Project Description

Overview

HT9816 High Current Programmable DC Electronic Load

The HT9816 programmable DC electronic load supports four mainstream operating modes: Constant Current (CC), Constant Voltage (CV), Constant Resistance (CR) and Constant Power (CP). It integrates abundant advanced test functions including automatic testing, dynamic load testing, over-current testing and timing sequence testing.

Equipped with a brand-new large touch screen matched with physical buttons and rotary knobs, this equipment eliminates the pain points of complicated parameter configuration and cumbersome operation of traditional loads. Operators can quickly configure complex test flows and parameters without frequent page switching, which greatly improves test efficiency. The intuitive graphical interface effectively prevents parameter setup errors.

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