NDDCF Battery Charge and Discharge Tester

Product Introduction

       Battery Discharge Tester is specifically designed for verifying discharge tests, capacity testing, daily maintenance of battery packs, engineering acceptance, and other DC power load capacity tests.

       Battery Discharge Tester uses new PTC ceramic resistors as the discharge load in the power consumption part, completely avoiding red-hot phenomena, ensuring safety, reliability, and pollution-free operation. The entire unit is controlled by a microprocessor, with LCD display and Chinese menu. The外观 design is novel, compact, lightweight, and easy to move. After setting various discharge parameters, it automatically completes the entire constant current discharge process, achieving full intelligence and making the discharge process safer. It is particularly suitable for battery acceptance, verification discharge tests, and regular deep discharge applications.
       The portable and intelligent professional design of the Battery Discharge Tester series makes discharge testing simple and effortless, greatly reducing the labor intensity of professional maintenance personnel and enhancing the scientific and intelligent nature of discharge testing.
       Features constant current discharge function for battery packs: The constant current discharge current is continuously adjustable, allowing precise measurement of battery pack capacity.
       Equipped with multiple alarm提示 functions: Test current exceeding or falling below set values, voltage above or below set values, reverse polarity, excessive temperature, short circuit overcurrent, fan failure, etc. The instrument can automatically alarm and stop discharging.
       Allows pausing and parameter modification during discharge: Users can manually pause discharge, modify discharge settings (lower limit voltage, discharge current, discharge time, etc.) during the process without needing to terminate the test, unlike traditional discharge instruments that require restarting after termination.
       Supports remote control discharge: The PC software can connect to the discharge tester via RS485 communication cable for PC-controlled discharge.

Product Features

☆、7-inch color touch LCD display, supports dual language (Chinese and English), suitable for domestic and international customers.
