The Agilent N5700 Series
system DC power supplies
give you just the right performance — at just the right
price — in a compact (1 U)
package. This family of
affordable 750 W and 1500 W
single-output programmable
DC power supplies consists
of 24 models for simple DC
power applications. They
provide stable output power,
built-in voltage and current
measurement, and output
voltage and current from 6 V
to 600 V and 1.3 A to 180 A.
These economical supplies
offer many system-ready
features like multiple standard
I/O interfaces to simplify and
accelerate test-system development for R&D, design validation,
and manufacturing engineers
in the aerospace/defense,
automotive, component and
communications industries.
Small, High-Density Package
Saves You Rack Space
The N5700 provides up to 1500 W
in a small space-saving 1 U-high,
19-inch-wide package. Its air
vents are in the front, side and
rear (not on the top or bottom),
so you can stack other instruments directly above or below it
to save valuable rack space.

Easy Front-Panel Operation
You can quickly and easily
operate the power supply with
its rotary knobs and buttons.
Using the front-panel controls,
you can make coarse or fine
adjustments of output voltage
and current, protection settings,
and set power-on states (last
setting memory or factory
default setting). The output
voltage and current are
displayed simultaneously,
and LED indicators show
power supply status and
operating modes. You can
lock the front panel controls
to protect against accidental
power-supply parameter
changes.
Extensive Device Protection
To safeguard your device from
damage, the N5700 Series
power supplies provide overtemperature, over-current and
over-voltage protection (OVP)
to shut down the power supply
output when a fault condition
occurs. They also offer an
under-voltage limit (UVL) that
prevents adjustment of the
output voltage below a certain
limit. The combination of UVL
and OVP capabilities lets you
create a protection window for
sensitive load circuitry.
Simplify System Connections
The N5700 Series power supplies
comes standard with GPIB,
Ethernet/LAN, and USB 2.0
interfaces giving you the flexibility to use your I/O interface
of choice today and in the future.

Remote Access and Control
The built-in Web server
provides remote access and
control of the instrument via
a standard browser such as
Microsoft® Internet Explorer.
Using the Web browser, you
can set up, monitor and
operate the N5700 remotely.
Easy System Integration
and Configuration
To simplify system development,
the N5700 comes standard with
IVI-COM drivers. The N5700
supports the easy-to-use SCPI
(Standard Commands for
Programmable Instruments).
Plus it includes a compatibility
command set for the Xantrex
XFR series power supplies, the
Sorensen DLM series power
supplies and the Agilent 603x
series power supplies.
Flexible configuration: Connect
Multiple Units in Parallel and Series
Should you need greater output
power, the N5700 series power
supplies give you the flexibility
to connect in parallel up to
four similarly rated units for
greater output current and
connect two similarly rated
units in series for greater
output voltage (see output
terminal isolation information).
Analog Programming
and Monitoring
The output voltage and current
can be programmed from zero
to full scale by either an analog
voltage 0 to 5 V or 0 to 10 V
or by resis
tances of 0 to 5 kΩ
or 0 to 10 kΩ.
Universal AC input
All N5700 models have universal
AC input so they can be
automatically operated from
any AC mains input voltage
worldwide. They can be
operated
from line voltages
of 85 – 265 Vac, 47 to 63 Hz,
with no switch to set or fuses
to change when you switch
from one voltage standard to
another. They also provide
power factor correction.
Rack Mounting
The rack mount ears and
handles are provided standard
with every unit. In addition the
N5740A rack mount slide kit
makes it easy to integrate an
N5700 into a test rack by
providing all the necessary
hardware to rack mount an
N5700 series power supply
in only 1 U of rack space.
