MS-3985 220V  40A 100ALoad group of battery charge and discharge tester 

This product integrates constant current discharge, intelligent charging, single-cell monitoring, and activation functions. Its multi-functional design reduces enterprise costs and lowers the labor intensity of maintenance personnel, providing comprehensive and scientific testing methods for battery and UPS power supply maintenance. It is used in telecommunications, base stations, power utilities, and other sectors. It performs deep discharge and subsequent charging as needed, ensuring the battery pack remains in optimal condition and extending battery life, making it the best assistant for battery maintenance.

1. DC220V voltage charging and discharging function: A single unit can meet the charging and discharging test requirements of DC220V battery packs.
2. Constant current discharge function for battery packs: The constant current discharge current is continuously adjustable, accurately measuring the battery pack capacity.
3. Intelligent charging function for battery packs: Intelligent three-stage charging, with continuously adjustable charging current, meeting the charging and maintenance needs of battery packs.
4. Activation function: The number of charge-discharge cycles can be set to activate the battery pack, effectively improving the capacity of individual cells.
5. Online monitoring and capacity analysis function: Real-time online monitoring and display of all test data: current, battery pack voltage, single-cell voltage, discharge time, and capacity; at the end of the verification discharge test, it can quickly analyze the remaining capacity of each cell.
6. Single-cell voltage detection function: Using a wireless single-cell monitoring module, compatible with 1-16V single-cell voltage monitoring, each wireless monitoring module can monitor 12 cells simultaneously.
7. Real-time single-cell voltage detection function: The current voltage of each battery cell is automatically displayed in real-time on the host screen, and the six cells with the lowest voltage are automatically displayed in real-time.
8. Multiple alarm functions: Alarms for current exceeding or falling below the set value, voltage exceeding or falling below the set value, reverse polarity, over-temperature, short circuit overcurrent, fan failure, etc. The instrument will automatically alarm and stop discharging.
9. Pause and parameter modification function during discharge: During the discharge process, the discharge can be manually paused, and discharge setting parameters (lower limit voltage, discharge current, discharge time, etc.) can be modified without terminating the test. This is different from traditional discharge instruments that require terminating the discharge and restarting the discharge test. 10. Remote control discharge function: After connecting the PC-based upper computer software and the charge-discharge tester via an RS485 communication cable, PC-based control of discharge is possible.
