With the continuous development of modern society, people's life and production needs continue to improve, "electricity" is an indispensable thing for people, due to excessive power supply pressure, or unstable current, in order to ensure uninterrupted power, more and more enterprises and individuals choose uninterruptible power supply, has become an indispensable equipment for our work and life, so what issues should be considered when choosing UPS power supply for the first time?
1. Stability
Because UPS plays a role in power supply, its own stability is more important, so when users buy UPS products, they must first consider the quality of UPS products, the quality of the product is the first priority for users to choose products, and the quality can determine which brand of products to choose.
2. Backup time
From an academic point of view, UPS is to continue to supply power to users after a power outage, which is only one of its functions, and the second function is to ensure that users can have a pure power supply.
3. Determine the type of UPS
According to the load pair output stability, switching time, and output waveform requirements, it is determined whether to choose online, online interactive, backup, sine wave and square wave types of UPS.
The output stability of the online UPS, the instantaneous response ability is stronger than the other two, and the adaptability to nonlinear loads is also strong, for some more precise equipment, the more important equipment should use online UPS, in some areas with a large range of mains power fluctuations, avoid the use of interactive and backup types, if you want to use generators with short delay UPS, it is recommended to use online UPS.
What if the UPS fails or stops working altogether? How do you know if there is power in the event of a power outage? Here are some tips to help.
✪1. Make sure the UPS is plugged in. If it can't be "turned on", check that it is connected to a power source and that the circuit breaker is not tripped.
✪2. Make sure that UPS is set to "On". UPS devices need to be "turned on" to operate. If you have just installed a brand new UPS system, you need to press the "On" button to make the base work. It is not enough to plug the UPS into a wall outlet, it will not start working until the "ON" button is pressed, regardless of whether the LCD screen is on or not.
✪ 3. Check the fuse of the UPS. If you did everything right and checked all the wiring, but the UPS still doesn't "turn on", it could be a blown fuse. Find a professional to check and replace.
✪4. Check the wiring. UPS devices should not use batteries when mains power is available! If you notice that it is using batteries when they shouldn't, make sure to power the UPS and check the circuit breaker. If the device is "on" and everything is working properly with your power supply, contact the manufacturer's technical support.
✪5. Check the battery. The UPS should be able to provide backup power if needed, and the battery may wear out with frequent use, even if the "Replace Battery" status has not yet appeared. Use the UPS's "self-test" feature on a fully charged battery to ensure it is working properly. If the test fails, the "Replace Battery" indicator will be displayed.
✪6. Adjust and balance the load appropriately. Make sure the UPS is sized for the load and can handle it. If there is a three-phase UPS system, load balancing is important to avoid THD (or total harmonic distortion) issues. Insufficient use can lead to wasted energy.
✪7. Connect only the most important devices. If you notice that there are a lot of devices connected to the UPS, but not all of them are critical during a power outage, unplug it. This will extend the time the UPS can power critical equipment and computers.
✪8. Get professional advice and maintenance services. Industrial-scale UPS requires careful management. If the UPS power supply system is huge, it needs to be inspected regularly by professionals. Especially if there is a problem with the wiring, this is not a DIY project.
