High Voltage Divider

The divide down ratio is determined by two resistors.

High voltage divider.

Ohm labs manufactures precision resistive high voltage dividers. A voltage divider is a simple circuit which turns a large voltage into a smaller one. The dvr series offers a 150 kv and a 300 kv ac dc model designed with precision resistor capacitor networks that provide low voltage outputs proportional to the applied high voltage input. The high voltage is applied across the divider and the divider output which outputs a lower voltage that is within the meter s input range is measured by the meter.

Written by willy mcallister. A voltage divider circuit is a very common circuit that takes a higher voltage and converts it to a lower one by using a pair of resistors. By individually characterizing each resistor in the divider voltage and power effects are minimized. It s output voltage is a fixed fraction of its input voltage.

Voltage dividers are one of the most fundamental circuits in electronics. High voltage resistances are usually 2 megohms or 4 megohms per kv to minimize heating and voltage coefficients consistent with compact sizes. Their 1000 1 and 10 000 1 ratios respectively extend the measurement capability of most digital voltmeters and oscilloscopes to 150 000 v or 300 000 v. High voltage resistor divider probes designed specifically for this purpose can be used to measure voltages up to 100 kv.

A voltage divider is a simple series resistor circuit.

The formula for calculating the output voltage is based on ohms law and is shown below. Using just two series resistors and an input voltage we can create an output voltage that is a fraction of the input.
