After using UPS500A, the voltage is still unstable

If you use a voltage regulator and UPS can not solve the problem, then you should see whether the stable power provided by these two things can meet your load needs, if your load demand is too large, then there is no way, you can only change the voltage regulator and UPS with higher power, and whether the power supply voltage is too low, exceeding the limit of the stable work of the voltage regulator and UPS, you didn't say what exactly is used, but I saw that you always jump when you play, and you may use a computer, which should be enough as an ordinary UPS, 1First of all, check whether the battery capacity of your UPS is enough, and whether the power supply voltage is too low when in use, resulting in the battery not being able to have enough power for the computer to run;

2. If it is an empty open old jump, there may be a problem with the quality of the empty opening or it has been aged and damaged.

3. If it still doesn't work, it is recommended to complain to the local power company and call 95598 .......

I think you should jump when you're using the computer--- probably the machine is getting back up or simply shutting down.

Have you been looking at your computer for a long time?

If yes, just change the power supply and try it.

Two things have been added to the mains because it should have improved.

The voltage regulator chooses to slide well, and the runout is not good.

UPS Rings:

A: There is no mains power, and the distance between the two drops will be longer.

b: The battery is out of power, and the sound gap between two drops is short.

C: The battery is completely out of power, and the dripping sound is long.

Electrifying people. If the chassis is electrified, it means that the zero live wire is not connected correctly, or the ground wire is not connected, the general chassis to the ground and the voltage is not allowed to exceed the uninterruptible power supply, there are many types, if it is a special industry UPS, the power output is within the personal safety voltage, the output will not be electrified, the general UPS output is 110-230V voltage, which is fatal to the human body.

UPS Chinese for "uninterruptible power supply". It is a kind of energy storage device, with rectifier and inverter as the main components, to provide constant voltage and constant frequency uninterruptible power supply for monitoring systems, automation instruments, remote communication systems and other equipment in the substation.

The main role of the UPS system is twofold:

1) As an AC power supply for important equipment, it prevents the sudden power failure of the mains power from affecting the normal operation and causing damage to the equipment;

2) Eliminate "power pollution" such as power surges, instantaneous high and low voltages, wire noise, and frequency shifts in the mains, improve power quality, and provide high-quality power for computers, etc.

If your UPS is good, there are two possibilities for self-discharge:

1. The AC connection of UPS is not good, the plug is loose, and the mains power cannot be input normally.

2. The mains voltage is lower or higher than the voltage that UPS can accept, household UPS is generally a backup type, and the input voltage is mostly about 155-268V (of course, there are a few brands of UPS that may have a wider input voltage range), when the mains is lower than 155 or high 268, UPS will identify as abnormal voltage and cut off the mains input, so it will cause UPS to switch to battery mode self-discharge.

It may be caused by poor contact of the power socket of the UPS, check the power socket of the UPS, the UPS can be used under the regulated power supply.

There may also be quality issues.

Have you checked if the UPS mains has gone in?

The maximum output current of 500kva UPS according to power factor is about 606A 175 606=29%.Around; If the load is calculated according to the power factor, it is about 33%.But the power factor of large UPS is both.

The maximum output current of 120kVA UPS is about 182AA phase B phase 16 182= C phase

If the load of large-capacity UPS is too small, the displayed current and load will have a large deviation. It is still subject to the actual measurement data on site.

The battery life is 3-5 years, and the longer the battery is used, the lower the electronic activity in the battery, and the lower the battery efficiency.

Because the use time is too long or the maintenance is not good enough, at this stage, the inverter part of the UPS may be aging and the inverter output factor is too low, and the output voltage is too low, so the voltage is unstable or power failure. (more likely).

Aging of electronic components in STS static transfer switches.

If you are sure that your UPS has been turned on, it is very certain that the battery in the UPS is not working, and it is time to change it.

Big brother,It's been a few years since 07.。。 Do you think you should change it?
