2、 Product features:
(1) High precision and accurate measurement. The voltmeter on the control box directly displays the voltage value applied to the load test sample, and there is no need for an external voltage divider when using it. The wiring is simple. The instrument has high and low voltage ends for measuring leakage current. The high voltage end adopts a circular shielded digital meter display, which is not afraid of discharge impact and has good anti-interference performance, suitable for on-site use.
(2) The voltage regulation has high stability and full range smooth voltage regulation. The output voltage regulation adopts an imported single multi turn potentiometer for smooth and accurate voltage regulation during the boosting process.
(3) Negative polarity output, zero start, continuously adjustable, with various protection functions such as overvoltage, overcurrent, return to zero, grounding protection, and unique disconnection protection. The automatic protection circuit has strong functions, complete and reliable protection, and ensures safe operation.
(4) Adopting the most advanced technology and manufacturing process, we are the first to apply the intermediate frequency voltage doubling circuit. We use the latest PWM high-frequency pulse width modulation technology and high-power IGBT devices to achieve higher output high voltage stability and smaller ripple coefficient.
(5) The addition of high-precision 0.75UDC1mA function brings great convenience to the measurement of zinc oxide lightning arresters.
(6) The overvoltage setting adopts a digital dip switch that can visually display the set voltage value, with the unit of kV displayed at a glance.
(7) The fault sampling adopts a dedicated sensor with a nanosecond level action time and a nanosecond level optical isolation element that can quickly and completely turn off the DC main circuit, thus maximizing the protection of the instrument from damage.
(8) The double pressure cylinder is made of new materials that are lightweight and sturdy. There are three concealed support feet at the bottom to increase the stability of the pressure doubling cylinder. The surface is coated with special insulation material, which has good electrical performance and strong moisture resistance.
(9) The chassis is made of aluminum alloy, which is smaller in size, lighter in weight, more beautiful, more reliable, easy to operate, fully functional, and convenient for outdoor use.
