What is a Capacitor Charger?
Capacitor chargers are one of OEM Tech‘s key focus areas. OEM Tech specializes in medical laser applications for surgeries and cosmetic treatments, providing medical lasers precise and reliable power sources. High efficient, precisely controlled and protected, OEM’s modules are suitable for medical systems without any modifications, additional filtration, or additional means of protection.
Capacitor chargers
A capacitor charger or capacitor charging power supply is part of a pulse power system. It provides controllable, high voltage DC output to charge capacitors that store electrical energy in a system over a long time. Later the energy can be released quickly, that is a huge amount of peak power can be delivered to a load. Such a technology is widely used in flashlamp-pumped laser systems and Intense Pulsed Light systems (IPL), but not only.
OEM Tech has designed and produces several lines of high voltage capacitor chargers with different parameters, such as: output power up to 4 kW, output voltages up to 4 kV, partial or complete discharge, 24(48)V DC or mains input voltage, compact dimensions. Capacitor chargers are suitable for industrial usage and certified for medical systems, including modules with active PFC.
These chargers include plenty of control options, making it easy to adjust the charging process. OEM prioritizes safety by incorporating protective features such as overvoltage, short circuit and open circuit protections, and a thermal protection system. Look at the comparison table showing all OEM’s models.
Besides high voltage capacitor chargers, OEM proposes several ready-to-use solutions for powering definite laser systems on a base of products, such as Holmium lasers for surgery (Ho:YAG, CTH:YAG), Alexandrite, Nd:YAG, and KTP for aesthetics, etc. See the more detailed information on the FLD-KIT developer kit page.
