Hgp6908 series and hg6910 series switching power supplies are the second generation of high voltage and high current switching power supplies of our company. Compared with the general switching power supplies, they are equipped with voltage setting display function (that is, the set maximum charging voltage can also be seen in the current limiting state) and overvoltage protection value voltage setting display function. Moreover, it also has the high-power output characteristics of high output voltage and large output current. The output current and voltage can be set arbitrarily, which has strong flexibility.
It is suitable for sophisticated charging of various specifications of electrolyte capacitors and bile electrolytic capacitors, and has good electromagnetic compatibility. It has overvoltage and short-circuit protection functions, which well protects the instruments and operators.
Performance characteristics:
1. Low power consumption: low switch loss and high transformer utilization.
2. High conversion efficiency: the switching tube works in the switching state, and its conversion efficiency can reach 85% ~ 96%. Compared with the linear power supply, the power consumption cost is saved by about 50%.
3. Small size and light weight, about 15kg,
4. Safe and reliable: when the voltage stabilizing circuit, high-voltage circuit, overvoltage, load and other faults or short circuits occur, it can automatically stop working, and its protection function is sensitive and reliable.
5. Front and rear panel output, convenient for staff operation.
6. The instrument has its own discharge function.
