The FC1500 Medical Capacitor Charging power supply, with a built in configurable ACDC power supply is designed to provide the system power needs for Medical laser applications. The FC1500 can provide both capacitor charging and ACDC low voltage system power due to it’s unique design and intelligent control. The FC1500 can be used as a standalone capacitor charger, and if needed, various low voltage modules can be added to the unit to provide further system power. This functionality provides extra flexibility to power other systems and applications. Low voltage modules can be connected in parallel and in series for application that require higher voltage and current requirements. The Capacitor charger capabilities has the highest level of performance due the unique built in intelligent control for capacitor charging, higher charge rates and power limit control.

There is also added control and monitoring cabability via the analog and PMBus digital intelligent control system.

The combine capacitor charger and ACDC power supply design, improves end users time to market by simplifying EMI and Low leakage current approvals needed at end applications. The FC1500 also has IEC60101-1 3rd edition safety agency approval.
