The Artesyn Embedded Power NFS40-7908 is a versatile AC/DC converter designed for business-critical continuity, particularly in medical applications. It delivers a total power of 40W with free air convection, expandable to 50W with forced air.
The converter operates with a wide input voltage range of 85-264 VAC and features three outputs, including a main 5.1V output and two auxiliary +/-12V outputs. Key electrical specifications include ±5.0% voltage adjustability on outputs, ±0.2% line regulation for the main output, and ±2.0% load regulation for the main output. It also provides overvoltage and short circuit protection.
With an industry-standard 5.0 x 3.0 x 1.2 inch package, the NFS40-7908 is designed for 1U applications and chassis mounting. It operates within a temperature range of 0°C to 70°C and meets various EMC standards including EN55022 and FCC Part 15 Level A. Safety approvals include UL2601, CSA22.2 No. 125, and IEC601/VDE0750.
The input voltage range is 85-264 VAC or 120-370 VDC.
It provides 5.1V, +12V, and -12V outputs.
The operating temperature range is 0°C to 70°C with derating above 50°C.
Typical efficiency is 70% at 110/230 VAC.
Overvoltage protection on the +5V output (6.25 ±0.75V) and short circuit protection (continuous for single outputs, short term for multiple outputs).
Isolation is 4000 VAC input/output and 1500 VAC input/chassis.
Dimensions are 127.0mm x 76.2mm x 30.5mm (5.00" x 3.00" x 1.20").
