Artesyn Launches New Family of Medical 650 Watt AC-DC Power Supplies
Artesyn Embedded Technologies today announced its new wide input range, single output CNS650-M
series of medical power supplies. 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 V, 24 V 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 degrees Celsius to 50 degrees Celsius and up to 80 degrees
Celsius 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 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).
