Keithley 2260B-80-27 Power Supply
Rent Keithley Programmable Dual Channel DC Power Supply, Two 80V, 27A, 720W
The Keithley 2260B-80-27 is a cutting-edge Programmable DC Power Supply, boasting an impressive output capability of 720W. Designed to meet diverse high-power requirements, this power supply can source a broad spectrum of voltages and currents, with a maximum current output reaching up to 27A at 80V. The flexible power output features allow for a constant power mode that delivers a range of voltage and current combinations to suit various applications such as research and development, quality control, and production testing.
For scenarios where more than 80V is required, multiple Keithley 2260B supplies can be connected in a series configuration to achieve a combined output voltage of up to 160V. Similarly, connecting up to three units in parallel can yield a maximum output of 216A. The master-slave control configuration allows for combined supplies to operate seamlessly, with the master unit displaying the total voltage and current delivered, enabling up to 2160W of power to be effectively managed for demanding applications.
Equipped with programmable rise time (or slew rate) control, the Keithley 2260B efficiently manages inrush currents that may occur with loads possessing low resistance. Users can adjust the voltage rise time anywhere from a gradual 0.1V/s to a swift 160V/s. When operating under constant current control, the output current rise time is programmable from 0.01A/s to a maximum of 144A/s. This feature not only prevents overshoot spikes, but also minimizes excessive inrush currents, safeguarding sensitive components and providing precise characteristic I-V curves, especially for components like LEDs.
The Keithley 2260B-80-27 also simulates real-world conditions effectively. With an internal resistance of up to 5.9Ω, it accurately mimics the output characteristics of devices like lead-acid batteries, thus delivering realistic testing results for various circuits and devices. The internal test sequence mode allows users to define voltage levels over specific time intervals and can be reused for performance evaluations across multiple voltage levels.
Another impressive feature is the analog input control, which can generate voltage profiles to simulate how a battery responds to variable load current demands, including large inrush currents. The capability to superimpose an AC signal on a DC output helps evaluate a circuit's response to electrical noise on its power source, broadening the testing flexibility.
Thanks to robust connectivity options, the Keithley 2260B power supplies integrate effortlessly into automated systems, featuring interfaces including USB, LAN, and an optional GPIB interface for streamlined control. Along with its fast discharge capability for quick voltage dissipation, the Keithley 2260B-80-27 also boasts a rapid 1ms transient recovery time, significantly reducing critical testing time in automated setups.
