Product Description
Function description:
1. The data acquisition part,
1) three-phase current, collected and displayed from time to time
2) three-phase temperature, acquisition and display from time to time
3) grounding current, acquisition and display from time to time
2. The current signal part,
1) permanent open circuit fault, when the collected current value is greater than the current threshold value, * when the high current continues, it is greater than the reaction.
Time (Response time), * and the on-line current is cut off within the maximum fault time (longest Fault time) (that is, current)
When = 0), * and after the reclosing setting time, the current is still 0A, that is to say, it is a permanent open circuit fault.
Display mode: corresponding to A, B, C, led lamp, red flash once per second;
2) temporary open circuit fault, when the collected current value is greater than the current threshold value, * when the high current continues, it is greater than the reaction.
Time (Response time), * and the on-line current is cut off within the maximum fault time (longest Fault time) (that is, current)
When = 0), * and after the reclosing set time, the current value is not 0 A, that is, the temporary open circuit fault.
Display mode: correspond to A, B, C, light-emitting diode (led) lamp, and the red light flashes twice a second;
3) grounding fault, when the collected grounding current value is greater than the grounding current threshold setting value, it is grounding fault.
Display mode: corresponding to ground E, light-emitting diode (led) lamp, and the red light flashes once per second;
3. Part of the temperature signal,
Temperature fault alarm, when each phase collects the temperature value, which is greater than the temperature threshold setting value, that is, the temperature is too high to alarm.
The temperature LED lamps, flashing, and red flashing once a second, shall be provided.
4. Battery low voltage alarm, indication function,
When the battery voltage is lower than the chip operating voltage 0.1 volts, the electric alarm indication lamp shines. Flash every 3 seconds.
5. Input and remote control functions.
