Overview

HT9815 High Current Programmable DC Electronic Load

The HT9815 programmable DC electronic load supports four standard operation modes: Constant Current (CC), Constant Voltage (CV), Constant Resistance (CR) and Constant Power (CP). It is equipped with abundant advanced test functions including automatic testing, dynamic load testing, over-current testing and timing sequence testing.

This instrument adopts a brand-new large touch screen combined with physical buttons and rotary knobs, which solves the pain points of complex parameter configuration and cumbersome operation of traditional electronic loads. Users can quickly set up complex test procedures and parameters without frequent page switching, greatly improving test efficiency. The intuitive graphical interface effectively prevents parameter setting errors.

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