How to maintain the classification of uninterrupted power supply? How to maintain the UPS power supply? There are a lot about the type of power supply. Do you know anything in the uninterruptible power supply, what is the classification of uninterrupted power? At present, there are many uninterruptible power supply UPS systems in the domestic and foreign markets. Its important function is basically the same, and the following small compilation is simple to analyze its use and maintenance.
Uninterrupted power supply classification UPS uninterrupted power supply is divided into rear preparation according to working principles, online interactive formula three categories. 1. Backup UPS, it has the most important function of automatic voltage regulation, power-off protection, etc.
Widely used in microcomputer, peripherals, POS machines and other categories. Backup UPS power supply is divided into rear-standing sine wave output UPS power supplies and rear-standing square wave output UPS power supplies. Rear-standing sine wave output UPS power supply: single output can be 0.
25kW ~ 2KW, when the market is changed between 170V ~ 264V, supplied to the user to solve the urban electricity in the regulator; when the market exceeds 170V ~ 264V When it is supplied from UPS to high quality sine wave power supply. 2. Online UPS uninterruptible power supply structure is more complicated, but performance is perfect, can handle all power problems, such as four-pass PS series, its salient feature is to continue to output a pure sine wave alternating current in zero, can handle spikes, surge, Frequency drift and other power problems; due to large investment, usually use the demanding environment in key equipment and network centers, etc.
3. Online interactive UPS, compared with the same backup, the online interactive type has filtering function, and the anti-market interference ability is very strong, the conversion time is less than 4 ms, the inverter output is analog sine wave, so it is possible to equip the network equipment such as a server, router. Or use in a harsh region in the power environment.
How to maintain the UPS power supply? UPS power maintenance generally has the following: 1, daily inspection appearance, regular replacement of battery, filter capacitor, fan, etc., is a battery activation, etc. 3, regularly conduct power test alert leakage, etc.
● Do a good job in dustproof work, fragmentation and dust from the UPS power supply. Through daily accumulation into the UPS inside, first cause the body temperature to damage the UPS components, and the second dust accumulation will cause the UPS motherboard and power board contact failure, resulting in UPS overload run. ● When there is no external electricity to supply it from the UPS power system, it should be turned off first, and the UPS power system is turned on and then turned on to prevent the load to start the UPS power supply.
● It is well known that the number of excessive discharges of the UPS power supply should be minimized during operation, because over-discharge number is directly affected battery life. ● For the battery unit for alert UPS power, the UPS power supply is prematurely damaged because the UPS power supply should be arranged as much as possible to make the battery charging time at night, thus ensuring sufficient time and stable battery after discharge. Voltage charging battery.
UPS uninterrupted power supply is a desired power supply equipment, during use, maintenance is a very important job, it is possible to prevent machine failure. The necessary maintenance of the UPS power battery pack is the key to extending the service life of UPS.
