Advanced Energy Industries, Inc. introduced the Excelsys™ FC1500, the industry’s first fully integrated capacitor charger and multiple output power supply. The FC1500 delivers constant charge power and eliminates the need for multiple power supplies in medical laser and Intense Pulsed Light (IPL) therapy equipment.
Conventional laser and IPL systems rely on capacitors that are charged to high voltages and then discharged to generate high-current pulses. By delivering 1500 W constant power over all charge voltages from 200 V to 1000 V, the FC1500 enables faster charging of capacitors when used at lower voltages in mixed technology systems. This helps reduce treatment times. Conventional systems also require multiple power supplies to provide high voltage inputs for capacitor charging and low voltage AC-DC conversion for system electronics such as touch panels, pumps, cooling elements and other treatments. A fully integrated capacitor charging and AC-DC power supply, the FC1500 addresses these power demands with a single unit.
“By combining a capacitor charger, AC-DC power and intelligent control, the FC1500 offers new ways for medical OEMs to design their laser and IPL systems,” said Conor Duffy, vice president of marketing, medical power products at Advanced Energy. “This unique solution provides many benefits including a 30% reduction in size, reduced weight, improved reliability, lower EMI and simplified safety certification and compliance. In addition, high levels of configurability ensure optimum solutions for any given design.”
For capacitor charging, the FC1500 can operate with large capacitance and low capacitance loads, and deliver up to 1500 W constant power (1500J/sec) with programmable charge voltages from 0 to 1000 VDC. Pulse-to-pulse stability with a repeatability of +/-0.2% is achieved through adaptive control of every pulse, while a programmable power limit enables the system to maximize the current drawn for the wall socket. A current sense signal enhances reliability by allowing the stress on the system capacitors to be accurately calculated.
For system power, the FC1500 offers a maximum power rating of 800 W and up to 10 isolated DC outputs. Field-configurable outputs provide a ‘plug-and-play’ approach to address specific application requirements. The option to connect outputs in series and parallel allows designers to support higher voltages and currents.
The FC1500 incorporates intelligent analog and digital control via the PMBus with ‘set and forget’ features and storage capabilities that enable faster time-to-market for medical OEMs. Compliant with IEC60601-1 (3rd edition) and IEC60601-1-2 (4th edition), the internal fan-cooled power supply is rated for Level 4 input surge protection, safety approved to an altitude of 3000 m and has an MTBF of over 900,000 hours.
