    What are the Protection Functions of UPS Power Supply?

    UPS uninterruptible power supply is a type of uninterruptible power supply that includes energy storage equipment. So what are the protection functions of UPS uninterruptible power supply? When the utility grid is suddenly cut off, the UPS will immediately convert the DC power of the UPS power supply battery into AC current and continue to deliver power to the load to prevent troubles and losses caused by power cuts.

    What are the Causes of UPS Inverter out of Sync?

    The ups inverts the mains input power. When the mains input power is abnormal, the ups inverts the mains input power based on the ups inverter frequency. The frequency at which the generator generates electricity is very unstable and may be outside the frequency range at which the ups inverter tracks mains power. The ups inverter is not synchronized. The ups inverter is not synchronized, which also results in consequences. The ups inverter is not working. First of all, we need to know what are the reasons for the ups inverter out of sync?

    How Long Will the UPS Battery Last?

    In fact, many UPS now also use lithium batteries, which can be integrated into standard racks. However, due to the limitation of volume, the battery capacity will not be very large. Correspondingly, the result is that the backup time is not long enough, and the rated backup time is maybe five minutes. Make sure that the server can be saved and shut down normally, or wait until the engine is powered on. But by 2022, in the current mainstream application solutions (95%+), UPS is still used in conjunction with lead-acid batteries. ATO uninterruptible power supply batteries are lead-acid batteries.

    ATO UPS is the abbreviation of the uninterrupted English name, which appeared with the birth of the computer and is one of the commonly used peripheral devices of the computer. Actually. UPS is a kind of uninterruptible power supply with constant voltage and constant capacity with an energy storage device and inverter as the main component. Now that UPS is becoming more and more popular, let's take a look at the main protection functions of uninterruptible power supplies?

    Can a UPS Power Supply Run a Refrigerator?

    Can a UPS run a refrigerator? the answer is negative. UPS is strictly prohibited to connect the inductive load, it will overload. The refrigerator is designed with a wide voltage, no voltage regulator and other equipment are needed, a UPS of about 1000W is enough. The refrigerator works continuously for 5 hours, the battery capacity needs 12V&180Ah, plus the no-load power consumption, the conversion efficiency is estimated to be 80%, which can guarantee the refrigerator power supply for 8~10 hours.

    Is the UPS Battery Backup Noisy?

    UPS is an uninterruptible power supply with an energy storage device. It is mainly used to provide an uninterrupted power supply to some devices that require high power stability. What is the reason for the loud noise of the UPS? How to deal with it? Fans, inductors, and transformers will make noises when the UPS is working. When the UPS is working, generally a slow beep is a small fault (which can be automatically recovered), a rapid beep is a major fault (recoverable), and a long beep is a major fault. Let us learn together what are the reasons for the loud noise of UPS?

    How Many Watts Does a UPS Use?

    How much power does the UPS have? How to choose UPS power? The sum of squares of UPS active power and reactive power is equal to the square of apparent power. Generally, the active power is about 60%-70% of the apparent power. Confirm the power of the equipment loaded by our UPS, and then you can confirm the power of the UPS. In general, ATO.com recommends that the load power accounts for 30% to 80% of the UPS power.

    UPS (Uninterruptible Power Supply) Troubleshooting

    When there is mains power, the UPS output is normal, but when there is no mains power, the buzzer beeps for a long time and there is no output. Fault analysis: It is judged from the phenomenon that the battery and inverter are partially faulty, and can be checked according to the following procedures.

    What are the Types of UPS Power Supply?

    The uninterruptible power supply is a very important power supply device in our daily life and work, and it can even be said to be ubiquitous. So which type do we usually see? What are the differences between these different types of ups in their work? Let's take a look. Uninterruptible power supplies are usually divided into three types, namely offline, online, and online interactive. These three types of uninterruptible power supplies are very common in work and production.

    What is a UPS?

    UPS is a device that contains energy storage. It is a constant voltage and constant frequency uninterruptible power supply with an inverter as the main component, which can solve the problems of power failure, low voltage, high voltage, surge, noise and so on of the existing power, and make the computer system run more safely and reliably. Now ATO UPS has been widely used in computers, transportation, banking, securities, communication, medical, home, industrial control, etc.

    What is UPS Battery Backup Used For?

    UPS, also known as an uninterruptible power supply, is a constant voltage and constant frequency uninterruptible power supply with the energy storage device and inverter as the main component. It mainly provides uninterrupted power supply to a single computer, computer network system or other power electronic equipment. When the mains input is normal, the UPS will stabilize the mains and supply it to the load. At this time, the UPS is an AC mains voltage stabilizer, and it also charges the battery inside the machine. When the mains power is interrupted (accidental power failure), the UPS will immediately supply the 220V AC power to the load by inverting the power of the battery in the machine, so that the load can maintain normal operation and protect the software and hardware of the load from damage.

    How Long Does an Uninterruptible Power Supply Last?

    How long can UPS equipment supply power? UPS manufacturers have industrial UPS power supplies with 10 minutes, 30 minutes and other types. Is the UPS time longer the better? In fact, it is better to control the UPS time within 8 hours. Why is this?

    Uninterruptible power supply (UPS), how it works?

    UPS power system consists of 4 parts: rectification, energy storage, transformation and on-off control. UPS realizes the function of voltage stabilization with rectifier, which is generally a silicon-controlled rectifier (SCR) or high-frequency switching rectifier. The rectifier controls the output amplitude according to the change of external power supply; when the external power supply changes (the change should meet the system requirements), it outputs a rectified voltage whose amplitude keeps unchanged. Purification function of UPS is completed by the energy storage battery. As the rectifier cannot eliminate instantaneous pulse interference, the rectified voltage still has interference pulse. Energy storage battery can not only store DC power, but also plays a role of large-capacity capacitor for the rectifier, its equivalent capacitance is proportional to the capacity of energy storage battery. As the voltage at both ends of the capacitor can’t change suddenly, the pulse interference is eliminated due to the smoothness property of capacitor for pulses, thus realizing the purification, as well as the shielding against interference. Converter guarantees a stable frequency of uninterruptible power supply. Frequency stability is determined by the stability of the converter's oscillation frequency. To facilitate daily operation and maintenance of UPS power system, an operating switch, automatic bypass switch after fault self-checking, overhaul bypass switch are designed in this system.

    Uninterruptible Power Supply (UPS) Troubleshooting FAQ

    There's no display on the panel after the UPS starts, UPS doesn't work?
    Fault analysis: the fault may lie in power input, battery and power detection, battery voltage test circuit:

    1. Check if the power input fuse is burned out.
    2. If the fuse works normally, check whether the battery fuse is burned out, because some uninterruptible power supply may close all outputs and display when it can't detect a voltage.
    3. If the battery fuse is complete, please check if the power detection circuit works normally. If it doesn't work normally while UPS can't start without power supply, UPS will also close all outputs and display.
    4. If the power detection circuit works normally, please check if the battery voltage test circuit is normal.
