Project Description

Overview

HT9814 1200W 150V 240A Programmable DC Electronic Load

The HT9814 programmable DC electronic load is equipped with four standard operating modes: Constant Current (CC), Constant Voltage (CV), Constant Resistance (CR) and Constant Power (CP. It also integrates abundant advanced functions including auto-test, dynamic load test, over-current test and sequence timing test.

Adopting a new large touch screen paired with physical buttons and knobs, the equipment solves the pain points of complex parameter configuration and cumbersome operation on traditional loads. Users can quickly set up complex test flows and parameters without frequent page switching, greatly improving test efficiency. The intuitive graphical interface effectively avoids configuration errors.

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