CS1000 Series


Innovative, Fanless, 1U, High Efficiency, 1000 W, Single Output Power Supplies

The CS1000 fanless power supplies deliver up to 1000 W with natural convection cooling. Available with 24-V or 48-V single outputs, the CS1000 operates off a universal AC input voltage of 85 to 264 VAC. The series provides intelligent analog and digital control and monitoring with PMBus® (an open-standard digital power management capability). Control and monitoring features include AC fail, global remote/off, output voltage/current control as well a large suite of protection features, such as over-voltage, over-current, short-circuit, and over-temperature.

The CS1000M is certified for IEC60601-1 third edition and IEC60601-1-2 fourth edition (EMC) for medical applications. It also provides 2xMOPP, 4K VAC primary to secondary isolation as well as <300 uA leakage current. The CS1000S carries IEC60950 safety approvals and is also certified for the upcoming IEC62368-1 industrial safety standard.
