The Keysight E36312A is an 80 W triple-output programmable DC power supply engineered for benchtop and automated test environments. Each of its three independent, electrically isolated outputs delivers independently programmable voltage and current with exceptional regulation, enabling simultaneous powering of multiple circuits or devices. The unit combines precise measurement capability—functioning as an integrated voltmeter and ammeter—with advanced sequencing and data-logging functionality for comprehensive test automation and validation.
