DPF1000 SERIES

Dual output

[ 2 YEAR WARRANTY ]

• 1000W front end

• EN61000-3-2 compliant

• 11 x 6.0 x 5.0 inch size

• Hot pluggable

• N+1 redundancy

• Full set of status signals

• EN55022, EN55011 conducted emissions level A

• UL, VDE and CSA safety approvals

The DPF1000 is a 1000W universal input AC/DC front end power supply in a fully

enclosed hot pluggable case with built-in fan, 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 DPF1000 is designed for use as a front end in medium

power communication applications adopting distributed power architecture. The

DPF1000 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, power fail, remote inhibit and current monitoring. The DPF1000, with full

international safety approval and the CE mark, meets conducted emissions EN55022

level A. The DPF1000 can be used in conjunction with our complete range of 3 to

200W DC/DC converters to fully configure a distributed power system.
