- Q: Is the UPS power supply a battery? Or is there a fundamental difference between the two?
- UPS power supply is the power, the battery is a battery, the difference between the two great UPS power supply is to the important equipment in the usual stable input of the electricity, play a regulator role, so that equipment in a stable power environment to run. In the case of abnormal electricity to provide a delay time And the battery is a kind of energy savings things, Of course, UPS to provide customers with the delay is the need to use the battery to provide electricity. Upstairs 2 do not know do not mess up, mislead Landlord is trying to buy a UPS?
- Q: UPS means Uninterruptible Power System uninterruptible power supply mean, UPD power supply? Please enlighten me.
- I think you are misspelled, not UPD is the PDU. PDU = Power distribution unit (can be understood as the machine room wiring board)
- Q: What is the difference between UPS and on-line?
- For the on-line UPS power supply, under normal circumstances, with or without electricity, it is by the UPS power inverter load the power supply, so to avoid all by the utility power grid voltage fluctuations and interference brought about influences. Because the on-line UPS power supply can achieve the load of the frequency, power supply, and in the electricity from the mains switch to the battery power supply, the conversion time is zero. Truly to provide users with high-quality voltage regulator, stable frequency of pure sine wave power supply, in order to meet the needs of the network system to provide power protection. Backup power: the normal power supply in the mains, the mains through the AC bypass channel and then directly through the transfer switch to the power supply, not through the UPS power supply. The inverter in the machine is in the working state, when the UPS power supply is essentially equivalent to a general performance of the mains regulator. In addition to the amplitude of the utility voltage amplitude has improved, the voltage instability, waveform distortion and interference from the grid intrusion and other adverse effects are basically no improvement. Only when the mains power supply is interrupted or below 170V, the battery is only the UPS inverter power supply, and to provide the load regulator, stable square wave AC power. It can be seen from the power supply principle and the steady frequency on-line UPS power supply quality is better than the backup UPS power supply. Because it can be achieved in addition to the load frequency, power supply, and in the electricity from the mains power to the battery power supply, the conversion time is zero.
- Q: 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.
- Q: Uninterruptible power supply UPS advantages
- Figure 1 is a typical UPS block diagram. Of course, UPS's uninterrupted power supply time is not infinite, this time is subject to the battery itself to store the size of energy. If the AC power outage occurs, then the UPS battery power in the valuable time, you need to do is to quickly restore the AC, such as the use of standby AC circuit, enable the oil generator, it is not, we can only save the emergency, save the fruits of labor, wait AC power to normal and then continue.
- Q: Brother for the first time to play ups would like to ask about this connection is wrong. I am connected to the uninterrupted power supply on the spark, what is the problem ah?
- Pay attention to the operation do not short-circuit, large capacity battery discharge capacity is very strong, short-circuit can be red instant screwdriver.
- Q: Uninterrupted power ups battery and electric car battery What is the difference, can replace
- Can not, the principle is not the same, UPS power supply is continuous power supply, and the electric car is intermittent, so not the same, but can be used, but the effect is not very good, thank you
- Q: It is expected that the power of the load equipment (computing server + ancillary equipment) is about 9KW, working for two hours in the event of power failure How much battery is used? How many pieces are right? What is the reason for the calculation?
- Recommended cost-effective one: Mountain ARRAY-MP-15KVA, +20 12V100AH maintenance-free battery, A20 cabinet, can meet the power at 9KW, power delay work for two hours. And the load is about 70%, the UPS run the best. Product power: 12KW (kW) Voltage input and output: single in single out External battery voltage: 240V (DC) single block number: 20 blocks Weight: 5 kg (kg) Size: 436 * 775 * 443 MM Application environment: small room Simple calculation: (100 * 20 * 12 * 0.8) /9000=2.13H (hours)
- Q: UPS concept and role? (The more the better) Thank you
- 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, the backup UPS on the load protection of the worst, online interactive slightly superior, on-line type can almost 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.
- Q: The server is IBM X3610 power is 600W should choose the kind of UPS power supply is better.As long as the sudden power failure to ensure normal shutdown on the line.
- If the mains voltage stability, then, do not have a voltage regulator with the UPS power supply, you can buy Hills TG1000, to bring the regulator can buy Hills K1000-Pro or MT1000-Pro
