Medical-grade 650W AC-DC PSUs in U-channel, open-frame and enclosed

Artesyn Embedded Technologies releases its wide variety of input range, single output CNS650-M series of medical power supplies. The power supply with specification of 4 x 6 inch footprint can deliver upto 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 V, 24 V and 48 V models with a 12 V fan output and 5 V standby each. These power supplies can continuously deliver power with output of capacity across the wide temperature range of minus 40 degrees Celsius to 50 degrees Celsius and up to 80 degrees Celsius with derating.

The power supplies that are efficient carry medical and ITE safety approvals. It 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 of Type BF that is 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.

Application requires more power and the active current share facility that utilizes 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.

CNS650-M range is less than 1U high and is available in U-channel. The open-frame and enclosed end-fan options (open-frame and enclosed end-fan options currently available on 12 V model) are available. 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).
