Project Description

OVERVIEW
The HT9812C-300W-150V-60A programmable DC electronic load supports four standard operation modes: Constant Current (CC), Constant Voltage (CV), Constant Resistance (CR) and Constant Power (CP). It is equipped with abundant advanced test functions including auto-test, dynamic test, over-current test and timing sequence test. Featuring a brand-new large touch screen matched with physical buttons and adjustment knob, the instrument eliminates the complicated parameter setting and cumbersome operation pain points of traditional loads. Users can quickly configure complex test procedures and parameters without frequent page switching, which greatly improves test efficiency. The intuitive display interface effectively avoids parameter configuration errors. Standard RS232 and RS485 communication interfaces are pre-installed for seamless integration into various automated test systems. An external IO trigger port is reserved for connecting external trigger signals.
