By: www.sales-battery.com UPS (uninterruptible power supply) is a common auxiliary equipment, currently used mainly back-type external UPS, 500W and 1000W power there are two. The wattage does not mean that the maximum output power, nor how many devices can be driven, but when the external power to stop power supply, UPS can provide much electrical energy output, that is, the greater capacity of the UPS, can provide power to more. Because energy is usually stored in the battery in, so more power to UPS, generally requires an external one or more batteries. Usually sold on the market is back type UPS, the price is moderate, stop the external power or voltage is too low, it will be in a very short period of time into battery. UPS 500W of desktops in general can continue to work 7-15 minutes. There is also a known on-line UPS, I usually keep to an external power supply battery charging, and inverter circuit has been working within, the direct current into alternating current supply equipment again. The UPS output voltage accuracy is high, but less than the efficiency of power-type back, because power in the rectifier and inverter in the process, there will be some loss of power, mainly converted to heat by. So often with this UPS fan, and this UPS is very expensive, only suitable for use in areas with high voltage accuracy required. UPS Using People know that riding a motorcycle, car lead acid battery in the process of vehicles is constantly charging, the charging current is small, but as long as the car is moving on, charging time is longer, the charging process is called "float." If the float current is not enough, the discharge of many words, the battery will "lose power." Long-term loss of power when the battery runs the case, lead plates of lead sulfate will have a lot of attachment, resulting in very difficult again electrolysis, the charge becomes very difficult, the battery capacity will be significantly reduced, a phenomenon commonly known as "poisoning." UPS is also a lead-acid batteries in use, but made a good sealed maintenance- On the other hand, UPS, when no external power supply must be able to open and close, which requires the circuit when the battery must have sufficient voltage. In UPS, the batteries are consumables, so the battery can be purchased separately. To more than a few years of your UPS, it is best to protect the inside of the battery. The best maintenance methods, is to keep the UPS is always open, keep the battery in sufficient electricity. Another point, the battery storage capacity limit, do not be too much on the equipment connected to the UPS, so when the battery power will soon be exhausted. UPS AC output side of the fuse is only 10A, so no air-conditioning, electric and other large power equipment, UPS pick on. General packaging instructions have a spare bag fuse, be careful not to lose, if not the same fuse replacement, absolutely do not used copper wire instead. Maintenance Have a general knowledge of electrical maintenance person can UPS. Maintenance of attention to safety on it. UPS failures are generally divided into the following categories: damage to electrical components, batteries lose power, bad connectors, and so on. 1, the electrical component damage is generally not common, if the rectifier and inverter circuit who are not familiar with the various components can be observed there is no cracking, leakage and other methods to judge. If you have some electrical knowledge, people can use multimeter to measure. UPS is not on the complexity of the circuit, with eyes to see the role and part of the relay works. 2, the battery power loss is better judgments. If UPS does not start, most of battery. Can remove the UPS case, direct measurement with a multimeter battery terminal voltage, if less than the rated 60%, that the battery power shortage. Note the difference between no-load and load, if not start the UPS when the battery voltage is relatively high, according to a switch to the battery voltage becomes too low, which is also the battery power loss. I usually use a small wire to short the end of a relay to allow UPS to force start charging circuit while doing so began to work. If the battery charge would also be able to continue, it means there is a save the battery. If sufficient power is not increased for several hours, then this battery can be declared obsolete. This method was to follow if you want, then please confirm your correct and safe. 3, the battery inside the plug connector and plug the transformer's output connectors are likely to loose. Than the former, UPS can not work during power outages, which can cause alarm and can not supply. Summary: Want to fix a UPS must be cautious, because UPS has a reverse into the function of electricity, maintenance, must pay attention to safety. 【sales-battery.com】 The Second Largest Battery Supplier On US Market TOSHIBA PA3383U-1BRS Battery http://www.sales- dell inspiron e1505 battery http://www.sales- COMPAQ PRESARIO 2100 Battery http://www.sales- # # # The Second Largest Battery Supplier On US Market We are capable to provide High Quality laptop batteries, camcorder Batteries, camera batteries, adapters and chargers in United States . 30% discount now !!!
