Source a wide range of voltages and currents with the 360W Model 2260B-30-36 or the Model 2260B80-13 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.

Programmable DC power supplies

•t Programmable voltage or
current rise and fall times from
0.1V/s to 160V/s or 0.01A/s
to 144A/s prevent damage
from inrush current to low
impedance loads

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 priority 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 characteristic I-V curves for components such as LEDs.
