View full details

The Keithley Series 2260B Programmable DC Power Supplies are a family of benchtop and rack-compatible DC sources spanning twelve models at 360 W, 720 W, and 1080 W output levels. Voltage options cover 30 V, 80 V, 250 V, and 800 V, with current capabilities ranging from 1.44 A to 108 A depending on model. This combination of output ranges and multiple control interfaces makes the Series 2260B suitable for use across research and design, quality control, and production test environments.

Per the manufacturer, the Series 2260B is designed for environmental test, stress test, and accelerated life testing; LED and high-power component testing; automotive testing; battery research and test; and production test. Programmable voltage or current rise and fall times allow controlled power delivery to prevent overshoot spikes and excessive inrush current, eliminating damage to components, modules, or devices and generating more precise characteristic I-V curves for components such as LEDs.

Brand Heritage

Keithley Instruments was acquired by Danaher Corporation in 2010 and joined the Tektronix family of measurement brands under Danaher's test and measurement portfolio. In 2016 the test and measurement businesses, including both Keithley and Tektronix, were spun off as part of Fortive Corporation. Keithley-branded products such as the Series 2260B continue to ship under the Keithley name as A Tektronix Company.

Compare Other Models in This Series

The Series 2260B is structured as a 4-by-3 matrix: four voltage tiers (30 V, 80 V, 250 V, 800 V) crossed with three power tiers (360 W, 720 W, 1080 W), producing twelve distinct models. Within each voltage tier, stepping up in power increases the available output current proportionally while maintaining the same voltage envelope, slew rate range, and protection feature set.

Voltage tier selection drives the application class: the 30 V and 80 V models target general electronics, automotive low-voltage rails, and LED test work, while the 250 V and 800 V models address higher-voltage component characterization, battery emulation across larger packs, and applications requiring the extended internal resistance range up to 555 ohms.

Each new Series 2260B model below is listed on its own dedicated product page with condition-matched pricing and availability. Specifications, accessories, and interface options follow the same datasheet structure across the family; selection is driven by the voltage and current envelope required for the device under test.

The 2260B-30-36 is the entry point of the Series 2260B family at 360 W: 0 to 30 V output with 0 to 36 A current capability. It shares the same 1 ms load transient recovery, 60 mV peak-to-peak CV ripple, and 0.1% plus 10 mV programming accuracy as the higher-power 30 V variants, while occupying the narrowest 71 mm chassis width in the family.

Across the family, the most significant differences are output voltage range, output current range, ripple and noise specifications, and slew rate ranges. The 360 W models occupy a 71 mm wide chassis, the 720 W models a 142 mm chassis, and the 1080 W models a 214 mm chassis, all at the same 124 mm height and 350 mm depth. Maximum power consumption scales from 500 VA on 360 W units to 1500 VA on 1080 W units.

The comparison table that follows lists each Series 2260B model with its rated voltage, rated current, output power, ripple specifications, programming accuracy, and slew rate ranges so the differences between tiers can be evaluated against the device under test requirements.

Model Output Voltage Output Current Output Power
2260B-250-4 0–250 V 0–4.5 A 360 W
2260B-30-36 0–30 V 0–36 A 360 W
2260B-30-72 0–30 V 0–72 A 720 W
2260B-30-108 0–30 V 0–108 A 1080 W
