With the development of global diversification, our lives are constantly changing, including all kinds of electronic products we have exposed, then you must not understand some of these products, such as UPS power. UPS power failure is the fierce behind most UPS disasters. Although the UPS power is easily damaged, users don't have to be victims.
The following content will introduce five important reasons for UPS's overeatment, and how to prevent such faults. When the alternate UPS power is usually powered by the main power, the main electricity is directly connected by the AC, and then the inverter in the machine is stopped by the conversion switch. This UPS power is essentially equivalent to a city electric regulator with extremely poor regulating performance.
In addition to improving the amplitude fluctuation of the power supply voltage, it does not improve the unstable power voltage frequency unstable, waveform distortion and power grid interference. Only when the main power is interrupted or less than 170V, the battery is powered for the UPS inverter and supplies adjustment and frequency stable AC power supplies for the load. The advantages of the alternate UPS power supply are high running efficiency, low noise, relatively cheap.
Important is suitable for applications where the city electricity is not large, the power supply quality is not high. What is a UPS power supply? After the main electricity is normal, the online UPS power supply first converts the electricity of the electricity electricity to direct current. Factors and maintenance methods that lead to premature failures of UPS power supply: No measures are taken to prevent UPS power supply from reaching its life.
However, prevent the following errors can help ensure life life. 1. Unused UPS power supply is poor storage - even if the UPS power supply is not used, its life will begin to decrease.
This is because the lead-acid UPS power will automatically release a small amount of energy. In order to extend the storage life of the UPS power supply, it is recommended to charge it once every three to four months. If you don't do this, you may see a permanent capacity loss in just six months.
You can also extend the life of unused UPS power supplies at 50 ¡ã F (10 ¡ã C) or lower temperatures. 2. Higher ambient temperature - Rated capacity of each UPS power supply based on ambient temperature of 25 ¡ã C (77 ¡ã F).
Any change (especially temperature increase) affects performance and service life. Typically, the recommended ambient temperature is 15 ¡ã F per liter, and the expected life of the UPS power supply will be reduced by 50%. Routine maintenance check can help find hotspots and verify ventilation.
Whether the frequency range of the input power supply is wide, whether it has super strong lightning power, whether it has anti-electromagnetic interference capabilities, etc., it must be considered when selecting UPS. In the case of small capacity or part of the power, what functional indicator should be considered when selecting UPS? For small capacity or partial power, first select small capacity UPS, then select online or online mode according to its power quality requirements.
Alternate UPS. Alternate UPS has 500VA, 1000VA, online type with 1kva to 10kVA for users to choose. What functional indicators should be considered when choosing a large capacity or a centralized power supply? For large power or centralized power, you should choose a large-capacity three-phase UPS.
And consider whether there is 1 output short circuit protection; 2 can be connected to the unbalanced load; 3 with isolation transformers; 4 can be used as a hot backup; 5 multi-language graphics liquid crystal display; 6 remote monitoring; 7 super monitoring software. 3. This time period is too long, because the UPS power supply will be charged for future use during the power failure period, this is called the discharge time.
After installing the UPS power supply, the UPS power will reach 100% of its rated capacity. However, each discharge and subsequent charging will slightly reduce the capacity of the UPS power supply. 4.
Floating voltage errors - Each UPS power manufacturer will designate the charging voltage range for its own UPS power supply design. If the UPS power continues to charge outside these parameters, it may cause serious damage to damage. Insufficient charge or high voltage can result in a sulfate crystal on the UPS power board.
Over time, these crystals will harden and reduce the available capacity of the UPS power supply. Excessive floating voltage can lead to excessive hydrogen and oxygen, and may result in internal drying. Once accelerated, the internal drying will cause thermal out of control, resulting in failures or even fire.
5. UPS power supply is not correctly used for UPS, just like other UPS power supplies to its respective devices. The UPS power supply can supply extremely high energy consumption in a short time (usually 15 minut.
