I. Purpose

Smart over-/under-voltage current protector is a comprehensive smart protector that integrates functions suchas overcurrent protection, over-voltage protection, under-voltage protection, voltage measurement, voltage display, current measurement and current display protection. In the event of overcurrent, overvoltage or under-voltagefaults, the protector can cut off the power supply instantaneously and protect the electrical equipment from beingburned out. When all lines return to normal state, the protector can automatically restore power. The overcurrent value, overvoltage value, overvoltage recovery value, under-voltage value, under-voltage recovery value, actuationtime, recovery time and power-on time of the product, functions like fault memory and inquiry and reset can be set as required. The real-time voltage value and current value are displayed cyclically. Each time you press the button"∨", the voltage or current to be displayed separately while you press the button"∧", all the alternatives canbe display. It is so flexible that it can be used as a voltmeter or ammeter. Users can choose the appropriate type ofprotector according to the actual situation.

Press "∧" or "∨" to modify the under-voltage action value, and the modification range is OFF-150V-219V; Press the button "setting" again to set the under-voltage recovery value. The upper Nixie tube displays "P 05" and the lower Nixie tube displays "180". P 05 indicates that the fifthparameter is the under-voltage recovery value, and "180" indicates the default under-voltage. The recovery value is 180V. Press "∧" or "∨" key to modify the under-voltage recovery value. When the under-voltage protection valueis adjusted to 150V, press "∨" to display OFF, indicating that the under-voltage protection is off, and thunder-voltage recovery value is modified. OFF-151V-220V, press the button "setting" again to set the under-voltage protection actuation time, the above Nixie tube shows "P06", the lower Nixie tube shows "0.1". P 06 means that the sixth parameter set is the under-voltage actuation time, "0.1" means the default overvoltage actiontime is 0.1 second, press "∧" or "∨" key to modify the under-voltage actuation time value, the modificationranges from 0.1 to 30 seconds; The default value is 0.1 seconds, and it is recommended to be ≤ 0.5 seconds. Note: After the under-voltage actuation time is set longer than 0.5 seconds, the relay cannot be driven due tothe power fault of the MCU. Therefore, when the setting time is longer than 0.5 seconds, the grid cannot be disconnected when the power is cut off.

 Press "setting" again to set the current limit parameter. The above Nixie tube displays "P 07" and the lower Nixie tube displays "63". P 07 means that the seventh parameter set is the overcurrent value, "63" means the default overcurrent protection value is 63A, press "∧" or "∨" key to modify the overcurrent protection value, modification range is 1A - 63A; Press the button "setting" again to set the overcurrent protection actuation time. The upper Nixie tube displays "P 08" and the lower Nixie tube displays "5.0". P 08 means that the eighthparameter set is the overcurrent actuation time, "5.0" means the default overvoltage action time is 5.0 second, press "∧" or "∨" key to modify the overcurrent actuation time value, the modification ranges from 0.1 to 512 seconds;the default value is 5.0 seconds. It depends on the service condition.
