What's wrong with the uninterrupted power supply (ups) alarm that keeps ringing? - Best uninterrupted power supply (ups)

UPS uninterruptible power supply alarm keeps ringing what is the problem? Generally, the UPS itself has an alarm function, including faults, input power interruption, etc. When the UPS power supply is abnormal, the alarm will send out a voice alarm message to notify the user of the current working status of the UPS in time. What causes the UPS uninterruptible power supply alarm to sound? In this article, the editor of Cunneng Electric will talk to you.

UPS uninterruptible power supply alarm keeps ringing what is the problem?

When using UPS uninterruptible power supply, different alarms will appear, and the meaning of each alarm is different. When an alarm occurs, the UPS locates the detailed cause immediately, informs the user and records it, so that the user can deal with it in time to avoid accidents.

There are many reasons why the UPS power alarm keeps ringing, but basically it means that the UPS power supply is abnormal. The reasons are as follows:

1. Disadvantages of UPS power system

Consider whether the UPS uninterruptible power supply system is short of power inside. If it is said that there is a power shortage inside, the alarm will automatically sound. In fact, the phenomenon of power shortage can be known by a simple inspection. Charge in time, do not let the UPS be in a state of power shortage for a long time.

2. External power failure

In the process of use, if the external power supply is out of power, and the inside is in a state of power loss, the alarm will keep ringing. At this time, because there is no power outside, there is no way to plug in the power supply. At this time, it is best to keep the state of shutdown for a period of time, and directly connect the UPS power supply to charge after the incoming call, so that the alarm will not sound.

3. Line failure

The circuits involved in UPS uninterruptible power supply are relatively complex, and there are a large number of circuit boards. If it is said that the circuit inside is faulty, it may be reminded by means of an alarm, then professional maintenance is required at this time, and the inside The faulty line is replaced or reconnected correctly, so that the alarm sound will stop by itself.

4. The voltage fluctuation range is too large

The voltage fluctuation range of the UPS power supply is too large, which has exceeded the normal voltage fluctuation range of the product, so at this time, out of self-protection, the alarm will sound continuously.

Even if you want to turn off the alarm, it is impossible, unless the voltage returns to the normal range, then you should suspend use at this time, and then check the cause of the excessive voltage fluctuation range, and avoid this in time. It happened again.

5. UPS power supply overload operation

The UPS power supply will also alarm when it is overloaded (there is not much overload, generally the UPS power supply will shut down for protection within the specified time), at this time it is not the UPS itself fault, as long as the overloaded equipment is stopped for a few times, the UPS power supply alarm will disappear. .

There are many reasons why the UPS's alarm keeps going off, but there may be others. These reasons are not easy for ordinary users to think of, and even if they are, they cannot be solved by themselves. It is time for the official after-sales personnel to solve this problem. After-sales personnel can bring some tools to check in order to find out specific questions.
