The Keithley 2280S-60-3 is a precision bench power supply designed for demanding test and measurement applications requiring stable, low-noise power delivery. It provides accurate voltage and current control across 0–60 V and 0–3 A, supporting up to 180 W output. The instrument delivers programmable accuracy of ±(0.05% of setting + 0.05% of range) for voltage and ±(0.1% of setting + 0.1% of range) for current, with readback accuracy of ±(0.05% of reading + 0.02% of range) and ±(0.1% of reading + 0.05% of range) respectively.
