Artesyn 650 Watt Open Frame Medical AC-DC Power Supplies

Capable of delivering 650 W with forced-air cooling (750 W peak) or 400 W with natural convection, the CNS650-M series follows the industry standard 4X6 inch form factor. It is available in U-channel, open-frame, enclosed and enclosed end-fan options. The series incorporates 2XMOPP and is Type BF ready, while digital communication offers control and monitoring functions.

A family of 650 watt medical power supplies, the CNS650-M series, from Advanced Energy’s Artesyn product brand is now available. Contained within an industry standard 4 x 6 inch footprint, these units can deliver 650 W with forced-air cooling (750 W peak) or 400 W with free-air natural convection cooling (650 W peak) and feature less than 500 mW no-load power consumption. The CNS650-M series is available in 12, 24 and 48 V variants, each with a 12 V fan output and 5 V standby. These power supplies can continuously deliver full output power across the wide temperature range of minus 40°C to 50°C and up to 80°C with derating.

These highly efficient power supplies carry medical and ITE safety approvals and incorporate 2XMOPP (Means of Patient Protection) to fully protect and isolate patients from the powered medical equipment. With an isolation of 4000 Vac (input to output) or 1500 Vac (input to PE; output to PE), these units are Type BF ready: for powering equipment where there is conductive contact with the patient, but not the heart, such as ultrasound monitors, blood pressure monitors, incubators, ECG equipment and operating tables.

Where an application requires more power, the active current share facility uses a signal wire to interlink two or more power supplies in parallel to increase output current capability. The built-in PMBus™ interface feature provides flexible and comprehensive digital communication via the PMBus command protocol with control and monitoring functions for voltage, current, temperature and the reporting of fault conditions.

The CNS650-M range is less than 1U high and is available in U-channel, open-frame, enclosed and enclosed end-fan options (open-frame and enclosed end-fan options currently available on 12 V model). The unit’s built-in 61000-3-2 compliant active power factor correction and Class B EMI filter deliver an EMI/RFI performance to Level B (conducted), Level B (radiated with cover).

Medical and other certifications for the CNS650-M series can be found on the product’s web page.
