1.5v Dry Battery.UPS uninterruptible power supply working method and wiring precautions

　　UPS uninterruptible power supply working method and wiring precautions. UPS uninterruptible power supply system has a wide range of applications. It is mainly used in supermarkets, shopping malls, banks and other enterprises and institutions. It can not only stabilize the voltage, but also prevent data loss. There are many UPS power supply brands, and different brands have different performance advantages. For this reason, for the majority of users, when using UPS power supplies, in order to better utilize the performance of the power supply, they should have an understanding of the relevant working methods.

　　How UPS uninterruptible power supply works

　　1. Normal operating mode; Normal operating mode mainly refers to the UPS uninterruptible power supply system. When the mains power is in a normal state, the machine will convert the alternating current of the mains power into direct current, and then charge the battery as a backup power supply for backup. Used during power outages. Of course, it needs to be clear at this time that the uninterruptible power supply system can work even if there is no power outage. For example: low voltage, instantaneous surge, etc. will affect the normal operation of the equipment. When the UPS system is in working condition, the corresponding load equipment will provide stable and clean power.

　　2. Battery working mode: Once the mains power is abnormal, the DC power stored in the battery is converted into AC power. At this time, the input of the inverter is supplied by the battery pack. The inverter continues to provide power and the load continues to be used. Achieve continuous power supply function. The power source of the UPS power system is the battery, and the capacity of the battery is limited. Therefore, the UPS system does not continuously supply power like the mains power. Therefore, no matter how large the capacity of the uninterruptible power supply system is, when it is fully loaded, all its The power supply time must be limited. If you want to extend the discharge time, you must purchase a long-delay UPS power supply.

　　3. Bypass operation mode; mainly refers to when the emergency power supply is overloaded or the machine fails. At this time, the UPS uninterruptible power supply will invert the output and convert it into a bypass output, that is, direct power supply from the city power. Currently, there are many places producing UPS power supplies, among which Shenzhen UPS power supplies are very popular among consumers.

　　4. Bypass maintenance mode. When the UPS power supply is undergoing maintenance, manually set the bypass to ensure normal power supply to the load equipment. When the maintenance operation is completed, restart the UPS power supply, and the UPS power supply will return to normal operation at this time.

　　UPS power wiring precautions

　　1. Confirm how much DC voltage the UPS needs to be connected to

　　2. Connect the batteries in series or parallel to get the required voltage

　　3. Make sure the positive and negative poles are connected

　　4. The connection method of each battery in each battery group is: series connection

　　5. The connection method between each group of batteries and other groups of batteries (ie: group to group) is: parallel connection

　　6. It is strictly prohibited to "connect" batteries from different groups together in series

　　Misunderstandings in purchasing UPS power wiring diagram

　　The maintenance-free battery is the most important component of UPS power supply, and its cost is also the highest among the entire product. However, in order to make illegal profits, some businesses often replace the maintenance-free batteries in mid-to-high-end UPS power supplies with batteries of other brands or counterfeit brands, and then sell the maintenance-free batteries of the removed brand UPS power supplies separately. If you trade this for one, the profit is quite astonishing. Just like everyone is very familiar with the replacement of mobile phone batteries, why are the mobile phones in those humble stores cheaper than those in big stores, but the original accessories they sell are not cheap at all? This is the problem. The damage caused by inferior batteries is not trivial, mainly manifested in short inverter time and insufficient power supply.

　　Can the UPS power supply be connected to an external socket?

　　The UPS power supply can be connected to an external socket, but there are a few points to note:

　　1. The total power of the electrical appliances used in the external socket and the original electrical appliances of the UPS cannot exceed 70% of the UPS capacity.

　　2. Do not plug in inductive loads such as motors, such as impact hammers, hair dryers, vacuum cleaners, etc.

　　3. The quality of the external socket itself should be good, and products from regular manufacturers should be selected.

　　4. Prevent dust and water from entering the socket and causing short circuit or leakage.

　　5. If it is not used for a long time, the external socket should be unplugged to prevent others from misuse.

　　How to use UPS uninterruptible power supply

　　1. Before starting up, make sure the polarity of the input mains wiring is correct. The UPS system has very strict requirements for the positive and negative poles of the power supply. If you are not careful, the consequences will be disastrous.

　　2. Pay full attention to the fact that the total load capacity cannot be greater than the rated power of the UPS. If the total load capacity is too large, the battery in the UPS will be overloaded. Over time, the battery will be damaged and even the UPS will be damaged.

　　3. After the mains power is interrupted and the UPS is powered by the battery and automatically shuts down, do not use the UPS battery for power supply. Excessive discharge will only rapidly reduce the battery life of the UPS.

　　4. When an abnormality occurs in the mains power supply and the UPS switches to battery power supply, the computer system under load should be shut down immediately. Do not assume that the battery life is long enough, and continue to play games or work even during the power supply period.

　　5. Unless the UPS itself has been marked, do not connect an external long-lasting battery. Doing so will cause the UPS to malfunction due to increased power.

　　6. Please do not place magnetic objects such as magnets on the UPS, otherwise it will easily cause the data in the memory of the UPS to be lost, making the machine unable to complete its intended functions.

　　As an important computer equipment, UPS uninterruptible power supply is very important in protecting computer data, ensuring the stability of power grid voltage and frequency, improving power grid quality, and preventing harm to users caused by instantaneous power outages and accidental power outages. The above is a detailed explanation of the UPS wiring diagram and four working methods. I believe everyone has a rough understanding. You still need to carefully compare this knowledge in daily work, so that it will be easier to master.
