DPF1500 SERIES

Single output

[ 2 YEAR WARRANTY ]

• Efficiency >90%

• 1500W front end

• EN61000-3-2 compliant

• 12.6 x 6.5 x 4.9 inch size

• Hot pluggable

• N+1 redundancy

• Full set of status signals

• EN55022, EN55011 conducted emissions level A

• UL, TÜV and CSA safety approvals

The DPF1500 is a 1500W 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 a single 57.8V output at full load

with a full set of status signals. The DPF1500 is designed for use as a front end in

medium power communication applications adopting distributed power architecture.

The DPF1500 provides 1500W 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, power fail, remote inhibit and current

monitoring. The DPF1500, with full international safety approval and the CE mark,

meets conducted emissions EN55022 level A. The DPF1500 can be used in

conjunction with our complete range of 3 to 200W DC/DC converters to fully configure

a distributed power system.
