PCA-20 / PCA-25 capacitor charging power supplies are high-frequency switch-mode converters, which transform AC input to regulated high voltage DC output to charge capacitors. They were developed for the use in pumping systems of flashlamp-pumped solid-state laser devices. However, they have found their application also in non-laser medical systems, e.g. for magnetic pulse stimulators.

Maximum output power is 2000 W and 2500 W for PCA-20 and PCA-25 respectively. Several variants of modules are offered with different maximum output voltage level (Vmax), selected from 300 V to 1500 V at the moment of order. Higher output voltages are available on request. During operation an output voltage level can be chosen in working range (0 V - Vmax) by user, applying a DC voltage to the respective pin.

The actual output power depends on relation between actual operating voltage and Vmax. 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.

By default, modules are optimized for partial discharge applications. Complete discharge modifications are available on request.

Modules are intended to be used for medical purposes, in medical laser equipment. All the device parameters meet the latest versions of medical standards requirements: IEC 60601-1:2005/AMD1:2012 for electrical safety and IEC 60601-1-2:2014 for EMC, so, PCA‑20 and PCA‑25 can be used in medical systems without any modifications, any additional filtration or additional means of protection.

High reliability and efficiency, easy to integrate OEM design and a lot of flexible parameters for customized solutions allows PCA-series to be used in wide variety of applications, both medical and industrial.
