Precautions for uninterruptible power supply during discharge

Today, I bring to my friends the knowledge about UPS uninterruptible power supply (hereinafter referred to as UPS) maintenance.

   UPS in daily use, only a regular basis to extend the life of the UPS UPS discharge can generallyspeaking, UPS power supply battery charge and discharge at least once every three months, how can discharge the UPS allowed to dothe greatest strength How about it? Now, let's talk to you about the precautions during the charging and discharging process.

   When discharging the UPS uninterruptible power supply , please be sure to adhere to the following precautions

1. Before you discharge, you must first understand how long the UPS power supply can be backed up. In this way, when the discharge is made, you will be prepared to prevent the discharge from reaching the backup time. .

2. If you can see the UPS battery, first visually inspect the battery for obvious deformation and leakage.

3. If the UPS uninterruptible power supply itself has an automatic discharge function to set the time, it is recommended that the UPS uninterruptible power supply first perform a discharge itself, so that it can initially determine whether the battery has a discharge function.

4. During the artificial discharge, please pay attention to the drop of the battery voltage of the UPS at any time, so as to access the mains input at any time.

5. It is not necessary to completely discharge the capacity of the battery for the first time to discharge the UPS . Here, it is only OK to put it at 2/3 of the rated capacity . The discharge only needs to activate the battery. Extend the life of ups batteries.

6, if the power of the UPS power supply , the rectifier and the bypass input switch generally independent design, it is recommended rectifier OFF switch can, without user mains input OFF switch to prevent the battery discharge occurs outside the case, can immediately UPS i.e. Go to bypass mode to work.
