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 100 A 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 7 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.
Comments Mark Gibbons, Engineering Manager at FiDUS Power: “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.
As with most FiDUS power supplies, free engineering samples can be delivered from stock on short lead-times, and all models are backed by the company’s five-year warranty.
