The LCH Series is designed to meet the unique requirements of medical, aesthetic and industrial pulsed energy systems. The modular design of these highly efficient and flexible devices leads to lower cost, high reliability and shorter lead times.

For years capacitor chargers have relied on resonant inverter topology to deliver constant current to the load. The design of the inverter section requires carefully matched precision components that add to the complexity and testing of the power supply.

The LCH capacitor chargers use a simpler Quasi-Constant Power (QCP) design that drastically reduces parts count and eliminates the need for costly matched components. This results in much better long term reliability and smaller size at a lower cost.
