Project Description
Overview
The HT9812-300W-150V-35A programmable DC electronic load supports four mainstream operation modes: Constant Current (CC), Constant Voltage (CV), Constant Resistance (CR) 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 touch screen, it solves the pain points of complicated parameter configuration and cumbersome operation of traditional electronic loads. The collaborative design of touch screen, physical buttons and adjustment knob allows users to quickly set complex test procedures and parameters 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 easy integration into various automated test systems. An external IO trigger port is also reserved for connecting external trigger signals.
