The Tektronix PS-2521G is a triple-output GPIB programmable benchtop power supply engineered for automated test systems and laboratory applications requiring precise voltage and current control. Built for independent, series, and parallel operation modes, it delivers flexible power delivery across three isolated outputs with total combined capability of approximately 130 W. SCPI-compatible programming via GPIB interface enables seamless integration into test automation frameworks, while 100 onboard memory locations store and recall voltage and current settings for repeatable test sequences.
