Programmable DC power supplies
Source a wide range of voltages and currents with the 360W Model 2260B-30-36 or the Model 2260B-
80-13 Programmable DC Power Supplies. For higher power requirements, output up to 720W with
either the Model 2260B-30-72 or the Model 2260B-80-27 DC power supplies. All four instruments
have constant power outputs to provide a flexible range of voltage and current output combinations.
The 360W supplies can output as much as 30V or 80V or as much as 13.5A or 36A, while the 720W
supplies can output twice as much current, 72A and 27A, with the same maximum voltage outputs.
The wide range of output voltages and currents of the Series 2260B power supplies along with
multiple interfaces, enable their use in numerous applications including research and design, quality
control, and production test.
Use Series and Parallel Combinations to Extend the
Voltage Output to 160V and the Current to 216A
When more than 80V is needed, two Model 2260B power supplies can be connected in series to
double the maximum output voltage to 160V. Similarly, up to three Model 2260Bs can be connected
in parallel to produce as much as 216A. To combine the supplies in either series or parallel, they are
controlled using a master-slave configuration. The power supply defined as the master unit will show
the total voltage and current. Thus, multiple units used in combination can deliver up to 2160W to
address numerous high power applications.
Control the Voltage or Current Rise Time to Reduce
Inrush Current and Prevent Device Damage
To prevent potentially dangerous inrush currents from flowing into loads that have low resistance
when power is initially supplied, the Series 2260B power supplies have programmable rise time (or
slew rate) control. Either the voltage rise time or the current rise time can be controlled. With voltage
slew rate control, the voltage rise time can range from a slow 0.1V/s to a high speed of 160V/s for the
80V models. When operating under constant current control, the output current rise time can be
programmed from a low slew rate of 0.01A/s to a maximum value of 144A/s for the 2260B-30-72. The
programming of a current rise time puts the Series 2260B supplies in a constant current control pri-
ority mode in which the current slew rate limits the rate at which the voltage rises across the device
undertest (DUT). In addition to controlling the rise time, the fall time can also be programmed; and
the fall time values can be different from the rise time values. Thus, the delivery of power to a load
can be precisely controlled to prevent overshoot spikes and excessive amounts of inrush current. This
capability prevents damage to components, modules, or devices and will generate more precise char-
acteristic 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 supplies can have an internal resistance up
to 5.9W to simulate devices such as a lead-acid battery.

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.

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 deter-
mine 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.

Flexible and Fast for Automated Test Systems
The Series 2260B power supplies will work in any automated system
because they can interface to a controller with either a USB, LAN, or
optional GPIB interface. Furthermore, the Series 2260B supplies have fast
discharge capability to dissipate the voltage on the output quickly. These
supplies also have a fast (1ms) transient recovery time to load changes.
The combination of the fast discharge time and the fast transient response
helps minimize critical test time in automated test systems.
