Source a wide range of voltages and currents with the 360W, 720W, or 1080W Series 2260B
Programmable DC Power Supplies. Choose from 12 versions with voltage output of 30V, 80V, 250V
or 800V. The 360W versions can output current of 36A, 13.5A, 4.5A, or 1.44A; the 720W models can
output 72A, 27A, 9A, or 2.88A; and the 1080W instruments can output 108A, 40.5A, 13.5A or 4.32A.
This wide range of output voltages and current, combined with multiple interface choices, makes
the Series 2260B ideal for use in a wide range of applications, including research and design, quality
control, and production test.
• Choose from analog control,
USB, LAN, or optional GPIB
interface for automated control
• Fit six 71mm wide 360W units
or three 142mm wide 720W
units or two 214mm wide
1080W units in a standard rack
width to minimize bench and
test system space
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 potential-
ly 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 oper-
ating 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.
