applications in R&D, design verification, and
production test. All nine models deliver clean,
stable and precise output power due to their
exceptionally low ripple and noise, low
temperature coefficient, excellent regulation,
and fast transient response time characteristics.
To protect your DUT (device under test), the
9170/9180 series provides safety options such
as OVP, OCP, and a key-lock feature to prevent
accidental change of parameters that might
damage your DUT. Built for reliability, the
supplies are also backed by a 3 year warranty.

External control and programming
Versatile connectivity
These power supplies offer SCPI IEEE488.2 compatible standard USB, optional
GPIB and LAN interfaces, and an optional 8-bit digital I/O and analog control
card to facilitate test system development and integration.
Test sequence execution in list mode
The list mode feature allows users to download a list of commands to the
power supply’s internal memory and execute them. A total of 150 steps can
be allocated to one of 10 internal memory locations. The test sequence can be
programmed remotely through the included application software or via the USB,
GPIB, or LAN interfaces using SCPI commands. Each step’s voltage, current,
and duration parameters can be set, with sequences configured for single or
repeated execution.
External analog programming interface
(1)
The power supplies’ output voltage and current can be controlled by either
external analog voltage or resistance. Use a 0-5 V or 0-10 V external DC
voltage source, or 0-5 kΩ variable resistor to control the output from zero to
full scale.
Application software
Create test sequences for execution in list mode via the GPIB or USB interface
using the included PC software.
eb server interface
W
(2)
The 9170/9180 series power supplies with the GPIB/LAN interface installed
provide a built-in Web server that allows users to configure, control, or monitor
he basic settings of the power supply from a remote computer using a Java-
t
enabled Web browser. Connect to the user-defined IP address to view the web
control page. SCPI commands can also be sent through the Web server interface.
Interface for controlling voltage, current, and output state
■ Create, save, and load program lists
■ View output characteristic curves and export data to a file
■ Pass/Fail test monitors maximum and minimum voltage and current values
over a specified period of time
(1) Requires card option DR1DIO or DR2DIO
(2) Requires card option DRGL
(3) Requires card option DRRS485
Control settings page for configuration of protection
and password settings for the system
Telnet interface
(2)
Power supplies can be controlled with SCPI commands via a Telnet connection
over the Ethernet interface. Any computer with a Telnet client can be used to
control the power supply.
Multi-unit control
(3)
In multi-unit control mode, up to 31 units can be daisy chained via the RS485
interface for synchronization purposes and controlled from one master unit via
the USB, GPIB, or LAN interface.

Programmable Dual-Range DC Power Supplies
9170 & 9180 series
Two power supplies in one
The 9170/9180 series provide a unique dual
range feature that offers the best of both worlds
by supplying two different ranges. Users can
select between high and low range operation for
either more voltage or more current depending
on your application, avoiding the higher cost of
buying more power than necessary.
9170/9180 Series Operating Range
Test modes for LED and other special applications
To address the growing LED market, the 9170/9180 series design incorporates special LED test modes for efficient and safe electrical tests of LED panels. Powering
LEDs with conventional power supplies will potentially cause permanent damage to the UUT or limit its lifespan due to excessive inrush current at power up and the
non-linear characteristics of the LED’s I-V curve. These power supplies feature two distinct operating modes suitable for LED testing in a manufacturing or R&D
environment and other special applications requiring a controlled rise time at power up without generating any inrush current.
LED mode
With LED mode active, inrush current will be eliminated or minimized to protect the UUT.
Inrush current
Output ON
LED mode OFF
Current flow during power up with LED mode enabled
Output ON
LED mode ON
Low current mode*
This unique function enables the power supply to
minimize the voltage rise time in a controlled
manner. This mode is used when operating at a
low current (< 1 A) and quick transitions from a
high-to-low or low-to-high voltage are needed.
