24V/48V/110V/220V 50A Intelligent Battery Discharge Indicator DC Load Bank

I.General Introduction

Battery Load Bank is a special instrument for the test of NiCD and Lead-acid storage battery string of the whole string voltage of 24V, 48V, 110V, 220V, in communication room, and cell voltage of 1.2V/2V/6V/12V, and it adopts current advanced testing technology theory, and has obtained a series of breakthrough in research and application of new technology, new parts, new material and new techniques, which is designed in accordance with the requests of national related testing and maintenance regulations and it is a special detection instrument for the performance detection of stationary battery. Its big discharge power, small volume, light weight, complete function of data management software of upper computer could greatly reduce the work load of daily testing and maintenance of stationary battery.

II.Main Functions And Features

l The product is utilized color touch screen. It can be operated via finger or the touch pen with convenience and flexibility.

l Data save mode: Internal save and external save(SD Card )

l Enhanced over voltage protecting function ,

l Automatically recovery the over current protecting function

l Overheating protection .

On line Monitoring Function:

l When the battery string is under the conditions of on-line discharge, uniform charge, and floating charge, the instrument could perform real-time monitoring for the battery string and cell; the monitoring includes the whole string voltage, cell voltage, the whole string charge/discharge current, the whole string charge capacity, the whole string discharge capacity, monitoring time and etc

Discharge Function:

Perform discharge of constant current taking advantage of intellectualized dummy load after the battery string is removed from system, set up the parameters of "discharge current","discharge time ","discharge capacity" ,"final protective voltage of whole string" and "final protective voltage of cell", and the tester could carry out discharge function automatically, display discharge current,battery discharged capacity,the whole string voltage, cell voltage, discharge time and etc at real time; when the string reaches setup value of final discharge voltage,setup value of final discharge capacity,setup value of final discharge time,any cell voltage is below setup value of final cell voltage or manual final operation could stop discharge test. The final cell voltage conditions can also be set to alarmed is not only stop .

l It could save 10 groups of on-line monitoring data and 10 groups of discharge test data; the user could perform query, deletion, and export operation of SD card.

l  The computer could connect with instrument via the serial, perform test control and real-time monitor of instrument, and carry out  graphic analysis.

l The computer could connect with instrument via the serial, perform test control and real-time monitor of instrument, and carry out graphic analysis.

Automatic protection function:

l The tester would stop the test automatically when it could detect the abnormity of the whole battery string or cell, and the working abnormity of tester in order to make protection of battery during the test process.

l The host machine of tester adopts the design integrating the monitoring part with power part, the power part adopts new-type high-effective parts, and it is a storage battery comprehensive tester with small volume and high efficiency.

l Humanized operation interface, simple operation, clear flow, and each operation could have English cue. Aquamarine blue high-brightness, large-screen LCD, and the display effect are clear and beautiful.

l Powerful functions of upper computer data management software, friendly interface, which could offer data management, print, analysis, statistics of report forms, automatic creation of test report , etc

III.Test Procedure Introduction:

On Line Monitoring Test Procedure

First Step: Connect Cell Voltage monitoring module (See details in section 2.4)

Second Step:  Connect group voltage test line to the two poles of battery string (see the details in section 2.5)

Third Step: Plug in and Switch on the tester .

Forth Step: Enter into on line monitoring setup . (see the details in section 3.1 )

Firth Step: Press " OK " Start test .

Discharge Test Procedure:

Step1: Connect cell voltage monitoring module ( See details in section 2.4)

Step2: Pull" On" on the discharge switch ( to prevent reverse connection of the discharge cable and damage the tester , and also if misconnection, the warning will be given.)

Step3: Connect the discharge cable to the the host machine and battery bank respectively. ) Note: Red line is + positive ; Black line : - Negative ) reverse connection will be warning . ( See details in section 2.5 )

Step 4: Connect group voltage test line to the two poles of battery string.

Step 5: Plug in and switch on the tester.

Step 6 : Enter into discharge test parameters setup.( see details in 3.2)

Step 7: Pull " off"on the discharge switch .

Step 8: Press " ok" start test
