Shante MT500 UPS Issues

No, my friend, there are 2 possibilities: (1) your computer is too powerful, and (2) you are buying a counterfeit product.

Jianyi, turn off the computer, try not to bring the computer to see if it rings, no, I Jianyi you ** business there to change a svcups, the quality of the Shante UPS power supply is now much inferior to before. SVC V-500C V625 voltage regulator king is also OK, and the final commitment to stability is to customers.

MT500 can only tow 300W. Your maximum load is 450w+50w, about 500w

The tripping UPS at home can still drive, which means that your load is just over the rated 300W, so the UPS holds it up and makes a DIDI sound to warn you that the energy is not enough and it is going to shut down.

A loud snapping sound should be the sound of a relay jumping in and out. It stands to reason that if it is closed, it will be closed, and it should not be restarted. In addition to the reply of the mains.

Upstairs is right, the other possibility is that you bought a fake or the quality of the UPS itself.

However, it is not reasonable to recommend a voltage regulator upstairs. When there is a power outage, there is no point in stabilizing the voltage.

You try again according to my method, use this UPS with other loads that must be less than 300W, turn off the mains power to see if there is a problem with UPS as you said, if everything is normal, your UPS capacity is small, if there is still a crackling sound, then UPS is faulty.

It is suspected that it is an alarm sound, and it may be a problem with UPS parameter setting.

Go to the official website of Sandups to take a look.

Hit Shante 800** ask or find Shante maintenance station to repair it.

This is the UPS power supply (uninterruptible power supply protection power supply), which is used to continue to supply power for about 15 minutes (some large capacity can be provided up to 1 hour) when the power grid is cut off, and the user can save data and safely shut down the computer (or other electrical equipment).

The use of this UPS is very simple, plug it into the wall power supply, and then plug the power supply of the computer (or other electrical appliances that need uninterruptible power supply) into the socket of this UPS.

There is no such thing as booting, when plugged in, the UPS will automatically turn on. And the round button at the top, (in the power-on state) can be manually turned off (disconnected from the power) by pressing and holding it now, and then press it again to power it on again.

There is a set of rechargeable battery modules that can be replaced in UPS, and after a long time (about 3 5 years), the battery itself can not be recharged, and it cannot play the role of uninterrupted power supply protection, and this battery module needs to be replaced.

<> plug in the mains socket and press this button for about a second (the time should not be too short, it will not turn on; The time should not be too long, avoid turning it on and turning it off), you will hear the sound of booting, these lights will turn on again, and only one green light will be on after normal boot. Turn on the UPS first, and then turn on the load after the UPS is stable after it is powered on.

Shanteups working mode: mains mode, battery mode, bypass mode.

Mains mode: Mains input battery float charge.

Battery Mode: Mains power interrupts and the battery is discharged.

Bypass Mode: Mains input UPS is not powered on.

The description is too general, can't do it, brother, there is no model failure.

Battery-powered is not the mains power plugged in properly.

The actual wiring diagram is as follows, and there are two things to pay attention to:

1. When connecting the battery, you must pay attention to the insulation, do not cause a short circuit, although it is still within the safe voltage range after series merging, but the short circuit will damage the battery.

2. After completing the wiring work, be sure to check whether the polarity and the total output voltage are 36V, if not, it means that the connection is wrong.
