3. System Features
Intelligent products
The system adopts a decentralized control system, modular structure, simple screen assembly, and flexible configuration
Equipped with a communication port that can connect to a variety of external intelligent devices
Has a communication port With the self-detection function, communication port data can be viewed at any time to facilitate on-site problem finding.
The extended branch collection system can collect branch status anywhere, regardless of the screen position.
The control module adopts The large-screen LCD displays Chinese characters, and the parameters of each part of the system can be set through the monitoring module.
The module has the function of smoothly adjusting the output voltage and current, and has the function of battery charging temperature compensation.
It has telemetry, remote control, and remote control. The four remote functions of signal and remote adjustment realize unattended operation.
Automatic battery management and protection, real-time automatic monitoring of the battery’s terminal voltage, charging and discharging current, and intelligent control of the battery’s equalization charge. It is equipped with a battery Sound and light alarms for overvoltage, undervoltage and charging overcurrent.
The machine insulation monitoring can run multiple machines in parallel, and the highly reliable communication interface forms a grounding line selection network to avoid system paralysis caused by host failure when one host is running.< br/> Reliability design
Adopt modular design of switching power supply, + hot backup.
The charging module can be hot-swapped when powered, which greatly reduces the average maintenance time.
All key components of the system are adopted High-quality imported brand-name products.
The power bus and control bus can be selected according to different plans. They can be directly powered by the charging module alone, and can be hot-backed up through the voltage reduction device.
Hardware low-difference independent current sharing technology, module The maximum unbalance of the output current between the two channels is less than.
Reliable three-level lightning protection system and electrical insulation measures ensure safer operation of the system.
Advanced AC switching function, priority selection of one channel, delay between the two channels Switching ensures that the switching process is safe and reliable.
The system design adopts other international standards to effectively prevent on-site monitoring system failures.
