UPS power supply, as a backup energy storage power source for large companies such as shopping malls, supermarkets, banks, and base stations, has a crucial and superior position. In addition to its function of protecting equipment from power outages, it also plays a role in stabilizing voltage. So with UPS power supply, our work and daily life are well-organized. However, maintenance is often overlooked, and people believe that UPS power supply is maintenance free, but do not pay attention to it, thereby reducing the service life of UPS.
Santak UPS power supply is an uninterruptible power supply that includes rechargeable batteries and can provide voltage regulation for electrical equipment. Rated output power is an important parameter that indicates how much power a product can drive. It varies with the load power factor. For example, a 1kVA UPS may not be able to drive a 1kVA load. In order to extend the service life of UPS, it should not operate at full load for a long time.
Backup UPS generally selects loads with a rated power of 60% -70%, while online UPS generally selects loads with a rated power of 70% -80%. It is also not advisable to operate under excessively light loads for a long time. UPS should not be fully loaded or overloaded. Each unit is labeled with its rated power. Generally speaking, online UPS should not exceed 80% of its rated power. Therefore, do not use according to the nominal rated power. Causing overheating of inverters and rectifiers, affecting their service life.
Similarly, it is not advisable to operate under excessively light loads, as such loads may cause the battery to discharge deeply during power outages, significantly reducing its lifespan. For some special loads, strong surge currents will be generated during startup or operation, and the load capacity will instantly increase several times (sometimes up to six times). For such loads, the margin should be further increased on the basis of the normal capacity margin ratio.
The correct capacity ratio has a significant impact on the normal and stable operation of UPS and its service life. The probability of UPS system failure that frequently operates under full load or overload conditions is higher than the correct capacity ratio.
Under normal room temperature conditions and normal use, the float charging service life of sealed maintenance free lead-acid batteries for Santak UPS power supply is generally 3-5 years. However, many human factors can greatly shorten the lifespan of UPS power supplies. It can be seen that improper maintenance of UPS power supply can affect the normal service life of ADW. Therefore, there are several precautions to be taken.
1. The battery usage environment requires a temperature between 0 and 40 degrees Celsius, avoiding direct sunlight and keeping it clean.
2. Normally, the battery should be charged and discharged every 3-6 months, and the charging time of the standard machine should not be less than 10 hours after discharge.
3. If the UPS power supply is idle for a long time, it should be charged every 3-6 months.
