the UPS power supply needs to be regularly discharged during daily use to extend its service life. Generally, it needs to be charged and discharged once every three months.
I. UPS Discharge Precautions
1. First, understand how long the UPS power supply can provide backup power to prevent the discharge time from exceeding the backup time, which could cause the load to fail and damage the equipment.
2. Visually inspect the battery for obvious deformation and leakage.
3. If the power supply itself has an automatic discharge function, it is recommended to use it directly.
4. When manually discharging, please constantly observe the drop in UPS battery voltage so that you can restore mains power input at any time.
5. When discharging, it is best to discharge to two-thirds of the rated capacity. Discharging is mainly to activate the battery and extend its service life.
6. For medium to high power UPS power supplies, the rectifier and bypass input switch are usually designed independently. It is recommended to turn off the rectifier switch instead of turning off the user’s AC input switch. This will prevent the UPS from immediately switching to bypass mode in case of battery discharge failure.
II. Precautions for UPS Power Supply Environment
1. Clean environment
UPS power supplies are very clean and particularly susceptible to dust. When a UPS operates in a dusty environment for a long time, it is prone to malfunction. This is because dust can quietly “get into” the UPS control frame and directly cover its electronic circuitry. Over time, the internal circuitry of the UPS will suffer from poor heat dissipation, which will naturally lead to failure.
2. Avoid dampness
UPS power supplies are also susceptible to moisture. After all, UPS contains electronic circuits. When the various components in the electronic circuits work in a humid environment for a long time, their electrical performance will gradually decline, and there is also a possibility of leakage, which could lead to a fire.
3. Prevent being surrounded by strong magnetic fields
UPS power supplies should not be placed in environments surrounded by strong magnetic fields. In other words, they should not be placed near equipment with strong magnetic properties, because UPS uninterruptible power supplies have very limited inherent anti-magnetic capabilities. If they are used in a strong magnetic field environment for a long time, the lifespan of the UPS power supply will be greatly shortened!
4. Optimal operating temperature
UPS power supplies are also very sensitive to ambient temperature. Environments above 40℃ or below 0℃ will reduce their “activity” and, in particular, prevent them from fully realizing their “potential”.
