HT9818 High Current Programmable DC Electronic Load

The HT9818 is a 3000W, 150V, 240A programmable DC electronic load. It comes with four standard 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 touchscreen paired with physical buttons and an adjustment knob, it solves the pain points of complex parameter configuration and cumbersome operation of traditional loads. Users can rapidly set up complex test procedures and parameters without frequent interface switching to boost work efficiency. The intuitive graphical interface effectively prevents parameter setup errors.

Standard RS232 and RS485 communication interfaces are pre-installed for seamless integration into various automated test systems. An IO trigger port is also reserved for connecting external trigger signals.
