Description:
The system control box for AC 380V, frequency 50HZ, power 3-22KW pump start, run, stop the whole process of monitoring and protection. The product protection technology is the basis of absorbing foreign advanced technology, integrated circuit design, with high sensitivity, reliability, and good sound and light alarm, etc. inverse time characteristics. According to the internal structure and technical parameters of different types and FQD2 into FQD1 type. FQD1 type with phase, overload, undervoltage protection, FQD2 type with phase, overload, voltage, leakage protection, and current and voltage display. Technical parameters are as follows: phase failure, the operating time <2s; overload with inverse time characteristic good; undervoltage, when the operating voltage is less than 75% of the rated voltage, the control box refused closing; leakage, leakage current> 30mA when operating time <0.1s.
