General Information:
ET54A+ programmable DC electronic load provides 1mV/ 1mA high resolution and
precision with superior performance, which can be widely used in charger, switching power supply, linear power supply, battery and other production line testing, as well as the research institutions and other research and development fields.
Products Features:
Ø User-friendly Design:
l It adopts 2.8-inch TFT LCD screen with rich display contents; Support Chinese and English;
l The operation process is simple and convenient, and with visual interface display system, it is
easy to get started.
l Key lock function to prevent misoperation;
Ø High Performance Load
l It provides CC, CV, CR, CP and CC+CV, CR+CV several basic measurement modes;
l It provides professional battery test and LED test;
l The Tran test mode can test the dynamic output performance of the power supply;
l The scan test mode can test the continuity of power output within a certain range;
l The list test mode can simulate a variety of loading status changes;
l The short circuit test can be used to simulate load short circuit;
l Support external trigger input (DB9 interface is required);
l Built-in buzzer alarm;
l Maintain data storage in case of power failure;
l Remote operation via USB, RS-232 (optional) or 485 (optional) interfaces;
l Equipped with software remote compensation
Ø Multiple safety protection:
l It provides overcurrent, overvoltage, overpower, over temperature protection. The overvoltage
and overcurrent parameters can be set flexibly, so as to effectively protect the load;
l It has intelligent fan speed control function, which can effectively reduce the fan noise when it is working.
l With input polarity reverse prompt;
