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.
