With social development, we have become accustomed to 24/7 power supply and feel greatly inconvenienced when it's unavailable.
A UPS main unit is an AC power source primarily composed of rectifiers and inverters. Its core function is to solve power outage problems and ensure business continuity.
I. Core Functions of UPS Main Unit
1. Uninterrupted Power Supply
When mains power suddenly fails, the UPS main unit can switch the load to battery power within zero transfer time, ensuring continuous equipment operation. This seamless transition prevents computer data loss due to unexpected power cuts while maintaining system operation.
2. Voltage Stabilization & Power Purification
The UPS features voltage regulation capability, automatically adjusting voltage to protect equipment from grid fluctuations. Simultaneously, it filters out grid harmonics to deliver cleaner power.
3. Remote Monitoring
Some UPS units come equipped with monitoring systems, allowing users to remotely check parameters like voltage, current, and load status.
Rack-mounted UPS main units adopt online double-conversion technology, achieving true zero-transfer time to safeguard critical equipment. Their standard 19-inch rack design facilitates easy installation in server cabinets.
II. Selecting the Right UPS Main Unit
Consider these factors when choosing a UPS:
1. Type Selection Based on Load
Different UPS types suit different needs. Standby UPS provides basic functions like power outage protection. Though featuring a 4-8ms transfer time, its simple structure makes it cost-effective.
Online UPS has more complex structure but superior performance, with the distinct advantage of continuously outputting pure sine wave power. However, the corresponding higher price makes it typically suitable for demanding environments like network centers.
2. Capacity Planning
Ensure selected UPS capacity sufficiently supports all connected devices while considering backup time requirements.
Hope this information helps you choose the most suitable UPS main unit!
