+ Uninterruptible power supply system ups FAQ +
Q: What is an uninterruptible power supply system (UPS )?
A: The English name of the uninterruptible power supply system is uninterruptible power supply ". (So this ups is not faster than the express ups !). Therefore, the uninterrupted power supply system is literally a device that can provide power immediately when the power supply is interrupted to maintain normal computer operation.
Q: Why do I need an uninterruptible power supply system (UPS )?
A: unstable power quality can affect the normal operation of computers. In the constant power system, not only can the power supply be provided immediately when the power supply is interrupted, it can also regulate the power supply with poor quality, filter out noise, prevent lightning strikes, and other functions to provide stable and pure power supply for users. Therefore, having a power-on system is just as having insurance for computer equipment, and having it ready.
Q: What types of UPS are available?
A: There are roughly three types of UPS: off line, on line, and line interactive ).
Q: What is a backup uninterruptible power supply system (off-line ups )?
A: You can refer to the block chart of the standby system to directly supply power to the load using a path (also known as bypass) next to the mains supply. Battery power is provided only when power is unavailable. The inverter is converted to an AC power supply to provide load power.
Features:
1. When the mains supply is normal, the UPS can directly output the power to the load without processing the mains supply, and has poor attenuation capabilities for the mains noise and burst waves.
2. It has a conversion time with the lowest protection.
3. Simple structure and small size? Light Weight? Easy to control and low cost features.

Q: What is an on-line ups )?
A: The on-line ups is usually output to the load by the inverter. Only when the UPS is faulty, overloaded, or overheated will it be converted to a bypass output to the load.
Features:
1. the power output to the load is processed by UPS, with the highest output power quality
2. No conversion time
3. Complicated structure and high cost
4. The highest protection capability, the best for the municipal electrical noise and burst Attenuation

Q: What is an online interactive uninterrupted power supply system (line-Interactive UPS )?
A: The Online Interactive UPS is usually output to the load by the bypass transformer, And the inverter is used as the charger at this time. When the power is down, the inverter converts the battery energy to the AC power output to the load.
Features:
1. Two-way Converter Design, UPS battery recovery time is short
2. conversion time
3. complicated control structure and high cost
4. the protection function is between the on-line and the standby ups. It has poor attenuation capability for mains noise and sudden fluctuations.
Q: How can I choose an uninterruptible power supply system (UPS )?
A: 1. Understand the applicable status of various architecture UPS
2. Consideration of power quality requirements
3. Understand the required UPS capacity and consider the total capacity for future device expansion.
4. Select a reputable brand and manufacturer
5. select an appropriate ups type based on your requirements
Q: What should I pay attention to when purchasing an uninterruptible power supply system (UPS?
A: 1. The most important thing about the quality of UPS is its excellent stability and availability. *
2. Timely sales and maintenance services are available in various regions
3. Excellent R & D engineers and innovative product development capabilities
4. high efficiency and low noise
5. providers with better reputation and sound financial structure
6. The product has been certified by foreign inspection institutions, such as TUV, UL, and CSA.
7. The factory has passed certification by foreign inspection agencies, such as ISO9001 and ISO9002
Q: I rarely have power outages in my place. Do I need an uninterruptible power supply system (UPS?
A: According to statistics, power outages only occupy a small part of power problems that are hard to detect. For example, high voltage, low voltage, and sudden bursts are the major problems of power supply. The purpose of the UPS design is to provide comprehensive power protection for customers' extremely important loads. Including voltage regulation, protection against burst damage, prevention of high-frequency interference, prevention of any type of power supply interruption or floating, and can provide unlimited long-delay power supply.
Q: How long does the uninterruptible power supply system (UPS) Take for power supply?
The maximum purpose of UPS is to provide an appropriate backup power for the load device when the power supply is abnormal. Therefore, the ups backup time should be sufficient for the user to have enough response time in the face of Power exceptions. Generally, the backup time of 5-10 minutes is enough. In addition, if you need a longer backup time, you can consider purchasing a UPS model (that is, long-delay ups) that can be attached to the battery box ).
Q: How can I calculate the capacity of an uninterruptible power supply system (UPS?
A: At present, most of the uninterruptible power supply systems sold in the market use va as the unit of capacity. V is the voltage, A is the current, and V * A is equal to the power, that is, the capacity of the uninterruptible power supply system. For example, if the output voltage of an uninterruptible power supply system of megava is 110 V, the maximum current available for its products is 3.86. exceeding this current indicates overload ). Another method for expressing power is W, W, and VA. The difference between the two is the power factor. There is no standard for the number of power factors, generally between 0.6 and 0.8. If it is 0.5, the product is not well designed. This number should be considered when purchasing a power-on system.
Q: How can I extend the duration of the uninterruptible power supply system (UPS?
A: There are two ways to extend the duration of the uninterrupted power supply system:
Additional battery box: the advantage is to mount the array battery box according to the required power supply time, but note that this method will increase the battery charging time, and also increase the maintenance equipment, product volume and cost, therefore, it is necessary to evaluate it.
Choose an uninterrupted power supply system with a large capacity: This method not only reduces maintenance costs, but also can be operated immediately if the load equipment is expanded.
