Anonymous users2024-02-06Since the UPS is the control gate of the mains to the load, its design itself is very complex, it is a relatively delicate thing, and it is more prone to failure. In addition, a considerable number of individual users do not pay attention to the use, which makes UPS even more problematic. Therefore, in order to reduce the probability of UPS failure, it must be used and maintained correctly, so as to maximize the use time of UPS.
1. Before starting, it is necessary to confirm that the polarity of the input mains wiring is correct, and the UPS system has very strict requirements for the positive and negative poles of the power supply.
2. Pay full attention to the total load capacity should not be greater than the rated power of UPS. If the total load capacity is too large, the battery in the UPS will be overloaded, and the battery will be damaged or even damaged in the UPS for a long time.
3. After the mains power is interrupted, after the UPS is powered by the battery and automatically shuts down, do not use the UPS battery for power supply, excessive discharge will only reduce the battery life of the UPS rapidly.
4. When the mains power is abnormal and the UPS is converted to battery power, the computer system in the load should be turned off immediately, and do not think that the battery has been used long enough, or even continue to play games or work during the power supply period.
5. Unless the UPS itself has been indicated, do not connect an external long-lasting battery, which will cause the UPS to fail due to increased power.
6. Please do not put magnetic objects such as magnets on the UPS, otherwise it will easily lead to the loss of data in the memory of the UPS machine, so that the machine can not complete its due function.
7. UPS is more suitable for capacitive loads, but not for inductive loads (such as air conditioners, hair dryers, electric rotation), half-wave loads and impact loads (such as printers), and UPS with square wave output cannot be charged with inductive loads.
8. UPS should not be operated in a full load or light load state all the time, and 50%-80% of the rated capacity is generally selected. When purchasing, please refer to the previous announcement to purchase.
9. Do not turn off and on the UPS power frequently. Generally, it is necessary to turn off the UPS power for 6 seconds before turning it on again, otherwise the UPS power may be in"Failed to start"That is, the UPS power supply is in a state where there is neither mains output nor inverter output.

Anonymous users2024-02-05The use of UPS uninterruptible power supply is as follows:
Send mains power to UPS so that it is in bypass work.
Turn on the loads one by one. First turn on the load with a larger inrush current, and then turn on the load with a smaller inrush current, and the UPS panel is turned on to make it in the inverter working state.
Properly connect the voltage polarity of the battery.
Do not connect the cable between the battery and the main unit first, and wait for the UPS mains input to generate a charging voltage before connecting.
Turn off the loads one by one, and then turn off the UPS panel. If you need UPS output, turn off the UPS completely.

Anonymous users2024-02-04The role of UPS is as follows:
1. Power failure protection.
When the mains power grid is instantaneous, the UPS uninterruptible power supply system will immediately convert the DC power supply of the UPS battery into alternating current to continue to supply power to the load, so as to avoid the inconvenience and loss caused by the power failure.
2. Voltage stabilization.
The mains voltage is easily affected by the distance and quality of the power transmission line, and the voltage of users who are closer to the substation is higher, and the voltage of the households that are far away from the substation will be lower and lower. Too high or too low voltage will affect the quality and service life of the user's instruments and equipment, and in more serious cases, it will damage the equipment and cause heavy losses to the user.
3. Surge protection.
Generally, the UPS power supply system will have a cutting-edge discharge design to absorb surges, so as to avoid the impact on the efficiency and life of the equipment due to surge problems, and provide protection for the equipment.
An overview of UPS is as follows:
UPS, that is, uninterruptible power supply, is a kind of uninterruptible power supply with constant voltage and constant frequency containing energy storage devices and inverters as the main components. Its main function is to provide uninterrupted power to a single computer, computer network system or other power electronic equipment**. When the mains input is normal, the UPS uninterruptible power supply will provide load use after the mains voltage is stabilized, and the UPS uninterruptible power supply at this time is equivalent to an AC mains voltage regulator, and it also charges the battery in the machine; When the mains power is interrupted, UPS will immediately transfer the power of the battery in the machine to the load through the method of inverter conversion, and continue to use 220V alternating current to maintain the normal operation of the load and protect the load from damage to the software and hardware.
Installation Precautions 1The area where the UPS is placed should be well ventilated, away from dangerous goods such as water, flammable gases, corrosives, etc., and the installation environment should meet the requirements of product specifications. 2. >>>More
UPS power supply refers to an uninterruptible power supply, which is a system equipment that connects the battery to the host and converts direct current into mains power through module circuits such as the host inverter. It is mainly used to provide stable and uninterrupted power supply for a single computer, computer network system or other power electronic equipment such as solenoid valves and pressure transmitters. >>>More
If you talk about reasonableness, of course, it is an independent power supply and does not directly use a 12V battery ** each camera without UPS inverter. The unified power supply circuit is simple, but the cost of UPS is significantly higher due to the high power and battery life of UPS. I think the appropriate solution is to equip each camera with a 12V power supply according to the backup requirements and use a relay to supply power to it. >>>More
1. Backup type: When the early backup UPS power supply is normal, the mains power supply is directly supplied to the load through the AC bypass and transfer switch, the AC bypass is equivalent to a wire, and the inverter does not work, so the power supply efficiency is high but the quality is poor. In recent years, the backup UPS is often equipped with AC voltage regulator circuit and filter circuit on the AC bypass circuit to improve. >>>More
The nominal unit of measurement of power of UPS is: KVA (kilovolt ampere), and the nominal unit of power supply time is: H (hour); The nominal unit of quantity is: sets.
