High Voltage Resistors Up To 1000kV

The Genvolt RES100 range of High Voltage Resistors are available with a rated power from 30W up to 1000W with voltage limits between 30kV and 1000kV, depending on the application use required.

We have been manufacturing high voltage resistors for a long time and over those years we have perfected our design and manufacturing processes enabling us to supply one of the best HV resistor products on the market today.

What design features do the HV Resistors have?
The Genvolt power resistors are of tubular design to give them a low temperature coefficient that makes them capable of dissipating the electrical power (Watts), that has been converted into heat, with considerable efficiency and their high stability allows for proficiency in providing accuracy in load balancing and measurement.

What is the maximum temperature rating?
All of our high voltage resistors are dip coated in Silicone resistance paint and have a maximum temperature rating of 300°C.

Where can they be used?
Our power resistors are designed for usage in a diverse range of demanding applications including:

  • Medical Equipment
  • Power Supplies
  • Capacitor Discharge
  • ESD Protection
  • RADAR Equipment
  • X-Ray Systems
  • Test Load
  • Test Equipment
  • The Measurement of High Voltage Divider Applications
  • Restricting the Current Flow in a High Voltage System
