Technical Features
Zhilian Shengda series high-end three-phase industrial frequency online power supply with 3 turns. This series of products adopts advanced control technology and uses advanced high-power devices B and On the basis of stable, advanced and efficient digital/analog hybrid technology, a large-capacity sine wave online high-intelligence model is designed that integrates digitalization, informatization and networking. Provide reliable power protection for today's centralized server rooms, network management centers, computer centers, and various advanced industrial automation equipment. Widely used in various industries and fields such as electric power, petrochemicals, steel, pharmaceuticals, semiconductors, papermaking, transportation, automobiles, banks, securities, communications, insurance, education, e-government, etc.
Extraordinary protection, multiple functions, durable, stable and worry-free
Double protection of software and hardware. Even if the software protection fails, the hardware protection system can still work normally. It has AC input over and under voltage protection, output overload, Short circuit protection, inverter overheating protection and other multi-functional protection functions and fault warning functions greatly ensure the stability of system operation. The high-speed digital microprocessor detects the working status of all devices and circuits online in real time. When a fault occurs, the system will promptly and accurately send out a variety of audible and optical alarm messages, and simultaneously activate the comprehensive protection function.
Ultra-wide input voltage and frequency range, compatible with diesel generators, and more adaptable to harsh environments. Automatically identify and adapt to the power supply system to meet the requirements of different power systems.
The standard battery cold start unit can directly start the power system from the battery without the need for customers to purchase a separate cold start unit, saving customer investment costs.
Adopting three-phase independent modulation and full-bridge inverter technology, it can provide normal and reliable power supply even when the three-phase load is unbalanced.
Output isolation transformer design, super load capacity, can easily cope with various impact loads.
Fully digital control, advanced inverter technology, cutting-edge manufacturing, high performance, high reliability, high energy saving
Fully digital technology can control circuit operation, parameter setting and system management at high speed and reliably, and provide real-time online control throughout the process Each circuit status is sampled and detected, and a pure sine wave voltage is continuously output to provide ultra-stable, high-quality power to the load.
The sixth generation B inverter technology has the characteristics of smaller control power and lower saturation voltage drop, achieving high efficiency and high reliability operation. Higher system efficiency and excellent energy saving effect.
The high-precision chip manufacturing technology not only saves space, completely eliminates the pins in the traditional circuit, but also completely eliminates the interference between chips caused by its own high-frequency signal, so that the chip can be free from interference. The normal operation of the system greatly improves the anti-interference performance of the system and ensures the high reliability of the system operation.
Intelligent and humanized battery management system ensures stable operation and long life of the battery
The intelligent battery management system adopts advanced intelligent charging control method to select the optimal charging method according to the battery type and battery usage status. , so that the service life of the battery can be extended, and the battery can be charged and discharged automatically and regularly. Functions such as overcharge and over-discharge protection protect the battery and send out audible and visual alarms to the administrator in time and initiate protection in a timely manner.
Users can browse and set battery charging methods directly through the panel buttons and display screen, conveniently and quickly realizing intelligent management of the battery, ensuring efficient and stable operation of the battery and extending its service life.
Humanized design, friendly human-machine interface and monitoring, easy management and maintenance
The Chinese LCD interface can display the load, battery capacity, input and output parameters and fault information, and the maximum number of fault alarm information can be recorded , to facilitate user operation and maintenance management.
Intuitive working status indication allows administrators to intuitively and quickly grasp the current working status.
Modular panel design, front-end access, beautiful craftsmanship, and convenient and quick maintenance.
The lower front air inlet and upper air outlet design are suitable for small spaces and can more conveniently match the customer's cooling system. Flexible top or bottom cable entry and exit methods facilitate power system distribution.
The R monitoring port, combined with the included monitoring software, can facilitate local or remote monitoring and management.
Powerful parallel function
Supports any number of unlimited parallel machines, making it convenient for users to expand the system at low cost. It represents the minimum number required by the load and represents the redundancy number. The larger the number, the higher the reliability of the system. The more reliable non-master-slave ring paralleling technology allows the paralleling system to work reliably even if the paralleling line fails unexpectedly.
Rich optional accessories, providing more and more powerful system functions
Input isolation transformer: Provides isolation protection for users. Lightning protection cabinet: Significantly reduces the residual voltage of lightning strikes and ensures the safety of the equipment.
The dry contact card can lead out the main abnormal information through the dry contact through the B dry contact interface. Users can easily use these signals to control some strong and weak current equipment and facilitate access to the environmental power monitoring system.
Network card/centralized monitoring card: The card can be connected to the Ethernet to achieve remote monitoring. The centralized monitoring card can monitor multiple machines at the same time and record events and alarms on each machine.
