The Keysight SL1047A Scienlab Charging Discovery System is a second-generation high-power platform for testing electric vehicle (EV) and EV supply equipment (EVSE) charging interfaces across global standards. It delivers scalable DC power up to 900 kW (expandable to 1,200 kW) with configurable voltage from 1,000 V DC to 1,500 V DC and current capability from 400 A DC upgradeable to 600 A or 800 A DC. The system supports AC testing at up to 100 A AC, with measurement accuracy of ±150 mV for voltage and ±100 mA for current. Built on a modular architecture, the SL1047A enables conformance, interoperability, and advanced communication testing in R&D and end-of-line applications.
