrent counting/shutdown
Wide voltage Overvoltage 130-300V, undervoltage 80-210V. It is always protected upon incorrect setting, and the fault lamp is on.
Rapid protection against power failure Abnormal ignition of front-end power grid, power failure, and other protector actions
Manual/ automatic recovery After manual protection turns off the output, it must be turned on manually
Knife Function When the protection function is turned off, the relay remains as it is and no longer acts, but the switch button is still active
Multi-mode display Voltage, current, frequency, visual power, etc, are switched according to mode
Setup lock Prevent the parameters from being modified mistakes, which can not achieve the purpose of protection
DC mode When DC is used, current/ power is invalid
Energy saving mode Reduce the brightness of the digital tube to save energy when the protector is not active
Embedded RTOS The system performance and stability are improved and the system has high maintainability
