HT9818D High Current Programmable DC Electronic Load

The HT9818D is a 3000W, 500V, 240A programmable DC electronic load. It supports four mainstream operating modes: Constant Current (CC), Constant Voltage (CV), Constant Resistance (CR) and Constant Power (CP). It is integrated with abundant advanced test functions including auto-test, dynamic test, over-current test and timing sequence test.

Equipped with a brand-new large touchscreen matched with physical buttons and an adjustment knob, it solves the pain points of complicated parameter configuration and cumbersome operation of traditional electronic loads. Users can rapidly set up complex test flows and parameters without frequent interface switching, greatly boosting test efficiency. The intuitive graphical interface effectively avoids parameter configuration errors.

Standard RS232 and RS485 communication interfaces are pre-installed for seamless integration into various automated test systems (ATE). An IO trigger port is reserved for connection with external trigger signals.
