PBZ-300 capacitor charging module is a high-frequency switch-mode modern and effective converter, which transforms low-voltage DC input to regulated high voltage DC output to charge capacitors. It was developed as a power supply for industrial and laboratory applications for the use in pumping systems of flashlamp-pumped solid-state laser devices and other capacitor charging applications. Compact and lightweight, it is suitable also for portable applications. Since the base modification does not feed from mains, it does not need individual certificates of compliance to medical standards, in case you want to use it in medical system, but it is possible to certify it as a part of your system.
Output power is up to 400 W for modifications with partial discharge (PD) and up to 300 J/s for modifications with complete discharge (CD). Maximum output voltage is customer defined at the moment of order in range from 300 V up to 4000 V. During operation an output voltage level can be chosen in working range (0 V - Vmax) by user, applying a DC voltage between the respective pins.
The actual output power is derated when:
- operating voltage is lower than 70% of Vmax (partial discharge modifications)
- operating voltage is lower than Vmax (complete discharge modifications)
- ambient temperature is higher than 25 °C
- input voltage is below minimum rated voltage
We would recommend to pick Vmax as close as possible to your operating voltage in order to utilize completely the output power of the device.

Many parameters of the power supply can be taylored to your needs. Some of them are listed below:
- output voltage incl. non-standard
- output polarity
- optimization for complete discharge, partial discharge or other custom regime
- reduced or bursted output power
- interfaces (calibraton, logic)
- type and location of connectors
- cables
- bench-top version of PBZ-300 with 100-240 V AC input is also available.
PBZ-[BT]-300-XXXX-YY-Z, where:
- BT means bench-top version (option)
- XXXX means maximal output voltage – user selectable from 300 V to 4000 V (300 V, 500 V, 700 V, 1000 V, 2000 V, 4000 V are the most standard modifications)
- YY means discharge type modification – CD for complete discharge modification, PD for partial discharge modification; if YY is not specified PD modification will be supplied
- Z means output polarity – P for positive, N for negative, F for floating output, B for bipolar output (three leads output). By default modifications with positive output are supplied
