HT9812D Programmable DC Electronic Load 300W 500V 35A

The HT9812D programmable DC electronic load features four standard operating modes: constant current (CC), constant resistance (CR), constant voltage (CV) and constant power (CP). It is further equipped with abundant advanced functions including auto-test, dynamic load test, over-current test and sequence timing test.

Adopting a new large touchscreen combined with physical keys and an adjustment knob, the device eliminates the complicated parameter setup and cumbersome operation of older models. Users can quickly configure complex test workflows and parameters without frequent interface switching, greatly improving testing efficiency, while the intuitive display reduces setup errors.

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