120KV200KV2mA DC High Voltage Generator

Functional features:

1, the use of new production technology and manufacturing process, citing 0 new PWM high frequency pulse width modulation technology, pulse train logic array modulation, the use of high-power IGBT components, the use of high frequency technology to improve the frequency, the frequency up to 100kHz, so that the output high voltage stability is higher, the Bowen coefficient is smaller.

2, small size, light weight, more beautiful, more reliable, easy to operate, complete functions, easy to use in the field, is currently 0 reliable products.

3, high precision, accurate measurement. Voltage and current are digital display, voltage resolution is 0.1kv, current resolution is 0.1uA. When the instrument is used, there is no need to attach a high voltage measuring instrument, and the digital voltmeter on the control box can directly display the voltage value applied to the load test. The instrument has a high and low voltage end to measure the leakage current, and the high voltage end is displayed by a circular shielded digital meter, which is not afraid of discharge impact and has good anti-interference performance, especially suitable for field use. 4, high stability of voltage regulation, smooth range voltage regulation, output voltage regulation using imported single multi-turn potentiometer, stable booster process, high adjustment accuracy, and designed with coarse and fine adjustment function. The voltage regulation degree is better than 0.1%, the voltage and current measurement error is less than 1.0%, and the pulsation coefficient is better than 0.5%. 5, negative polarity output, zero start, continuous adjustable, over voltage, over current, back to zero, ground protection, special break line protection and other protection functions. The automatic protection circuit has strong function, perfect and reliable protection, so that the operation is safe, and various technical indicators are better than the industry standard and similar products. 6, add a high precision 75%VDC-1mA function, do zinc oxide arrester measurement to bring convenience, gently press without calculation. The control box of the instrument has 75% voltage function key, when doing the lightning arrester zinc oxide test, when the current rises to 1000uA, open the 0.75 button, at this time, the value shown by the voltmeter and ammeter is 75% of the data, after completion, the boost knob should be immediately returned to zero, at the same time, the fine-adjusted voltage knob back to zero, And should immediately press the green button, cut off the high voltage and turn off the power switch. Let's do other tests. 7, convenient overvoltage setting function, using a digital dial switch, the setting voltage value can be visually displayed, so that you can operate more freely, display the value unit is kv. 8, the double pressure cylinder can be used according to the need, flexible and convenient, a multi-purpose machine, economical. 9. The bottom is provided with three built-in support feet, which increases the stability of the pressure doubling cylinder.
