Project Description

HT9811 DC Electronic Load 200W 150V 35A

Overview
The HT9811-200W-150V-35A programmable DC electronic load is equipped with four core operating modes: constant current (CC), constant resistance (CR), constant voltage (CV) and constant power (CP). It also integrates advanced functions including auto-test, dynamic test, over-current test and timing sequence test. Featuring a new large touchscreen combined with physical keys and an adjustment knob, the device eliminates the complexity of traditional parameter configuration and cumbersome operation. Operators can quickly set complex test flows and parameters without frequent interface switching, boosting overall test efficiency. The intuitive display interface effectively prevents setup errors. Standard RS232 and RS485 communication ports are built-in for seamless integration into various automated test equipment (ATE) systems. An external IO trigger interface is also reserved for external signal linkage.
