    -10 °C-- +40 °C

    Humidity:

    ≤ 85% RH

    Power Supply:

    AC 50 Hz, 220V ± 5%

     Current, voltage, waveform sampling data were obtained directly from the high pressure side, so the data is accurate.

     With over-voltage protection function. When the output voltage exceeds the set voltage limiting value, the instrument will shut down to protect, the action time is less than 20ms.

     With over-current protection: it is designed with high and low voltage dual protection. The high-voltage side will be precise shutdown protection according to the set voltage value; when the current at low-voltage side is more than the rated current, it will be shutdown protection, and the action time is less than 20ms.

     The high-voltage output protective resistors are built into the booster, so it does not need another protective resistors outside.

     As the adoption of high and low pressure closed-loop negative feedback control circuit, so the output has no capacitive rise effect.

     Advanced technology: Using digital frequency conversion technology, microcomputer controlled, boost, buck, measurement, protection and full automated testing process
     Easy to operate: Wiring is simple, fool-operation
     Comprehensive protection : Multiple protection (overload protection, high and low voltage over current protection), prompt action (action time ≤ 20ms), is a safe and reliable instrument
     Safe and reliable: the controller and high-voltage generator voltage connection via low voltage, photoelectric control, safety and reliability.

     Using a high-pressure closed-loop negative feedback control circuit, the output capacity without capacity boost effect
     Fully equipped:   LCD display, automatic storage, automatic printing
     large test range: 0.1Hz, 0.05Hz and 0.02Hz multi-frequency selection, large testing range
     Small size, light weight: very convenient for outdoors work
