Product Features
Adopting intermediate frequency voltage doubling circuit, applying PWM pulse width modulation technology and high-power IGBT devices.
Adopting voltage feedback, the output voltage stability is high, and the ripple coefficient is ≤ 1%.
The full range adopts a single-chip microcontroller for smooth voltage regulation, and the boosting speed is uniformly adjustable.
● Poor grounding alarm function: If the instrument is not grounded or poorly grounded, the instrument will alarm and there will be no high voltage output.
The boost potentiometer boosts the voltage from zero.
● Specially designed zinc oxide lightning arrester test menu option, especially suitable for 0.75UDC1mA DC leakage test of zinc oxide lightning arrester
● Specially designed menu options for DC testing of power cables, allowing for one click completion of DC testing projects according to testing procedures
● Overvoltage and overcurrent can be set arbitrarily
The double pressure adopts new materials, which are lightweight and sturdy. The exterior is coated with special insulation material, which has good electrical performance and strong moisture resistance.
The product meets the technical requirements of DL/T848.1-2004 and has undergone type testing by the Electrical Equipment Quality Inspection and Testing Center of the Ministry of Electric Power, strictly adhering to the enterprise standard before leaving the factory.
It can automatically store 300 test data, print and query.
