The Artesyn Embedded Technologies NFS40-7924 is an open frame AC/DC converter designed for reliable power delivery in critical applications. It provides a single 24V output with a maximum current of 1.6A, delivering up to 40W of power under free air convection and 50W with forced air.
This converter operates with a wide input voltage range of 85-264 VAC and features universal input capability. Its efficiency is rated at 70% typical. The NFS40-7924 is built with essential protections including overvoltage and short circuit protection. It also boasts high isolation voltage of 4000 Vac between input and output.
Designed for demanding environments, the NFS40-7924 operates within a temperature range of 0°C to 70°C with derating. Its compact dimensions of 127.0mm x 76.2mm x 30.5mm make it suitable for 1U applications. The unit is specifically approved for medical applications and meets various EMC standards including EN55022 and FCC Part 15 Level A.
Key electrical specifications include line and load regulation, with main output line regulation at ±0.2% and load regulation at ±2.0%. Voltage adjustability is ±5.0% for the main output. The converter also features a hold-up time of 18ms at 110 VAC and 132ms at 230 VAC. It is designed for chassis mounting.
The input voltage range is 85-264 VAC or 120-370 VDC.
It provides a 24V output at 1.6A maximum, with 40W total power in free air convection and 50W with forced air.
The operating temperature range is 0°C to 70°C with derating; the non-operating range is -40°C to +85°C.
It uses an open-frame chassis-mount package measuring 127.0mm x 76.2mm x 30.5mm.
Isolation is rated at 4000 Vac between input and output and 1500 Vac between input and chassis.
Hold-up time is 18 ms at 110 Vac and 132 ms at 230 Vac.
Safety approvals include UL2601, CSA22.2 No. 125, and IEC601/VDE0750.
