High Voltage Power Resistors - Non-Inductive

DHVR and DHVRC series


  • DHVR - a type : 0.5W ~ 25W

  • DHVR - b, c, and d types : 30W ~ 500W

  • DHVRC High Voltage Pulse Power Resistors : up to 500W

  • DHVR is vitreous Enamel coating for better resistor protection.

  • Voltage can be up to 150kV (depending on the rated power and resistance value)

  • Standard resistance range : 100 ohm ~ 100G ohm

  • Support High Pulse Current requirement

  • Resistance value is made according to customer's application need

  • Possible resistance tolerance : +/-1%, +/-2%, +/-5%, and +/-10%

  • It can be worked at surge voltage and current applications

  • Higher resistor power can be achieved by connecting resistors in series or parallel

  • If Resistor will be immersed in high voltage insulation oil or SF6, please let us know. We support this requirement.

Applications :

High Voltage dividers

Measuring resistors

Electrostatics and medical equipment

Over voltage Protections

High Voltage Capacitor Discharge resistors

 

Please provide following working conditions :

- Resistance value and Resistor Power

- AC or DC voltage

- For Surge Voltage, please tell the peak to peak voltage range, duty cycle, repetition rate and time between two adjcent pulses.

  Application actual working / pulse voltage, resistance, pulse width, duty cycle and repetition rate can affect the resistor size.

 

The above parameters can help us offer suitable High Voltage Resistor for your application.

 

Prompt Delivery, within 1 - 3 weeks.

* Resistor sizes might vary depending on pulse voltage, load current, pulse rate and ambient temperature, etc.

** We can support lower Temperature Coefficient 50ppm, 150ppm, and 200ppm requirement.

### For a given rated power Resistor, the actual max. pulse voltage depends on the rated resistance value, pulse width, duty cycle, duration between two adjacent pulses, number of pulses per second / minute and ambient temperature. ###

For resistor power and resistance that not listed above, please contact us for details.
