HT9812B Programmable DC Electronic Load 300W-500V-18A

The HT9812B programmable DC electronic load comes with four mainstream operating modes: Constant Current (CC), Constant Voltage (CV), Constant Resistance (CR) and Constant Power (CP). It also integrates 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 troubles of complex parameter configuration and cumbersome operation of traditional electronic loads. Combined with physical buttons and an adjustment knob, the new touch panel enables quick setup of complicated test flows and parameters without frequent interface switching, greatly boosting test efficiency. The intuitive display screen effectively prevents parameter setup 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 external signal connection.
