Keithley Expands Programmable DC Power Supply Lines with Higher Power and Performance

Keithley Instruments, Inc., a world leader in advanced electrical test instruments and systems, announced today the new Series 2260B Programmable DC Power Supplies, which include two 360W and two 720W models. The Series 2260B family, which complements the recently introduced Series 2200 family of single- and multi-channel power supplies, is designed for benchtop, embedded, and manufacturing test applications that demand higher power and performance. Now, with the Series 2260B and Series 2200, Keithley power supplies address both low power and high power applications in research, design, QC, and production test. More information on the Series 2260B family is available at: http://www.keithley.com/data?asset=58011.

R&D, manufacturing test, and QC inspection engineers need accurate and reliable power for characterizing and debugging complex electronics and components. Unlike some popular competitive supplies that have fewer functions and less power range flexibility, the Series 2260B offers industry-leading performance and features such as programmable slew rates and battery simulation.

The 360W Model 2260B-30-36 and the Model 2260B-80-13 Programmable DC Power Supplies are capable of sourcing a wide range of voltage and currents. For applications with higher power requirements, the Model 2260B-30-72 and the Model 2260B-80-27 can output up to 720W. Depending on the model chosen, Series 2260B power supplies can source up to 80V or 72A. This wide range of output levels, combined with LAN and USB connectivity and an optional GPIB interface, makes Series 2260B supplies well suited for applications such as environmental, stress, and accelerated life test; LED and higher power component test; automotive test; battery research and test; and production test.

Programmable Rise Times Prevent Device Damage

To prevent transient voltage overshoot spikes from damaging devices under test (DUTs) when power is initially supplied, Series 2260B power supplies have programmable voltage and current rise time (or slew rate) control. The programming of a current rise time puts 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 DUT. Fall times can also be programmed independently from rise time values, so the power delivered to a load can be precisely controlled to prevent overshoot spikes, high in-rush currents, undershoot spikes, and high turn-off transients. This helps prevents damage to components, modules, or devices and allows generating more precise characteristic I-V curves for components such as LEDs. Programmable on-off delays allow turning circuits on and off at specified times to ensure power is applied and safely removed when needed.

Battery Simulation Capability

To test a battery-powered circuit or device under realistic conditions, it’s advisable to use a test source that has the characteristic performance of a battery. For example, a battery has a varying internal resistance, so a device powered by a battery will have a voltage applied that is reduced by the voltage drop across the battery’s internal resistance. Series 2260B supplies have a programmable output resistance up to 5.9Ω to simulate a battery’s internal resistance. Battery types such as lead-acid and lithium ion can be simulated for testing automotive circuits. Therefore, automotive circuits can be tested with a power supply that simulates the performance of an automotive battery.

Extend Voltage and Current Outputs with Series and Parallel Combinations

When an application demands more than 80V, users can connect two Model 2260B power supplies in series to double the maximum output voltage to 160V or connect three Model 2260Bs in parallel to produce as much as 216A. A master-slave configuration controls the supplies in either series or parallel configurations, with the master unit showing the total voltage and current. This master-slave operation means the controller must only interface with one Series 2260B power supply, which can then control the other power supplies in the system. For the highest power applications, multiple units can be combined to deliver up to 2160W.

Flexible Interface Options for Automated Test

Series 2260B power supplies offer the flexibility to interface with an automated test system via a USB, LAN, or optional GPIB interface. They also provide an analog control capability that can regulate outputs via an external voltage or resistance. With the analog input control, the Series 2260B power supplies can be used to generate complex waveforms. In addition, the analog input can be used to generate a noisy DC level to see how resistant a circuit-under-test is to noise. A fast discharge capability supports dissipating the voltage on the output quickly, so that another voltage can be programmed and generated with minimal test time delay. A fast (1ms) transient recovery time ensures rapid response to load changes. The combination of the fast discharge time and the fast transient response helps increase throughput in automated test systems.

Pricing and Availability

The list prices of the Series 2260B Programmable DC Power Supplies are as follows:

  • Model 2260B-30-36: $1420
