3、 Intelligent battery management
1. Automatic regulation of battery discharge termination protection voltage
According to the technical standards provided by battery manufacturers, the setting of battery discharge end voltage protection point is different from discharge current. Emerson itrusttm series UPS products can automatically judge the discharge rate of the battery by detecting the discharge current of the battery, and then automatically adjust the battery discharge, terminate the voltage, and prolong the service life of the battery.
2. Automatic conversion of equalizing and floating charge
Itrusttm series UPS adopts the advanced technology of average floating charge conversion. According to the detection of battery charging current and the judgment of battery capacity, it can automatically carry out average floating charge conversion, greatly saving charging time, activating battery and prolonging battery service life.
3. Automatic temperature compensation
Itrusttm series UPS can automatically adjust the floating charge voltage according to the change of ambient temperature to ensure the effective capacity of battery and prolong the service life of battery.
4. Parallel charger with automatic current sharing
Itrusttm series UPS has specially designed a parallel charger with automatic current sharing, and adopts mature communication power parallel technology. The current sharing imbalance is less than 3%, which can meet the user's desire for battery energy storage as soon as possible.
4、 Pure online function
Itrusttm series UPS adopts on-line double conversion structure, which has the advantages of not being disturbed by power grid fluctuation. Moreover, when the mains power is cut off or recovered, the UPS has no output switching time, which can solve a series of problems such as frequency fluctuation, voltage fluctuation, power supply interference, lightning stroke, etc., and can provide comprehensive and thorough protection for user equipment.
V. powerful battery protection function
When the user accidentally connects the battery reversely or the battery connection is poor, the user will give an alarm and refuse the operation of the battery. Real time monitoring of battery charging and discharging, over-current and current limiting protection can prevent users from battery sexual damage caused by battery over discharge and shorten battery life due to overcharge. The early warning function of battery undervoltage timely informs the user for relevant treatment, so as to avoid large loss. DSP can detect the faulty battery in time by setting the periodic battery self-test function to avoid the harm caused by system failure.
6、 Intelligent fan speed regulation
In order to suppress the noise coefficient of the installation site, the microprocessor can automatically adjust the speed of the fan according to the internal temperature and output power, so as to reduce the noise, prolong the service life of the fan and save energy.
7. Flexible and convenient battery connection design
The drawer type battery box and bypass switch for maintenance are designed for series 6KVA and 10kvaups. The battery pack can be easily repaired and replaced under the condition that the user's equipment is powered on continuously. The replacement time is less than 1 minute.
8. Intelligent modular charger
The high-performance charger with the functions of input overvoltage and undervoltage protection, output overvoltage and undervoltage protection, over temperature protection, battery reverse connection protection, output short-circuit protection and independent current sharing function is adopted. Different users can freely combine and connect in parallel to increase the charging current to meet the user's demand for rapid energy supply.
PFC technology is adopted in this series of chargers, so that the input power factor of the charger is greater than 0.99, and the battery is charged by constant voltage and constant current with very small ripple current (≤ 20mA), which greatly protects the user's battery and prolongs the service life of the battery.
9. High power IGBT devices
Itrusttm series UPS adopts IGBT power devices with low voltage and high working current. It has the advantages of convenient drive control, high efficiency, stable performance, strong current impact resistance, and is suitable for loads with high surge impact, such as computers. This module is the fourth generation IGBT module with excellent performance, stability and reliability, which greatly ensures the reliability and stability of the system operation.
10、 Comprehensive protection function
Itrusttm series UPS integrates input over-voltage and under-voltage protection, rectifier over-voltage and under-voltage protection, output over-voltage and under-voltage protection, output short-circuit protection, output current limiting protection and over-temperature protection, which greatly ensures the reliability of the system.
