Simple operation and complete function, easy for wild work.
Higher voltage stability, smaller ripple coefficient.
More reliable and stable, continuous short-circuit discharge directly to ground.
Intelligent grounding protection and alarm function. High precision, accurate measurement, digital display of voltmeter and ammeter, with voltage resolution 0.1kV, and current 0.1uA.
High stability of voltage regulation, smooth voltage boosting process, high adjustable precision, with coarse and fine adjustment functions. Accuracy of voltage regulation better than 0.1%, voltage and current measurement error is less than 1.0%, ripple factor better than 0.5%.
With function of high-accuracy 75%VDC-1mA, more convenient for zinc oxide lighting arrester DC testing.
HV booster is small size and large capacity, with △-Y shoring in the packing, which is portable to carry.
