Medical laser integrated capacitor charging and power conversion platform

     Advanced Energy Industries, Inc. Announced the Excelsys FC4000, a 4KJ capacitive charging unit with an integrated configurable 800W AC/DC power supply designed to power medical laser applications. The FC4000 has an efficiency of 90%, complies with IEC60601-1 (3rd edition) and IEC60601-1-2 (4th edition), and has an MTBF greater than 900,000 hours. Level 4 input surge protection has been implemented for tracking and overvoltage protection to improve reliability.

     In cosmetic and surgical lasers, capacitors generate high voltages and discharges to produce large current pulses. Traditionally, this requires a separate power source. The company was the first to offer an integrated platform that provides high-voltage inputs for capacitor charging and low-voltage AC/DC conversion for system electronics such as touch panels, pumps and cooling elements. Part of the flexiccharge family, the device extends this technological leadership with a 60% increase in capacitor charging energy to meet the needs of next-generation lasers.

     Intelligent analog and digital controls are available via the PMBus of the power supply, with "set and forget" functions and storage. This speeds time to market and can be used to simplify system maintenance and servicing. "The FC4000 further extends our leadership in power solutions for medical applications," said Emdrem Tan, Executive vice president of Power for Advanced Energy Systems. "Next generation lasers, intense pulsed light (IPL) and pulsed power systems have stringent power and performance requirements, and we will continue to innovate and deliver systems that simplify development and accelerate time to market for medical Oems."

     The device allows faster charging at lower voltages, reduces processing time, and provides up to 4KJ of constant power at charging voltages from 250VDC to 1000vdc. In addition, the capacitor charger has pulse-to-pulse repeatability from -2VD to 2VDC, while also providing up to 800W output from up to 10 isolated outputs, which can be operated in series and parallel for higher voltage and current. Using a single power supply to charge capacitors and power systems reduces application development time and complexity, reduces size and weight by 30%, and simplifies compliance with safety and EMI standards.
