Power supply for medical devices

When you need to power a medical device, one option is the OFM225. It has a 3-x-5-in. footprint and 1.5-in. height and will deliver continuous output power of 225 W at natural convection and 40º C ambient temperature, increasing to 325 W continuous at 12 CFM forced air cooling. Several units can also be operated in parallel with load sharing. Intended for type BF applications, the unit can withstand 4,000 Vac from input to both output and ground, has a leakage current of less than100 μA, and meets class B EMC requirements.

Using Powerbox one step conversion topology, where power factor correction, isolation and regulation are combined in one conversion step, the component count stays below 120. This contributes to an efficiency of 93%, zero-load power of less than 0.3 W and an MTBF of more than 500,000 h. Over-voltage, over-current and short-circuit protection with auto recovery add to operational reliability, which is enhanced by intelligent over-temperature protection regulating output power in the case of over temperature. In addition to increased life expectancy, this functionality increases the sustainability to short-term overload and reduces the risk of over-temperature shut down.

PowerboxWith a nominal input voltage of 100 to 240 V 50/60 Hz and available output voltages of 12, 15 and 24 Vdc (12 and 15 Vdc to be released later this year), the new power supplies fit nicely into a large number of medical applications worldwide.

Medline 225 OFM225 series meets, among others, safety standards IEC 60601-1 and 60950-1, EMC IEC60601-1-2, IEC61204-3, and EN55011 Class B, including corresponding North American versions. It is also RoHS, REACH and WEEE compliant.
