Control the Voltage or Current Rise Time to Reduce
Inrush Current and Prevent Device Damage
Series 2260B power supplies have programmable rise time (or slew rate) control to prevent potentially dangerous inrush currents from flowing into loads that have low resistance when power is initially
supplied. Either voltage or current rise time can be controlled. With voltage slew rate control, voltage
rise time can range from a slow, 0.1V/s to a high speed of 1600V/s for the 800V supplies. When operating under constant current control, output current rise time can be programmed from a low slew
rate of 0.001A/s to a maximum value of 216A/s for the Model 2260B-30-108. Programming a current
rise time puts the Series 2260B power supplies in a constant current control priority mode in which
the current slew rate limits the rate at which the voltage rises across the device under test (DUT.) In
addition to controlling rise time, fall time can also be programmed; fall time values can be different
from rise time values. Delivery of power to a load can be precisely controlled to prevent overshoot
spikes and excessive amounts of inrush current, eliminating damage to components, modules, or
devices and generating more precise characteristic I-V curves for components such as LEDs.

Emulate the Response of a Battery
Test a circuit or device under the most realistic conditions by applying a test source with the output
resistance that is equivalent to the output resistance of the actual source that will be used to power
the circuit or device. For example, a battery has a varying internal resistance, and a device powered
by a battery will have a voltage applied to the device that is reduced by the voltage drop across the
battery’s internal resistance. Versions of the Series 2260B power supplies can have an internal resistance up to 555Ω to simulate a wide range of battery chemistries and load conditions.
10V @ 4Ω load
Internal Resistance = 0Ω
I = 2.5A
Internal Resistance = 0.9Ω
I=10V/(4Ω + 0.9Ω) = 2.04A
VLoad = 10V – (2.04A*0.9Ω) = 8.16V
Internal Resistance = 1.8Ω
I = 10V/(4Ω + 1.8Ω) = 1.72A
VLoad = 10V – (1.72A*1.8Ω) = 6.90V
Internal Resistance = 2.7Ω
I = 10V/(4Ω + 2.7Ω) = 1.49A
VLoad = 10V – (1.49A*2.7Ω) = 5.98V
Use the programmable internal resistance to simulate a battery’s output. In this example, a
Model 2260B-80-13 power supply is simulating a 10V battery whose internal resistance is 0W,
0.9W, 1.8W, and 2.7W. The resulting voltage at the output terminals drops from 10V to 5.98V
due to the voltage drop across the internal resistance of the battery.
Flexible and Fast for Automated Test Systems
With their USB, LAN, or optional GPIB interfaces, Series 2260B power supplies will work in any automated system. In addition, these power supplies have an analog control capability that can control
outputs via an external voltage and resistance. Furthermore, Series 2260B power supplies feature fast
discharge capability to quickly dissipate the voltage on the output. These power supplies also have
a fast, 1ms transient recovery time to load changes. This combination of fast discharge time and fast
transient response minimizes critical test time in automated test systems.

Create Custom Voltage Source Waveforms
An internal test sequence mode allows the Series 2260B supplies to output a set of voltage levels for
varying time intervals at each level. The test sequence can be stored and used repeatedly to determine DUT performance at number of voltage levels. In addition, the analog input control can be
used to create voltage profiles that simulate how a battery responds to a fast changing load current
requirement such as a large inrush current. Also, generate a combined DC output level with an AC
signal superimposed on it to test how a circuit responds to noise on its DC power source. The analog
input control parameter can be either a voltage input or a resistance input. With this analog control
capability, numerous types of DC supply signals can be generated to test circuits and devices under a
wide range of circumstances.
