What is UPS Battery Backup Used For?

UPS, also known as an uninterruptible power supply, is a constant voltage and constant frequency uninterruptible power supply with the energy storage device and inverter as the main component. It mainly provides uninterrupted power supply to a single computer, computer network system or other power electronic equipment. When the mains input is normal, the UPS will stabilize the mains and supply it to the load. At this time, the UPS is an AC mains voltage stabilizer, and it also charges the battery inside the machine. When the mains power is interrupted (accidental power failure), the UPS will immediately supply the 220V AC power to the load by inverting the power of the battery in the machine, so that the load can maintain normal operation and protect the software and hardware of the load from damage.

UPS functions

In the early days of its development, UPS was only regarded as a backup power source. Later, due to voltage surges, voltage spikes, voltage transients, voltage sags, continuous over voltage or under voltage or even voltage interruptions and other ethylene-based power grid quality problems, the electronic systems of computers and other equipment were disturbed, resulting in damage to sensitive components and information. Loss, disk programs are flushed, etc., which cause huge economic losses. Therefore, UPS has been paid more and more attention and has gradually developed into a power protection system with functions such as voltage regulation, frequency stabilization, filtering, anti-electromagnetic and radio frequency interference, and anti voltage surge.

Tips for using UPS

When using the line-interactive UPS, the relevant provisions of the manufacturer's product manual should be strictly followed to ensure that the order of the live wire and neutral wire of the mains connected to the UPS meets the requirements.
The main purpose of UPS is to prevent the computer from losing information and destroying the hard disk due to sudden power failure, but some equipment is not afraid of sudden power failure when working. In order to save the energy of the UPS, the printer can consider directly connecting to the utility power without going through the UPS. If it is a network system, consider that the UPS only supplies power to the host (or server) and its related parts. This ensures that the UPS can be used on the most important equipment and saves investment.
Do not overload the UPS. The maximum load of the UPS power supply should be 80% of its nominal load. If overloaded, in the inverter state, it will often cause the breakdown of the inverter triode. In addition, when using UPS, it is strictly forbidden to connect inductive loads such as fluorescent lamps, but only pure electric or small capacitive loads.
Pay attention to the sequence of switching on and off when switching on and off.
When starting up, turn on the UPS first, and then turn on the power switch of the load later. Note that the power switches of the load should be turned on one by one.
When shutting down, the sequence is just the opposite, first turn off the power switch of the load one by one, and then turn off the UPS. The UPS needs to be turned on for a long time, while the computer and other loads need to be turned on each time it is used. After use, just turn off the power switch of the computer and other loads.
Do not turn off and on the UPS power frequently.
It is generally required to wait at least 6 seconds before turning on the UPS power supply after turning off the UPS power supply. Otherwise, the UPS power supply may be in a state of "failure to start". At this time, the UPS is in a state of no mains output and no inverter output. normal status.
The electric energy in the battery in the UPS may be exhausted for some reason. In order to compensate for battery energy and improve battery life, the UPS needs to perform timely, long-term continuous charging to avoid failure due to battery failure. Charging is usually no less than 48 hours, with or without load.
