DPF950 SERIES
Dual output
• 950W front end
• EN61000-3-2 compliant
• 12.75 x 8.0 x 4.93 inch (including panel)
• Hot-pluggable, N+1 redundancy
• Full set of status signals
• EN55022, EN55011 conducted emissions level B
• UL, VDE, CSA and BABT safety approvals
The DPF950 is a 950W universal input AC/DC front end power supply in a fully
enclosed hot pluggable case with built-in fan, front panel with handle, IEC input
connector, on/off switch and DIN output signal connector. Providing dual 48V
and 5V outputs with a full set of status signals, the DPF950 is designed as a
slot-in front end for distributed power systems. The DPF950 provides 950W of
output power and is fully compliant with EN61000-3-2. Standard features
include current sharing and full protection against overvoltage, overload and
short circuit. Remote or local system monitoring is possible via a full set of
status signals that include fan fail, DC good, remote inhibit and current
monitoring. The DPF950, with full international safety approval and the CE mark,
meets conducted emissions EN55022 level B. The DPF950 is designed for use
as a front end in medium power communication applications adopting
distributed power architecture. The DPF950 can be used in conjunction with our
complete range of 3 to 200W DC/DC converters to fully configure a distributed
power system.
