HV CONCEPT

CCR SERIES

You can choose your own full scales (Vmax and Imax) even if these values are not available in standard. For example, you can get a 3750 V generator based on 750 J/s model. In this case, you will get an output voltage adjustable from 0 to 3750 V and an output current from 0 to 0.4A.

ABOUT THE CAPACITOR CHARGER

The Capacitor charger (CCR) can be considered as a current generator (Norton model).

He's suitable for all applications that need very fast regulation with big voltage amplitudes and repeated charging and discharging (total or more than 50% of the max). 


The CCR has a very low stored energy and may hold a shoting rate up to 1kHz*. CCR machine must operate with an essentially capacitive load. Its regulation mode differs from a SR and prevent from any overshot. 
Using a CCR as a Regulated power Supply is not recommended.

Overview

  • Compact & industrial design

  • Low stored energy

  • Voltage & current outputs continuously adjustable from 0 to 100%

  • Voltage & current setting & monitoring from front panel or remote interface

  • Customized voltage & current* with no extra cost

  • High reliability & efficiency

  • High precision regulation

  • Total protection against arc, overload, short circuit & over temperature

  • Automatic regulation crossover

  • Over current limitation

  • Remote, inhibit & interlock functions

  • 3 ½ digit display with polarity display

  • Double resonance technology (ZVC)

  • Safety switch key

  • Air cooling

  •  2 years warranty

description ccr series

High voltage CCR models are designed to charge high voltage capacitors and Marx generators They operate as constant current sources. 

The numerous advantages of compactness, robustness, reliability, and saving offered with the double resonance technology are already available on these models which constitute the low end range. 

Five series of chargers are offered: 150J/s, 300J/s, 600J/s, 750J/s and 1.5kJ/s. These chargers are all based on a 3U and 5U height 19’’ rack presentation. Using a modular design, our products integrate the latest technology components. Above 20KV, HV blocks are in resin.
