HT9817 High Current Programmable DC Electronic Load

Model HT9817 is a 2400W, 150V, 240A programmable DC electronic load. It integrates four standard operation modes: Constant Current (CC), Constant Voltage (CV), Constant Resistance (CR) and Constant Power (CP. It also supports advanced functions including auto-test, dynamic test, over-current test and sequence test.

Equipped with a new large touchscreen, combined with physical keys and an adjustment knob, the instrument eliminates complicated parameter setup and cumbersome operation. Operators can configure complex test procedures and parameters quickly without frequent interface switching, improving test efficiency while reducing configuration errors with an intuitive graphical interface.

Standard communication interfaces include RS232 and RS485, enabling seamless integration into automated test systems (ATE). An IO trigger port is also reserved for external signal triggering.
