Product Overview

SXZGF series of DC high voltage tester is used for testing DC high voltage for zinc oxide arresters, power cables, generators, transformers, circuit breakers, switchgear and other equipments, it is suitable for electric power divisions , power department of factories and etc.

Features

♦ Light weight, more portable, full function, suitable for wild field testing.

♦ With high frequency voltage-multiplying circuit and PWM pulse width modulation technology.

♦ Small ripple coefficient, high voltage output stability, no noise, more reliable and stable.

♦ Over-voltage, over-current, zero start and fault protection function, voltage protection value can be displayed.

♦ Adapts digital display, current and voltage can be read clearly.

♦ High stability of voltage adjusting. Designed with coarse adjust and fine adjust.

♦ 75% VDC 1mA function button, convenient for Zinc Oxide arrester test.
