The modular UPS is composed of a rack, a UPS power module, a static switch module, a display communication module, and a battery pack.
It adopts drawer type, high intelligence multi-module modular design, online hot plug technology, online replacement and online maintenance, which reduces maintenance difficulty and implements zero downtime work. With N+X parallel redundant wireless technology, each module rack can be completely separated, which is convenient for users to expand or reduce capacity in the future, and is very convenient to use. In the inverter structure, the concept of "multi-level inverter" is preferentially applied, so that the loss of the power device is greatly reduced, and the output voltage is reduced by nearly double the high-order harmonic, thereby reducing the volume and increasing the power density.
The product is the first in the UPS industry to use a 32-bit digital signal processor as the core processing chip. This chip is the most advanced and powerful 32-bit DSP processor on the international market. With a running speed of up to 150MPS, it has powerful numerical computing capabilities and rich event management capabilities. It is especially suitable for handling control systems with complex, high precision, high speed and real-time requirements. Its adoption makes this product the greatest improvement in terms of electrical performance, reliability and function.
concept1. Power module: including the rectification, charging, inverter and related control circuits of the traditional UPS.
2. Static switch module: The shared power supply channel when the UPS is overloaded is composed of two-way thyristor and control circuit.
3. Display communication module: as a platform for human-machine dialogue and network monitoring.
1, with a variety of work standards
The product is available in a variety of formats and is easy to operate. It can be used in a variety of ways: 1/1, 1/3, 3/1 or 3/3, input frequency can be 50Hz or output frequency 60Hz, output The voltage can be set to 220V, 230V, 240V. If the input and output transformers are configured, the power supply requirements of all countries and regions in the world can be met.
2, small size, high power density
The product has high working efficiency and high power density, which is its biggest feature. One power module size is: (H&TImes; W&TImes; D) mm: 133 & TImes; 482 & TImes; 46 5KVA (4000W), 10KVA (8000W), 15KVA (12KW) and 20KVA (16KW) power output.
3. Environmental protection
UPS total harmonic distortion (THDI) 3%, the total harmonic distortion of the output under linear load is less than 2%, the harmonic interference to the power grid is minimized, and the grid load and power loss are effectively reduced. Excellent input parameters, showing pure resistance characteristics to the mains grid, is an ideal environmentally friendly and efficient UPS.
4, energy efficient
Energy saving and consumption reduction, the country advocates environmental protection and energy saving today, the green energy-saving modular UPS has attracted much attention, and the input power factor is above 0.999. Reduced line losses and increased power utilization. The inverter efficiency can reach more than 98%, which improves the working efficiency of the whole machine, reduces the loss and saves the electric energy.
5, scalability, easy to install, maintain, replace, upgrade
The model consists of various modules, which can realize the hot plugging function, and each module rack can be completely separated, which is convenient for users to expand or reduce capacity in the future. It is easy to use, can realize online replacement and online maintenance, and reduces maintenance difficulty and reduces Maintenance time. The dimensions of each module are designed according to the standard 19-inch structure, so that the shape of the whole machine is consistent with the standard frame, the appearance of the machine is beautified, and the module can be used with the standard frame.
6, redundancy, decentralized parallel logic control
Parallel control between modules adopts decentralized logic control. There is no master or slave. No module can be dialed or inserted to affect the normal operation of other modules. N+1, N+X are required as needed. The redundant system reduces the risk factor of the system itself and the load, and the load is fully improved by the UPS protection time. It not only increases the reliability of the whole machine, but also simplifies the maintenance of users.
