NFS40 and NFN40 SERIES
Single and triple output
• 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.
