Advantages of Modular UPS Power Supplies
Release time:
2019-02-20
A modular UPS power supply comprises a rectifier, an inverter, a static bypass switch, and associated control circuits and a CPU-based main control board. The greatest advantage of a modular UPS power supply is its ability to enhance system reliability and availability. If any single module fails, it will not affect the normal operation of other modules. Moreover, thanks to its hot-swappable feature, the system’s installation and repair time can be significantly reduced. The system architecture of a modular UPS power supply is highly flexible; the power modules are designed in such a way that they can be freely removed and installed during system operation without disrupting the system’s performance or output. This allows for “on-demand scalability” in investment planning, enabling users to expand their systems as their business grows.

Advantages of Modular UPS Power Supplies (Optimal Performance Features of Modular UPS)
1. Features multiple operating modes
This modular UPS power supply offers a variety of standard configurations to choose from, is easy to operate, and supports multiple input and output wiring options: 1/1, 1/3, 3/1, or 3/3. The input frequency can be set to either 50 Hz or 60 Hz, and the output voltage can be configured to 220 V, 230 V, or 240 V. By additionally equipping it with input and output transformers, this UPS can meet the power supply requirements of virtually every country and region worldwide. Its compact size, high power density, and exceptional efficiency are its most notable features. It provides power outputs of 5 kVA (4000 W), 10 kVA (8000 W), 15 kVA (12 kW), and 20 kVA (16 kW).
2. Environmental friendliness
The UPS has a total harmonic distortion (THDI) of 3%, and the output total harmonic distortion under linear loads is below 2%. This minimizes harmonics injected into the power grid, effectively reducing grid load and power losses. With excellent input parameters, the UPS exhibits purely resistive characteristics when connected to the utility grid, making it an ideal, environmentally friendly, and highly efficient UPS.
3. High-efficiency and energy-saving type
In today’s era, when the nation promotes environmental protection and energy conservation, green, energy-efficient, modular UPS systems have attracted considerable attention. These systems achieve an input power factor of 0.999 or higher, reducing line losses and improving power utilization efficiency. Moreover, their inverter efficiency can reach over 98%, thereby enhancing overall system performance, minimizing losses, and saving electrical energy.
4. Scalability, easy to install, maintain, replace, and upgrade.
This model consists of individual modules that support hot-swappable functionality. The modular racks can be completely separated, making it easy for users to expand or reduce capacity as needed. It is user-friendly and allows for online replacement and maintenance, thereby reducing maintenance complexity and shortening maintenance time. Moreover, all module dimensions are designed according to the standard 19-inch rack format, ensuring that the overall machine appearance matches that of a standard rack, enhancing the aesthetic appeal of the device. Additionally, these modules are fully compatible with standard racks.
5. Redundancy, distributed parallel logic control
The parallel control among the modules adopts a distributed logic control approach, eliminating the distinction between master and slave modules. Inserting or removing any single module will not affect the normal operation of other modules. By configuring systems with N+1 or N+X redundancy as needed, we can significantly reduce the risk factors associated with both the system itself and its load, thereby comprehensively enhancing the duration of load protection by the UPS. This not only boosts the overall reliability of the system but also simplifies user maintenance tasks.
