Advanced Energy / Excelsys CS1000 Fanless Power Supplies

Advanced Energy / Excelsys CS1000 Fanless Power Supplies are highly efficient, 1000W, single-output, convection-cooled power supplies that eliminate acoustic noise, vibration, and the need for baseplate cooling. The CS1000 power supplies offer a variety of features for increased performance, efficiency, and reliability for mission-critical applications. The lightweight power supplies are suited for use in a wide range of medical treatment applications, as well as vibration-sensitive clinical, diagnostic, and industrial applications. The CS1000 series offers conversion efficiencies of up to 94%, as well as a 24W bias supply voltage of 5V or 12V. The power supplies are available with 24V or 48V single outputs, operate off universal AC input voltage of 90VAC to 264VAC, and come in a compact 1U package.

The devices provide intelligent analog and digital control and monitoring with PMBus. Control and monitoring features include AC fail, global remote/off, output voltage/current control, and protection features, such as overvoltage, overcurrent, short circuit, and overtemperature.

The CS1000 devices are available in M and S versions. The CS1000M is certified for IEC 60601-1 3rd edition and IEC 60601-1-2 4th edition (EMC) for medical applications and provides 2x MOPP, 4kVAC primary to secondary isolation, as well as <300μA leakage current. The CS1000S carries IEC 60950 safety approvals and is also certified for the IEC 62368-1 safety standard for industrial applications.
