Battery online monitoring system – Model 3920

3920 battery online monitoring system perform a full range of monitoring for DC screen backup power supply for a full range of monitoring, including internal resistance test, pole temperature test, single-voltage monitoring, group-end charging and discharging voltage, current monitoring and intelligent analysis and management. The battery safety hazards can be found during operation in time. The long-term monitoring of batteries can be an effective way to prolong the life of the battery to ensure that the deterioration of batteries for the early detection. Meanwhile, the system can track the performance balance of battery, when the faulty batteries in a serious deterioration performance be found, the system will immediately alarm and can be the basis for the battery pack “fine” maintenance. The the batteries can be replaced before running out of power, which can reduce the risk of battery failure and save money.

Features

System fault tolerance The system does not have any interference to the UPS charging system and working circuit. The voltage acquisition line is not directly connected to the monitored battery, and the middle is connected by ohmic resistor, which eliminates the dangers of self-discharge of the battery, sparks on the scene, electrocution of the personnel, and injury of the battery brought by the short circuit of the measurement cable itself or the failure of the module.

The detection channels of the acquisition unit adopt high impedance input mode, and the current of the detection circuit is less than microampere level, which has no adverse effect on the battery.

The system can work independently of the monitored equipment, low power consumption, low requirements for the power supply system, does not affect the user’s normal power supply line

Anti-over voltage, over current and high-frequency magnetic field interference

The system is required to have a wide operating voltage range, strong prevention capability for over current and voltage , and design with anti-surge circuits to normal operation under high-frequency and strong magnetic field working environments.

Online maintenance The system adopts modular design, good independence between modules, strong online maintainability. Online maintenance does not affect the normal work of the monitored equipment.
Flame retardancy The system use components with good flame-retardant characteristics so that malfunctions caused by short-circuits and over currents in the system itself will not cause open flame burning.
Explosion-proof The system use relays in good performance, no channel switching sparks, and no contact connecting devices that generate open flames.
Display intuition 7-inch touch screen and monitoring host integrated design, easy to install, real-time data view, can also be read through the background.
Intelligent operation The module adopts automatic numbering, the data can be exported locally and in the background, and intelligent integrated maintenance.
Strong anti-interference The internal resistance test adopts the Kelvin four-terminal AC injection method, the test frequency is dynamically adjusted according to the UPS parameters, and the high anti-interference internal resistance value is not interfered by the UPS ripple.
Line separation design Adopt 6-core acquisition line, voltage, internal resistance and temperature are independent channels without interfering with each other, which improves the stability of testing.
Self-calibration function The instrument is equipped with internal resistance calibration and correction function, which can calibrate and correct the measured value to ensure the measurement accuracy.

Specifications may vary by configuration; final technical data is confirmed in the quotation.
