1 / 3 page GENERAL SPECIFICATIONS Hold-up time 110VAC, 40 Watts 14ms 230VAC, 40 Watts 110ms Efficiency 70% typical Isolation voltage Input/output 3000VAC Input/chassis 1500VAC Switching frequency NFS Variable NFN Fixed, 45kHz ±5kHz Approvals and VDE0805, EN60950 standards IEC950, IEC1010, UL1950 (See Note 13) CSA C22.2 No. 950 Weight 280g (9.88oz) MTBF (See Note 9) MIL-HDBK-217E 170,000 hours ENVIRONMENTAL SPECIFICATIONS Thermal performance Operating 0°C to +70°C (See Notes 8, 10) Non-operating –40°C to +85°C 50°C ambient temp., 40W Convection cooled Forced air cooling 50W @ 20CFM 50°C to 70°C ambient Derate linearly to 50% load Peak (60 seconds) 60W Relative humidity Non-condensing 5% to 80% RH Altitude Operating 10,000 feet max. Non-operating 40,000 feet max. Vibration (See Note 11) 5Hz to 500Hz, 2.4G rms peak NFS40 and NFN40 SERIES Single and triple output [ 2 YEAR WARRANTY ] • 5.0 x 3.0 x 1.2 inch package (1U applications) • Industry standard package • Overvoltage and short circuit protection • 40W with free air convection • Fixed frequency operation (NFN Series) • NFS40: EN55022, EN55011 conducted emissions level A • NFN40: EN55022, EN55011 conducted emissions level B • UL, VDE and CSA safety approvals The NFS40 and NFN40 are 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.
