HT9813 Programmable DC Electronic Load 600W 150V 120A

This HT9813 programmable DC electronic load supports four standard operation modes: constant current (CC), constant resistance (CR), constant voltage (CV), constant power (CP). It is further equipped with abundant advanced functions including auto-test, dynamic load test, over-current test and timing sequence test. The unit adopts a new large touchscreen paired with physical keys and knobs, eliminating the complicated parameter configuration and cumbersome operation of traditional loads. Operators can quickly set complex test flows and parameters without frequent page switching to boost testing efficiency, while the intuitive interface minimizes configuration errors. Standard interfaces include RS232 and RS485 for seamless integration into automated test systems, plus an IO port for external trigger connection.
