Portable UPS Power Supply Precautions
- Apr 18, 2018 -

Portable UPS power supply as an energy storage device for an uninterruptible power supply system plays an extremely important role in ups. When utility power is interrupted, the portable UPS power supply will continue to supply power to the load by relying on the energy stored in the portable UPS power supply. At present, portable UPS power supplies are widely used maintenance-free lead-acid portable UPS power supply, its price is relatively expensive, generally accounts for about 1/4 of the cost of the entire ups system. This shows that how to ensure the normal operation of portable UPS power supply and extend its service life as far as possible is no small matter.

Portable UPS power supply occupies a very important position in the UPS, it was said that portable UPS power supply is "the heart of UPS", we can not see too much. Because the portable UPS power supply occupies a considerable proportion of the production cost of the UPS, in actual use, the proportion of the UPS that cannot work due to the portable UPS power supply problem is greater than its proportion in the production cost. In actual maintenance, people do not pay attention to it, and the phenomenon of neglecting it is even more serious. Some units spent nine years and two powers before applying for several UPS units, but they were reluctant to use them. It took one year at the warehouse to leave them unattended. Some units of standby UPS, long-term backup, even the charger output of the portable UPS power supply is stopped, and the portable UPS power supply is not charged once in half a year. In one year, two years, and even four years and five years, the terminal voltage of a portable UPS power supply is not checked. However, as long as the portable UPS power is treated with care, the portable UPS power supply will double back to people. Because it will not only provide you with enough capacity to ensure that electricity will be maintained for a long enough period of time after the electricity outage, but it will also extend the service life and serve you more.

Portable UPS power supply should generally pay attention to the following issues:

1. It is strictly forbidden to over discharge the portable UPS power supply, such as discharging the battery to automatic shutdown, artificially lowering the minimum protection value of the portable UPS power supply, etc., which may cause the battery to be over-discharged.

2. For areas with frequent power outages and frequent discharge of portable UPS power supply, take measures to ensure that the portable UPS power supply has enough charging time after each discharge to prevent the portable UPS power supply from being undercharged for a long time.

3. For a UPS that rarely loses power, and portable UPS power is rarely discharged, it is necessary to cut off the mains power once every 2 to 3 months to allow the portable UPS to discharge power for a period of time to prevent the portable UPS power supply from “storage aging”.

4. Regularly check the terminal voltage and internal resistance of the portable UPS power supply, and discover the “backward” battery in time to perform individual processing.
