Source a wide range of voltages and currents with the

360 W, 720 W, or 1080 W Series 2260B Programmable

DC Power Supplies. Choose from 12 versions with voltage output of 30 V, 80 V, 250 V, or 800 V. The 360 W versions can output current of 36 A, 13.5 A, 4.5 A, or 1.44 A; the 720 W models can output 72 A, 27 A, 9 A, or 2.88 A; and the 1080 W instruments can output 108 A, 40.5 A, 13.5 A, or 4.32 A. 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. Key Features

• 360 W, 720 W, and 1080 W versions with voltages up to 800 V and currents up to 108 A
• Programmable voltage or current rise and fall times prevents damage to low impedance loads from inrush current
• Constant current priority setting reduces voltage and current overshoot when powering LEDs
• Programmable internal resistance simulates battery output
• Choose from analog control, USB, LAN, or optional GPIB interface for automated control
• Fit six 71 mm wide 360 W units or three 142 mm wide 720 W units or two 214 mm wide 1080 W 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 potentially 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, 0.1 V/s to a high speed of 1600 V/s for the 800 V supplies. When operating under constant current control, output current rise time can be programmed from a low slew rate of 0.001 A/s to a maximum value of 216 A/s for the 2260B-30-108.

TEK.COM 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.

Precisely control voltage rise time with the variable slew rate control. 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 resistance up to 555 Ω to simulate a wide range of battery chemistries and load conditions. Flexible and Fast for Automated Test Systems With their USB, LAN, or optional GPIB interfaces, Series 2260B power supplies will work in any automated 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, 1 ms transient recovery time to load changes. This combination of fast discharge time and fast transient response minimizes critical test time in automated test systems.

Internal Resistance = 0 /uni03A9 I = 2.5 A Internal Resistance = 0.9 /uni03A9 I = 10 V/(4 /uni03A9 + 0.9 /uni03A9) = 2.04 A VLoad = 10 V – (2.04 A*0.9 /uni03A9) = 8.16 V Internal Resistance = 1.8 /uni03A9 I = 10 V/(4 /uni03A9 + 1.8 /uni03A9) = 1.72 A VLoad = 10 V – (1.72 A*1.8 /uni03A9) = 6.90 V Internal Resistance = 2.7 /uni03A9 I = 10 V/(4 /uni03A9 + 2.7 /uni03A9) = 1.49 A VLoad = 10 V – (1.49 A*2.7 /uni03A9) = 5.98 V Use the programmable internal resistance to simulate a battery’s output. In this example, a 2260B-80-13 power supply is simulating a 10 V battery whose internal resistance of the battery.

TEK.COM Series 2260B Programmable DC Power Supplies 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 determine 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. A signal generator (top plot) controls the 2260B to create a complex DC supply waveform (bottom plot) that simulates both a voltage drop due to a large inrush current and noise on the DC supply line.
