HT9811B Programmable DC Electronic Load 200W-500V-18A

The HT9811B programmable DC electronic load supports four standard operating modes: Constant Current (CC), Constant Resistance (CR), Constant Voltage (CV) and Constant Power (CP). It is also equipped with abundant advanced test functions including auto-test, dynamic test, over-current test and timing sequence test. Equipped with a brand-new large touchscreen, the instrument solves the pain points of complicated parameter setup and cumbersome operation of traditional loads. The collaborative design of touch screen, physical buttons and adjustment knob allows users to configure complex test procedures and parameters rapidly without frequent page switching, greatly improving test efficiency. The intuitive display interface effectively avoids parameter setting errors. Standard RS232 and RS485 communication interfaces are pre-installed for seamless integration into various automated test systems. An external IO trigger port is also reserved for connecting external trigger signals.
