CAPTEC 2-40kV/ 1000-10000J/sec

The clocked high-voltage power supply CAPTEC was especially designed for the requirements for the charge of capacitors. It is available with charging Ratings of 1.000J/sec, 10.000J/sec, 2500J/sec and 5000J/sec in nine different output voltages from 2kV up to 40kV. The charging voltage and the charging current can be adjusted independently and the actual values are read out via the analogue Interface. The charging procedure is started with the release, the voltage. After the release the charging process starts, the voltage of the charged capacitor rises linear up to the adjusted nominal value. If the nominal value for the voltage is reached, a HV-Ok signal is transmitted via the interface respectively the LED “C full” in the front plate illuminates. If the trickle charging is activated at the unit, the unit is charged if the voltage drops to an adjusted threshold. In this way, the voltage of the charged capacitor remains constant. Then the power supply recognizes if the capacitor is discharged abruptly and starts the charging process by itself.Optionally a touch panel is deliverable for the CAPTEC. The devices can be delivered with positive or with negative polarity.


Input400Vac ±10%, 50 or 60Hz, three phase
Output44 models from 2kV up to 40kV with a charge power of 1.000J/sec to 10.000J/sec. Every model is available with positiv or negative polarity. Output voltages up to 5kV are optionally available with potential-free output.
Current regulation

Load: 0,1% of full current for any voltage change.
Line: : ± 0,1% of full current over specified input range.

CoolingUp to 10 kW air-cooled> 10 kW water-cooled
InsulationUp to 20kV air-insulated> 20kV oil isolated

Analogue/digital I/O: The nominal values for output voltage, output current and output rating can be adjusted and the actual values for output voltage, output current and output rating can be read out. Additionally the release of the power element / output voltage can be set and the information about error, HV ok and cooling phase of the arc limitation can be read out.

RS232: With the RS232 interface the nominal values for output voltage, -current and -rating can be adjusted and the corresponding actual values can be read out. Additionally the release can be activated and error messages can be read out. Furtherer adjustment respectively the parameterization of the unit is possible.
