Project Description

Overview

HT9815B High Voltage Programmable DC Electronic Load

The HT9815B programmable DC electronic load supports four mainstream operating modes: Constant Current (CC), Constant Voltage (CV), Constant Resistance (CR) and Constant Power (CP). It is equipped with comprehensive 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, solving the pain points of complicated parameter setup and cumbersome operation of traditional electronic loads. Users can rapidly configure complex test procedures and parameters without frequent page switching, which greatly improves test efficiency. The intuitive graphical interface effectively prevents parameter configuration errors.

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