[ 2 YEAR WARRANTY ]
NFS42 SERIES
Triple output
• 6.3 x 3.9 x 1.5 package (1U applications)
• Overvoltage and short circuit protection
• 40W with free air convection
• EN55022, EN55011 conducted emissions level B
• UL, VDE, CSA and BABT safety approvals
The NFS42 series is a 40W universal input AC/DC power supply on a 6.3 x 3.9
inch card with a maximum component height of 1.5 inches for use in 1U
applications. The NFS42 series is available in three standard models with a
lower component count and larger footprint than most standard 40W models to
ensure greater reliability. The NFS42 provides 40W of output power with free air
convection cooling which can be boosted to 50W with 20CFM of air. Standard
features include overvoltage and short circuit protection. The series, with full
international safety approval and the CE mark, meets conducted emissions
EN55022 level B. The NFS42 series is designed for use in low power telecom
and industrial applications such as PABX's, industrial PC's and machine control.
