NR series pulse voltage dividerDetailed product description：

Product Introduction

The NR series pulse voltage divider is a device that can effectively reduce the response time of the step response of the resistance voltage divider and improve the performance of the voltage divider. It is suitable for measuring high voltage pulses. The outer shielding cover of the voltage divider is a hollow tube, and the first stage high voltage arm resistor is set in the outer shielding cover. An insulating sleeve is sleeved outside the first stage high voltage arm resistor, and a sleeve electrode is sleeved on one end of the insulating sleeve. The two ends of the insulating sleeve are supported by the high voltage arm bracket in the outer shielding cover. The high voltage input electrode is connected to the outer end of the first stage high voltage arm resistor, and the sleeve electrode is connected to the inner end of the first stage high voltage arm resistor. The first stage low voltage arm resistor is set between the bottom of the outer shielding cover and the high voltage arm bracket. Second stage high voltage arm resistor, second stage low voltage arm resistor, and output pole of voltage divider.

Product Features

1. Wide frequency range
The highest frequency can reach over 1MHz, and the peak current can reach over 20A, which is incomparable to power frequency dividers
2. Significant improvement in frequency response characteristics
The NR series digital voltage divider consists of a high voltage measurement part and a low voltage arm. In order to obtain better frequency response, a compensation circuit is added to the low voltage arm to reduce the influence of equivalent inductance and distributed capacitance on the measurement waveform when measuring impulse voltage.
3. Easy to read
With BNC interface, it can be easily connected to oscilloscopes or various recorders.
