Project Description

Overview

HT9906EL -6000W Programmable DC Electronic Load

The HT9906EL programmable DC electronic load supports four standard operating modes: constant current (CC), constant resistance (CR), constant voltage (CV), and constant power (CP). It is also equipped with abundant advanced functions including automatic test, dynamic test, over-current test, and timing test. Featuring a brand-new large touch screen, it eliminates the complexity and cumbersome operation of traditional parameter configuration. The combined touch screen, physical buttons and rotary knob enable fast setup of complex test procedures and parameters, reducing frequent interface switching and improving testing efficiency. The intuitive interface effectively prevents configuration errors.

Standard interfaces include RS232 and RS485 communication ports for seamless integration into various test systems, plus an IO port for external trigger connection.

Features

  • Four operating modes: CC, CV, CR, CP
  • Automatic test and list test functions
  • Dynamic mode up to 50kHz
  • Measurement resolution: 0.1mV (voltage), 0.1mA (current)
  • Built-in battery test function
  • OCP test and remote sensing measurement
  • Short-circuit simulation function
  • Dedicated CR-LED test mode
  • Voltage & current ripple measurement function
  • Power-off parameter memory retention
  • Storage capacity for 100 groups of test parameters
  • Standard RS232 / RS485 communication interfaces
