FAQ

3000W load with a large number of UPS uninterruptible power supply is appropriate, the backup time to 12 hours
General UPS load factor of 0.6-0.7 or so, the need to configure the 5KVA UPS was appropriate.   If the UPS is connected in series with 16 batteries, the rated voltage of the battery pack is 192V, the inverter battery discharge current is about 3000/192 / 0.85 = 18A, 0.85 is the inverter efficiency, 18 * 12 / 0.9 = 240Ah, 0.9 for the battery discharge efficiency. The actual configuration 120Ah * 16, 2 groups in parallel is enough.s
What does the UPS power supply mean? Thank you, the big god to help ah
Half of the meaning is not reached the rated power is called half load.s
The use and maintenance of uninterruptible power supplies
(4) on the host to break, break the insurance or burn the device failure, be sure to identify the cause and troubleshooting to be able to restart, or will occur the same failure. (5) When the battery is found in the voltage reverse polarity, pressure drop, pressure and acid mist leakage of the battery, the timely use of the appropriate method to restore and repair, can not be restored and repair to be replaced, but not different Capacity, different performance, different manufacturers of batteries together, or may have a negative impact on the entire group of batteries. On the life of the battery pack has been expired in time to replace, so as not to affect the host. UPS as a protective power supply, its performance parameters of great significance, should be the focus of our purchase considerations. The mains voltage input range is wide, indicating that the use of electricity is strong (to reduce the battery discharge). Output voltage, frequency range is small, it shows that the mains adjustment capacity, output stability. The waveform distortion rate is used to measure the stability of the output voltage waveform, while the voltage stability indicates the stability of the output voltage when the UPS is suddenly loaded from zero load to full load. As well as UPS efficiency, power factor, conversion time and so are important parameters that characterize UPS performance, determines the protection of the load and the utilization of electricity. The better the performance, the stronger the protection, in general, off-line UPS on the load protection of the worst, slightly interactive online, online type is almost able to solve all the common power problems. Of course, the cost increases with the performance of the increase. Therefore, users in the purchase of UPS, the load should be based on the degree of power requirements and the importance of different load, and select different types of UPS.s
Ups uninterruptible power supply back - up and on - line difference is what does anyone know?
Backup UPS is also known as non-online UPS   Backup UPS: usually in the battery charge state, in the event of an emergency switch to the working state of the inverter, the battery provided by the DC into a stable AC output, so the backup UPS is also known as off-line UPS. Backup UPS power supply advantages are: high efficiency, low noise, the price is relatively cheap, mainly applicable to major fluctuations in electricity, the power supply quality requirements are not high occasions, more suitable for home use. However, this UPS has a switching time problem and is therefore not suitable for use where critical power supplies can not be interrupted. But in fact this switch is very short, usually between 2 to 10 milliseconds, and the computer's own switching power supply in the power failure should be able to maintain about 10 milliseconds, so the personal computer system is generally not because of this switching time problem. Backup UPS can only continue to power a few minutes to tens of minutes, mainly to let you have time to back up data, and as soon as possible the end of the work, the price is low. For computer applications that are not too critical, such as personal home users, they can be equipped with a low-power backup UPS.s
10KVA UPS can take up the need for 6000 watts of power appliances?
10KVA UPS can take 6000 watts of electrical appliances. Depending on your power factor! In general, 10KVA high-frequency machine can take 7000W, frequency machine can take 8000W. But if you bring the electrical,s
What is ups power
When the mains input is normal, UPS will be the mains power supply to the load after use, this time the UPS is an AC power regulator, while it also charge to the battery; when the electricity interruption (accident power failure) , The UPS immediately to the battery DC power, through the inverter switching method to the load to continue to supply 220V AC, so that the load to maintain normal work and protect the load soft, the hardware is not damaged. UPS equipment is usually too high voltage or voltage can provide protection.s

What is the difference between UPS power supply and UPD power supply?
UPS is an uninterruptible power system (English), is able to provide a sustained, stable, uninterrupted power supply of important external equipment. In principle, UPS is a set of digital and analog circuits, automatic control inverter and maintenance-free storage devices in one of the power electronic equipment; Functionally speaking, UPS can be abnormal in the mains, the effective purification of electricity; can also be a sudden interruption in the city power for a certain period of time to the computer and other equipment power supply, so you can have plenty of time to cope with; From the use of information society, UPS is widely used in information collection, transmission, processing, storage to the application of all aspects, the importance of information applications with the increasing importance of increasing. UPS according to the working principle is divided into backup, online and online interactive three categories;s
