Project Description

Overview

HT9818B High-Voltage High-Power Programmable DC Electronic Load

The HT9818B is a 3000W, 500V, 120A programmable DC electronic load. It is equipped with four mainstream operating modes: Constant Current (CC), Constant Voltage (CV), Constant Resistance (CR) and Constant Power (CP). It also integrates abundant advanced test functions including auto-test, dynamic test, over-current test and timing sequence test.

Featuring a brand-new large touchscreen matched with physical buttons and an adjustment knob, it eliminates the drawbacks of complicated parameter setup and cumbersome operation of traditional loads. Operators can rapidly configure complex test flows and parameters without frequent page switching, greatly improving test efficiency. The intuitive graphical interface effectively prevents configuration errors.

Standard RS232 and RS485 communication interfaces are pre-installed for seamless integration into various automated test systems (ATE). An IO trigger port is reserved for external trigger signal connection.
