Product Features

High precision and accurate measurement. The voltage meter on the control box directly displays the voltage value applied to the load sample, no external voltage divider is required during use, and wiring is simple. The instrument measures leakage current at both high and low voltage ends, with the high voltage end using a circular shielded digital meter for display, which is not afraid of discharge surges and has good anti-interference performance, suitable for field use.

Voltage regulation has high stability, smooth voltage adjustment over the full range, and the output voltage regulation uses an imported single multi-turn potentiometer, ensuring a steady boosting process and high adjustment precision.

Negative polarity output, zero start, continuous adjustable, with overvoltage, overcurrent, zero return, grounding protection, and unique wire break protection functions. The automatic protection circuit is strong and reliable, ensuring safe operation.

Advanced technology and manufacturing processes are utilized, with the first application of medium frequency step-up circuitry. It incorporates new PWM high-frequency pulse width modulation technology and high-power IGBT devices, resulting in higher output voltage stability and smaller ripple coefficient.

Added high-precision 0.75UDC1mA function, greatly facilitating zinc oxide lightning arrester measurements.

The overvoltage setting utilizes a digital rotary switch, allowing for a direct and clear display of the set voltage value, with the unit of measurement being kV for easy recognition.

◆ Fault sampling employs dedicated sensors with nanosecond response times, and the optical isolation components are also nanosecond-grade, allowing for rapid and complete shutdown of the DC main circuit, thereby protecting the instrument from damage.

◆ The booster cylinder is made of new materials, lightweight and sturdy. It features three concealed support legs at the bottom, enhancing the stability of the booster cylinder. The exterior is coated with special insulating material, offering good electrical properties and strong moisture resistance.
