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

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

  • It is vitreous Enamel coating for better resistor protection

  • Voltage can be up to 150kV

  • 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 application

  • 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 divider

Measuring resistor

Electrostatics and medical equipments

Over voltage Protection

Capacitor Discharge

 

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 pulses.

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

 

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

 

Prompt Delivery, within 1 - 3 weeks.

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

** We can support lower Temperature Coefficient requirement.

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