Modular UPS power supplies include rectifiers, inverters, static bypass switches, and auxiliary control circuits, CPU main control boards, etc. The biggest advantage of modular UPS power supplies is their improved system reliability and availability. A failure in any module will not affect the normal operation of other modules, and the hot-swappable feature shortens system installation and repair time. The system structure of modular UPS power supplies is highly flexible. The design concept of power modules allows for easy removal and installation during system operation without affecting system operation and output, enabling "on-demand expansion" of investment planning and "dynamic growth" for users as their business develops. This satisfies the need for future equipment expansion while reducing initial purchase costs.
1. Offers multiple work modes
This modular UPS power supply offers a variety of options, is easy to operate, and supports multiple input/output wiring configurations: 1/1, 1/3, 3/1, or 3/3. The input frequency can be set to 50Hz, and the output frequency can be set to 60Hz. The output voltage can be set to 220V, 230V, or 240V. With the addition of input and output transformers, it can meet the power supply needs of all countries and regions worldwide. Its most prominent features are its small size, high power density, and high efficiency. It can provide power outputs of 5KVA (4000W), 10KVA (8000W), 15KVA (12KW), and 20KVA (16KW).
2. Environmental friendliness
The UPS has a total harmonic distortion (THDI) of 3%, and less than 2% under linear load, minimizing harmonic interference to the power grid and effectively reducing grid load and power loss. Its excellent input parameters exhibit pure resistive characteristics to the mains power grid, making it an ideal environmentally friendly and efficient UPS.
3. High-efficiency and energy-saving type
In today's era of energy conservation and emission reduction, and with the nation advocating for environmental protection and energy saving, green and energy-efficient modular UPS systems are receiving increasing attention, boasting an input power factor of over 0.999. This reduces line losses and improves power utilization. Their inverter efficiency can reach over 98%, thereby improving overall system efficiency, reducing losses, and saving energy.
4. Expandability, facilitating installation, maintenance, replacement, and upgrades.
This model consists of various modules that allow for hot-swapping, and each module rack can be completely separated, facilitating future capacity expansion or reduction. It is easy to use, enabling online replacement and maintenance, reducing maintenance difficulty and time. Furthermore, each module is designed according to a standard 19-inch structure, making the overall machine appearance consistent with standard racks, improving its aesthetics, and ensuring module compatibility with standard racks.
5. Redundancy, distributed parallel logic control
The parallel control between modules adopts a distributed logic control method, without the distinction between master and slave units. The removal or insertion of any module will not affect the normal operation of other modules. This allows for the construction of N+1 or N+X redundant systems as needed, reducing the risk factor for the system itself and the load, and comprehensively improving the UPS protection time for the load. This increases the overall reliability of the unit and simplifies user maintenance.
