Series 2260B
Programmable DC Power Supplies
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 resist-
ance 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
V
Load
= 10V – (2.04A*0.9Ω) = 8.16V
Internal Resistance = 1.8Ω
I = 10V/(4Ω + 1.8Ω) = 1.72A
V
Load
= 10V – (1.72A*1.8Ω) = 6.90V
Internal Resistance = 2.7Ω
I = 10V/(4Ω + 2.7Ω) = 1.49A
V
Load
= 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 0Ω,
0.9Ω, 1.8Ω, and 2.7Ω. 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 auto-
mated 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.
