Features:

Data of current, voltage and wave form can be directly sampled at high voltage side, so the data is real and accurate;

Over-voltage protection: If the output exceeds the set limit of voltage, the instrument will shut-down to protect itself; the actuation time is less than 15ms;

Over-current protection: it is high-low voltage dual protection in the design, the accurate shut-down protection can be made according to the set value at high voltage side; If the current on low voltage side exceeds the rated current, the instrument will take shut-down protection, the actuation time are both less than 15ms;

A high voltage output protective resistor is provided in the voltage boost body in the design and this eliminates the need of additional protective resistor connected outside;

As a result of high and low voltage closed-loop negative feedback control circuit, the output without capacitive rise effect;

High-voltage control part adopts innovative light control HV switching unit, control is accurate, safe and reliable;

With color man-machine interface touch control plus controls modular software operating system, precise and intuitive;

Multi-purpose, can simultaneously measure tested objects capacitance, insulation resistance, leakage current, and AC withstand voltage test;
