What Is UPS?
UPS is a device that continues to supply power to connected devices for a certain period of time in the event of a power failure.
UPS stands for "Uninterruptible Power Supply." It has a built-in battery and supplies power to electronic devices such as servers, PCs, and network equipment to prevent problems in the event of input power failure such as electric outage or power supply trouble.
Uses for UPS
UPSs are used in a variety of locations to provide appropriate countermeasures on the power demand side in the event of power supply fluctuations due to power transmission path failures, power outages caused by natural disasters, and power supply switching during large-scale construction projects.
UPSs can delay power interruptions for several minutes, allowing electronic equipment to perform normal termination processes during this time and avoid breakdowns. Specific uses include personal computers, office automation equipment, and network equipment in offices, and POS terminals, customer information terminals, security, and disaster prevention-related equipment in stores.
In call centers and data centers, it is used for PCs, servers, communication equipment, and air conditioning equipment. UPSs are used in a variety of fields to protect power supplies and ensure stable operation.
Depending on the model, UPSs can be combined with power management software to automatically and safely shut down or start up equipment in the event of a power failure.
Principle of UPS
A UPS generally consists of the following circuits and batteries:
- Converter
A circuit that converts AC power to DC power. - Inverter
A circuit that converts DC power to AC power. - Bypass
A circuit that outputs AC power directly. - Switch
Circuit to switch between inverter output and bypass output.
UPSs are available in a variety of power supply methods, the three most common of which are as follows:
1. Constant Inverter Power Supply System
This is a method in which power is supplied through an inverter regardless of the state of the commercial power supply. Power is supplied by the inverter under both normal and blackout conditions. This method eliminates noise, etc., while providing a stable power supply at all times.
2. Line Interactive Method
This method supplies power from commercial power during normal operation and at the same time charges the battery via an inverter. In the event of a power failure, the system switches to inverter power supply, but since power is still supplied to the inverter during normal operation, the switching time is shorter than that of the constant commercial power supply system.
3. Constant Commercial Power Supply System
This system supplies power directly from the commercial power source during normal operation and switches to inverter power supply from the battery during a power failure. Since the inverter is stopped during normal operation, this is a power-saving system, and since it uses fewer circuits, it has the advantage of being compact and inexpensive.
On the other hand, it is not suitable for connection to equipment that requires stability because a momentary power loss of several milliseconds may occur when switching the power supply.
Other Information on UPS
1. Service Life of UPS
UPSs have service lives and generally need to be replaced after about 5 to 6 years; since UPSs are constantly energized, the electrolytic capacitors and other components inside them are susceptible to failure, and it is recommended that long-term use beyond their service life be avoided.
It is important not to use UPSs past their standard service life, as they may catch fire as they deteriorate over time. Periodic inspections are also essential, as their service life will be shortened if they are used in environments with high temperatures.
2. The Battery of the UPS
UPSs are equipped with a battery that supplies power to connected devices in the event of a power outage.
The MSE type is relatively large in size and is mainly used for high-capacity applications, while the UPS-only type can be installed in a space-saving manner. The MSE type is generally larger in supply capacity.
As batteries are used, their charge capacity decreases. It is recommended that they be replaced when their charge capacity drops below 80%.
Many models are equipped with LED lamps to indicate battery deterioration. Most products have batteries that can be replaced without specialized knowledge.
