Project Description

Overview

8817B DC Electronic Load (2)

HT8XX-M load is a precision programmable DC electronic load controlled by a high performance microprocessor. It uses 3.5-inch TFT true color LCD display with Chinese and English menu.

Offers 4 basic working modes (CC/CV/CR/CW) and 10 functional modes.

With comprehensive protection, over-heat protection, over-current protection, over-power
protection, over-voltage protection, loop oscillation protection. HT8XX-M series E-load supports RS232,
LAN, USB and analog interfaces to fit your versatile solution and testing needs.

Test Function
