High Voltage Resistors Up To 500kVRES200

If you would like to learn more about this product: Please Contact Us

Our RES200 series are highly stable, first-rate quality, High Voltage Resistors suitable for use with high impulse voltages and high frequencies.

Our 500kV Resistors

We are an industry leading high voltage resistor manufacturer and supplier and have been developing and refining our components over the years to provide a product with a very low resistance value, that starts at 0.1Ω, making these high power resistors ideal for pulsed power technologies.

Genvolt's industry-leading high voltage power tubular resistors can regulate extremely high voltages of up to 500kV and a rated power of 1000W.

High Voltage Resistors Up To 1000kV

For higher rated resistors take a look at Genvolts RES100 range of high voltage resistors. These are available with a power rating starting at 30W up to 1000W and voltage ratings from 30kV to 1000kV.
