NFN40

The NFN40 is industry standard 40 Watt power supplies with the capability to supply 50W in a forced air ambient and to automatically operate from any voltage between 85VAC and 264VAC. Use of MOSFET based switching circuits allows for enhanced features such as output regulation down to zero load (NFN40). Universal input voltage eliminates the need to change jumpers or switch settings to cater for different or widely varying line voltages.In addition to the input voltage range, VDE, UL, CSA, EN60950 and IEC950 approvals make the NFS40 and NFN40 ideal for use in equipment installed throughout the world. The fixed frequency operation of the NFN40 further reduces emissions below VDE class B and significantly reduces leakage current.These low profile switchers with high power density are intended for use in small, digital systems.

Features of the NFN40 are:(1)5.0 x 3.0 x 1.2 inch package (1U applications); (2)Industry standard package; (3)Overvoltage and short circuit protection; (4)40W with free air convection; (5)Fixed frequency operation (NFN Series); (6)NFS40: EN55022, EN55011 conducted emissions level A; (7)NFN40: EN55022, EN55011 conducted emissions level B; (8)UL, VDE and CSA safety approvals.

The absolute maximum ratings of the NFN40 can be summarized as:(1)Thermal performance Operating: 0°C to +70°C; (2)(See Notes 8, 10) Non-operating :40°C to +85°C; (3)50°C ambient temp., :40W
