Family of affordable, autoranging system
DC power supplies
The Agilent Technologies N8900 Series provides 5, 10, and 15 kW autoranging,
single-output programmable DC power for ATE applications that require just the
right amount of performance at just the right price. The N8900 Series power
supplies’ autoranging output characteristic enables unprecedented flexibility by
offering a wide range of voltage and current combinations at full power. Power
supplies with “rectangular,” or traditional, output characteristics provide full
power at only one voltage and current combination. Just one N8900 does the
job of multiple power supplies. It’s like having many power supplies in one!
The N8900 Series provides stable output power, built-in voltage and current
measurements, and autoranging output voltage and current from 80 to 1500V
and 10 to 510 A. These supplies offer many system-ready features like multiple
standard I/O interfaces to simplify and accelerate test-system development and
compact 3U design to save rack space. If more power is required, easily parallel
multiple N8900 units to create “one” power supply with > 100 kW of total output power. The built-in master/slave control enables programming as if it’s just
one big power supply; no need to program each supply individually.

Autoranging Output – like having many power supplies in one!
Autoranging output – does the job of multiple power supplies
The N8900 power supplies’ autoranging output characteristic makes it much
more flexible than rectangular, or traditional, output characteristic power supplies because they expand the power curve, giving the user more voltage and
current combinations in one power supply. It’s like having many rectangular
power supplies in one. For example, the 1000 V, 30 A, 10 kW model is capable
of 1000 V and 10 A at 10 kW as well as 333.3 V and 30 A at 10 kW. If it were a
rectangular output, the specifications would be 1000 V, 10 A, 10 kW. At 333.3 V
it would only be able to output 3.3 kW, not the 10 kW of an autoranging output.
Figures 1 and 2 show a graphical representation of this example.

Easy front-panel operation
Using the front panel controls, you have complete access to all of the N8900
features via the extensive menu system. You can either use the voltage and
current knobs or enter your settings via the keypad. You can also set protection
settings, power-on states, and other features. The output voltage, current, and
power can be displayed simultaneously, and annunciators at the bottom of the
display show power supply status and operating modes. You can lock the front
panel controls to protect against accidental power-supply parameter changes.
Device protection
To safeguard your device, the N8900 Series power supplies provide overtemperature, over-current and over-voltage protection to shut down the power
supply output when a fault condition occurs.

Simplify system connections
The N8900 Series power supplies comes standard with GPIB, Ethernet/LAN,
USB 2.0, and analog interfaces giving you the flexibility to use your I/O interface
of choice today and safeguard your test setup for the future. There is no need to
worry whether or not you are choosing the right interface when they all come
standard. The N8900 is fully compliant with the LXI Core specification.
Remote access and control
The built-in Web server provides remote access and control of the instrument via
a standard browser. This control goes above and beyond the LXI specification,
giving users the ability to monitor and control the instrument from anywhere.
Using the Web browser, you can set up, monitor and operate the N8900 remotely.

remote access and control of the power supply
Easy system integration and configuration
To simplify system development, the N8900 comes standard with IVI-COM
drivers. The N8900 supports the easy-to-use SCPI (Standard Commands for
Programmable Instruments).
Parallel operation for more power
Need more power, we’ve got you coverd. Quickly create a master/slave setup
for even more total output power. The N8900 Series power supplies give you the
flexibility to easily connect in parallel up to seven identical units (same model
number) for greater output current. The units can also be configured to look like
“one” big power supply.
Analog programming and monitoring
The output voltage and current can be programmed from zero to full-scale by
an analog voltage signal from 0 to 5 V or 0 to 10 V. Each corresponding to 0
to 100% of full-scale. The measured output voltage and current can also be
monitored in the same way.
AC input
The N8900 has 28 total models. Fourteen have 208 VAC inputs and the
remaining 14 have 400 VAC inputs. This gives the N8900 the ability to be used
anywhere in the world. Choose 208 VAC for regions such as the Americas and
Japan or choose 400 VAC for regions such as Europe and Asia.
