Interested
in the EPZGF-60kV/2mA ?
General information:
EPZGF series hipots is testing DC high voltage for zinc oxide lighting arrester, magnetic blowing arrester, power cables, generators, transformers, switches and other equipments, which is suitable for electric power branch, power department of factories, scientific research units, railway, chemical industry, power plants.
 
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.
