The ATS66321A series high-power programmable DC electronic load is a newly launched DC high-power electronic load by Shenzhen Antuosen Instrument Co., Ltd. The voltage range is divided into three types: 150V, 600V, and 1200V, and the power range is from 600W to 6kW. This series of electronic loads is mainly used for product testing in multiple fields such as new energy vehicle OBC, power batteries, charging piles, power electronics, servo/server power supplies, high-voltage UPS, military, photovoltaic, grid energy storage, aerospace, etc. Adopting a new generation digital controller, it has five basic modes and seven advanced modes built-in, and provides serialization function to meet users' programming, automation testing and other needs. The ATS66321A series electronic load has a wide range of voltage and current input, meeting various testing requirements for high current, low voltage, or high voltage, low current. Adopting a high power density design, the volume is half that of traditional electronic loads, and the weight is one-third.
