- High accuracy and precious measurement. The voltage meter on the control unit can directly display voltage value of loading test object and the voltage divider is not needed to connect with external voltage divider during using and It is easy to connect the wire.The instrument can measure leakage in high/low voltage termlnal.The high voltage terminal is displayed with circle Shield digital meter, which is strong resistance to discharge shock and good ante-interference and Is suitable for filed operation
- High stability of voltage regulation, full range smooth voltage regulation . Output voltage regulation Is aaopted imported single multi-turn potentiometer, the voltage rising is smooth and adjustment accuracy Is high.
- There are various protection functions such as negative polarity output, zero-start, continuous adjustable, over voltage, over current, back to zero, ground protection, special break protection.Powerful auto protection circuit is reliable and perfect ensuring safe field operation .
- Adopting advanced technology and process manufacturing , the middle frequency voltage doubling circuit is used in the application . The new PWM high frequency pulse width modulation technology and large power IGBT are applied to output higher stability voltage and smaller ripple.
- High accuracy 0.75U function is more convenient for measuring zinc oxide arrester.
- Over voltage setting is adopted digital dial switch, which is virtually displayed by value unit kV.
- Fault sampling is adopted special senor with action time nanosecond and optical isolation element nanosecond , which can quickly turn off the main circuit ensure the maximize protection of the instrument from damage
- Booster is adopted light and rugged new material The bottom of booster Is adopt three built-in support feet to improve the solid. The insulating material on the surface of booster Is good electrical performance and moisture-proof ability.
- The case Is adopted aluminum alloy case which is small size, light weight, more beautiful, more reliable an d easy operation and full function and suitable for field operation .
