High power density for conduction cooled medical PSUs

 

FiDUS Power has launched a new series of rugged, robust 450W AC/DC power supplies in the miniature 3” x 5" footprint. The use of high performance components and a reinforced double I/O isolation system suit the supplies for both industrial and medical applications.

With an extended temperature range of -40°C to +85°C (with derating), the new supplies suit space-restricted, thermally-challenging industrial applications, and medical environments where audible fan noise must be avoided. Earth leakage current is below 100μA which suits the units for BF (body floating) applications.

The new PSUs feature efficiency levels of up to 94%. Other features include 5VDC standby output, 12VDC aux output, Remote On/Off and Power Good Signal. Open frame, enclosed, end fan and top fan versions are available. They are very flexible offering a wide range of seven different output voltages from 12 to 53VDC and a +/-8% output adjustment.

Units are certified to IEC/EN/ES 60601-1 3rd edition for 2xMOPP and IEC/EN/UL 62368-1, and pass EMC compliance regulations to IEC/EN/ES 60601-2 4th edition.

Mark Gibbons, Engineering Manager at FiDUS Power commented: “Forced air cooling enables full load operation between -40°C and +50°C. This is derated to 50% load at 85°C. Natural convection-cooling will deliver 320W up to +50°C and 150W at +85°C.  Therefore, medical equipment can run in silent mode as there is no need to use a cooling fan.”

A variable fan speed controller output simplifies control if an external fan is required.
