Zhilian Shengda series converter
Price of medium-power online power supply This series of products adopts advanced D control technology and uses advanced high-power devices and is stable , a large-capacity sine wave online high-intelligence type designed based on advanced and efficient digital/analog hybrid technology 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. It is widely used in various industries and fields such as power, petrochemical, steel, pharmaceuticals, semiconductors, papermaking, transportation, automobiles, banks, securities, communications, insurance, education, and e-government.
Extraordinary protection with multiple functions is 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-voltage protection, under-voltage protection, output overload and short-circuit protection inverter. Multi-functional protection functions such as overheating protection 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 activate comprehensive protection functions simultaneously.
The ultra-wide input voltage and frequency range are compatible with diesel generators and can better adapt to harsh environments. Automatically identify and adapt/power system to meet the requirements of different power systems.
The standard battery cold start unit can start the power system directly from the battery, eliminating the need for customers to purchase a separate cold start unit to save customer investment costs.
Using 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.
The output isolation transformer is designed with super load capacity and 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 monitor each circuit online in real time throughout the process The state is sampled and detected to continuously output pure sine wave voltage to provide ultra-stable and high-quality power to the load.
The sixth generation inverter technology has the characteristics of smaller control power, lower saturation voltage drop and other characteristics to achieve high efficiency and high reliability operation. Higher system efficiency and excellent energy saving effect.
The high-precision patch manufacturing technology not only saves space, completely eliminates the pins in traditional circuits, but also completely eliminates the interference between chips caused by its own high-frequency signals, so that the chips can work normally without interference. It greatly improves the system's anti-interference performance and ensures high-reliability operation of the system.
The 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. The service life is extended and the battery is automatically charged and discharged 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 directly browse and set the battery charging method through the panel buttons and D display screen to conveniently and quickly realize intelligent management of the battery to ensure efficient and stable operation of the battery and extend its service life.
Humanized design, friendly human-machine interface and monitoring are easy to manage and maintain
The Chinese D 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 conveniently User operation and maintenance management.
Intuitive D working status indication allows administrators to grasp the current working status intuitively and quickly.
Modular panel design, front-end access process, beautiful appearance, convenient and fast maintenance.
The lower front air inlet and upper air outlet design are suitable for small spaces and can easily match the customer's cooling system. Flexible top or bottom cable entry and exit methods facilitate power system distribution.
The monitoring port and the included monitoring software can facilitate local or remote monitoring and management.
Powerful parallel function
Supports any number of unlimited parallel machines to facilitate low-cost system expansion for users. The minimum number required to represent the load represents redundancy. The greater the number, the higher the reliability of the system. The more reliable non-master-slave ring paralleling technology can still work reliably even if the parallel line fails unexpectedly.
Rich optional accessories provide more and more powerful system functions
Input isolation transformer: Provide isolation protection for users. Lightning protection cabinet: Significantly reduces the residual voltage of lightning strikes to ensure the safety of the equipment.
The dry contact card can extract the main abnormal information through the dry contact through the D dry contact interface. Users can easily use these signals to control some strong and weak current equipment to 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 that occur on each machine.
