　　Author ：Iflowpower – Portable Power Station Supplier

To provide a backup power supply to your notebook, you first want to understand the voltage and power of your laptop, then use the battery. UPS (UninterruptiblePowersystem), the uninterruptible power supply, is an uninterruptible power supply containing the constant voltage constant frequency of the main components in the inverter. You can buy a UPS of 500W, equipped with a battery of 12V40AH, usually charge the battery when there is electricity time, when the notebook can directly use the 220V inverter power supply provided by the UPS, two computers are not available for two hours questionable.

UPS (UninterruptiblePowersystem / UninterruptiblePowersupply), is uninterruptible, composed of battery packs, inverters, and other circuitry, is to connect the battery (mostly lead-acid-free maintenance storage) to the host, by a modular circuit such as host inverter DC electrical conversion into a commercial system. Bedroom dedicated UPS refers to the use of large-capacity battery packs, which can be fully charged while charging, full of electricity, 3 to 12 hours or longer. Mainly used to solve some inconvenience caused by sudden power outages of the bedroom.

The dormitory-specific UPS is when the city is powered on, the electrical supply load in the battery is reversed to the standard voltage supply load, ensuring the supply of green stable and sustained power supply, will not let the computer used in use because of sudden power outages future and storage And lost important documents [2]. UPS is the abbreviation of UninterruptiblePowersupply, that is, the UPS power supply, or the UPS uninterruptible power supply. It is a power supply device containing the energy storage device, inverters, the constant voltage constant frequencies, is one of the indispensable peripherals that cannot be powered off, and its role is In the case where the external interrupt is powered, it is supplied to the computer and other devices to avoid affecting the interruption of communication, the loss of important data and the damage of hardware.

It has been widely used in precision instruments, medical equipment, communication systems, safety monitoring, network systems, automatic control production lines, etc. Important equipment. The UPS power is three types: online online UPS (on-lineups) operation mode is "quarantine and electricity equipment is isolated, the main electricity does not directly supply power to the electric equipment", but to the UPS is converted Become a direct current, then divided into two ways, all the way to charge the battery, another way to turn back the AC electricity, power supply to the electric equipment, the city power supply quality is unstable or power outage, the battery is turned from charging to power supply, until the city electricity recovery is normal Revert to charge, "The entire process of using electricity is involved in the whole process".

It is the advantage that the output of the output is sine wave, and the pure net is no negative, which is not affected by the instability of the mains, which can be powered to "inductive load", such as a fan, as long as the UPS output power is sufficient. Under the topic, you can supply it to any equipment that uses a city. Rear-standing rear-pre-pre-preparative working principle is also known as non-line uninterrupted power supply (OFF-lineups), it is just the "reserve" nature UPS, and the direct supply of electricity supplied by electricity is also battery charging (NormalMode).

The city power supply quality is unstable or power outage. The city's circuit will automatically cut off. The battery's DC electricity will be converted to the tasion of the transfer of electricity, until the city's electricity is normal, "UPS only has the power failure in the city Interventional power supply ", but the AC electricity from DC-converted is square wave, which is limited to power supply to capacitive load, such as computers and monitors.

Online Interlaced Online Interactive Working Principle Online Interlaced is also called online interactive or online-interactiveups, the basic mode of operation is, the difference is in the online interlaced although there is no online The whole process is involved in power supply, but at any time is monitoring the power supply of the city, itself has a boost and decompression compensation circuit. When the power supply status of the market is not ideal, instant correction, reduce unnecessary "Batterymode" switch, extend the battery life. Most regions and big cities in my country are urged with power supply tightness.

The quality of power supply is guaranteed. The city electricity cannot provide the clean and stable power supply required for sensitive electronic equipment, causing the user to eventually be full of the health and safe operation of the equipment, and the real role is that the following aspects: 1) Power-saving protection: AC input interrupt time UPS The power supply immediately converts the battery DC power supply into the traffic flow continues. Retrieval power supply time is determined by battery capacity, load size, etc.

2) High and low voltage protection: UPS internal regulator (AVR) will make appropriate adjustments, so that the voltage of the UPS output is maintained in the range of use, if the voltage is too low or too high Using the range, UPS converts the battery DC power supply into the traffic flow to continue power supply to protect user equipment. 3) Waveform distortion processing: Since power is transmitted to the client via the output line, the use of various machine devices often causes distortion of the main market voltage waveform, as the waveform distortion will generate harmonic interference equipment, and the power system transformer temperature Elevation, generally required distortion rate <5%, general UPS design distortion rate <3%. 4) Frequency stability: The market is divided into two types of 50Hz / 60Hz.

The so-called frequency is the cycle of each second. 50Hz is 50 weeks per second. China is 50Hz.

When the generator is running, the rotational speed of the rotational speed caused by the transformed power frequency, and the power converted by the UPS power supply provides a stable frequency. 5) Voltage stability: The market electrical pressure is easily affected by the quality of the power delivery line. The user voltage higher than the substantial electrical circuit is higher than about 240 to 260V.

The user voltage from which the power-away power is low is about 180 ~ 200V, voltage Too high or too low will cause user equipment to shorten the life, when it is severe, use online UPS to provide stable power supply voltage, extend equipment life and protection equipment. 6) Inhibit common mode noise: common mode noise generation between the fire / ground wire and the neutral line. 7) Inhibition of differential mode noise: differential mode noise is between the fire line and the neutral line.

8) Breakthrough protection: General UPS will add a surge in surge absorber or tip discharge to protect user equipment. 9) Instantaneous Response Protection: When the market is interfered, it sometimes causes a voltage protrusions or inactive or instantaneous interruption. Use the online UPS to provide a stable voltage, so that the voltage fluctuates within a smaller range, can extend the equipment life and protection equipment.

10) Monitoring power: Smart communication interface and monitoring software with UPS power supply can display real-time status information such as UPS voltage, frequency, load, battery, temperature, and display the countdown shutdown after the market is interrupted, and before the battery is exhausted Safety automatic shutdown system and UPS power supply. 1. Since the power grid has at least nine problems such as power off, lightning strike spike, surge, frequency shock, voltage mutation, voltage fluctuation, frequency drift, voltage drop, pulse interference, etc.

, therefore, from the perspective of improving power quality, it gives yourself. One UPS is very necessary. 2.

A ordinary computer, which uses software value such as data files after three months, has exceeded hardware value, so it is also very necessary to prevent data loss. Stability UPS power is a guarantee, so its own stability is more important. Therefore, when elect the UPS power supply, you must first consider the quality of the UPS product.

The quality of the product is the first essentible of the user who chooses the product. You can decide what brand you will choose. Backup time backup time is a more than one indicator when purchasing UPS power products.

From an academic perspective, the UPS continues to power the user after power failure. First of all this is a physics, the power outage is only one of its functions, and the function is guaranteed to have a clean power supply to protect the user's equipment. The determination type is determined based on the load pair output stability, switching time, and output waveform requirements are the selected online, online interactive, rear-pre-collapse, and sine wave, square wave and other types of UPS.

The size of the battery UPS power battery capacity is reflected by the indicator of "safe number (AH)", and its meaning is discharged according to the specified current. The battery of the same voltage is large. The number of times is large; the same adjustable battery, the voltage is high, usually the capacity of the battery is commonly represented by the number of voltages, such as 12V / 17AH, 12V / 24AH, 12V / 65AH, 12V / 100AH.

The battery is an important part of UPS, accounting for a large value, and the quality of its quality is directly related to the normal use of UPS, so it should be carefully selected to have quality assurance.
