Huabao Golden Warrior ups power supply

Nowadays, UPS power supply does not only show its talents when the power is cut off, and more often the power supply is uninterrupted. The UPS power supply itself often has some failures. If the UPS power supply fails, it will not be able to provide protection for the load. Here are some reasons for the premature failure of UPS power supply.

The following five major factors may cause the UPS power supply to fail prematurely!

1. Improper storage of UPS power supply

Even if the UPS power supply is not used, its life will begin to decrease. That's because the lead-acid UPS power supply will automatically release a small amount of energy.

In order to extend the storage life of the UPS power supply, it is recommended that you charge it every three to four months. If you don't do this, you may see permanent capacity loss in just six months. You can also extend the service life of unused UPS power supplies at 50°F (10°C) or lower.

2. The ambient temperature is too high

The rated capacity of each UPS power supply is based on an ambient temperature of 25°C (77°F). Any changes (especially temperature rise) will affect performance and service life. Generally, for every 15°F increase in the recommended ambient temperature, the life expectancy of the UPS power supply will be reduced by 50%.

For UPS power supply, the working environment should be the same as that of the computer. The temperature should be controlled above 5°C and below 25°C; the relative humidity should be controlled below 50%, and the upper and lower ranges should not exceed 10%. Routine maintenance inspections can help spot hot spots and verify ventilation.

3. Excessive circulation

After the UPS runs on the UPS power supply during a power failure, the UPS power supply will be charged for future use, which is called a discharge cycle. After the UPS power supply is installed, the UPS power supply will reach 100% of its rated capacity. However, each discharge and subsequent charge will slightly reduce the capacity of the UPS power supply.

4. Incorrect floating voltage

Each UPS power supply manufacturer will specify the charging voltage range for its own UPS power supply design. If the UPS power supply continues to charge outside of these parameters, it may cause serious damage. Insufficient charging or low voltage can cause sulfate crystals to form on the UPS power board.

Over time, these crystals will harden and reduce the usable capacity of the UPS power supply. Excessive float voltage will cause excessive hydrogen and oxygen, and may cause internal drying. Once accelerated, internal drying will cause thermal runaway, leading to malfunctions and even fires.

5. Incorrect use of UPS power supply

UPS power supplies are dedicated to UPS, just as other UPS power supplies are dedicated to their respective appliances. Any power supply has its unique set of rules and regulations and methods during use, for all of us to use. The service life of the UPS uninterruptible power supply system is closely related to the usage, so it is necessary to pay attention to the method and maintenance in normal use.

The maintenance and use of UPS power supply are inseparable. There should be scientific use methods and correct maintenance methods to achieve high UPS utilization.

1. When the uninterruptible power supply UPS is maintained, it must be performed while shutting down to prevent internal high voltage from ionizing and causing charged particles to trigger IGBT and cause equipment failure.

2. If the UPS power supply with maintenance bypass can be transferred to the maintenance bypass, the internal power is still live during maintenance.

3. The UPS power supply must be self-discharged before maintenance.

4. Use a vacuum blower as a maintenance tool, and never use a damp cloth.

When the UPS battery system fails, you should first find out the cause, and distinguish whether it is the load or the UPS power system; whether it is the host or the battery pack.

When performing UPS power supply maintenance, be sure to pay attention to safety. When handling power equipment, even a small operating error may cause serious injury. Therefore, when dealing with UPS power supply, the Golden Samurai UPS power supply manufacturer reminds that safety rules should be followed: including complying with the equipment manufacturer’s recommendations, paying attention to the special details of the facility and standard safety guidelines.

Note: When designing UPS power supplies, each manufacturer will have a little bit of small changes or changes in location functions. It does not mean that all UPSs have the same problem and the repair and solution methods are the same. You cannot use the UPS experience of one manufacturer. On another UPS product.

In the daily process of UPS power supply maintenance, we can find that many UPS failure phenomena are caused by factors such as battery, mains power, use environment and use method, and a considerable part of UPS itself has not failed. If you can find out these factors and determine that the fault is not caused by the UPS, the problem can be solved more quickly.
