Product Introduction

BL-540B DC Hipot Tester adopts high frequency voltage doubler circuit, adopts advanced PWM high frequency pulse width modulation technology, closed loop adjustment, and adopts large voltage feedback, which greatly improves voltage stability. Use high-power IGBT devices and drive technology with superior performance, and adopt special shielding, isolation and grounding measures according to electromagnetic compatibility theory. The Series dc high voltage generators are made of high quality, portable, and capable of withstanding rated voltage discharge without damage. It has the characteristics of large output power and small volume, reliable over-voltage, over-current and zero-closing protection, with 0.75 times voltage switching function. It is mainly used in the power sector, industrial and mining, metallurgy, steel and other enterprise power departments to conduct DC withstand voltage test or DC leakage current test on high-voltage electrical equipment such as zinc oxide surge arresters, power cables, transformers, circuit breakers and generators.
