The Difference between UPS and AVR

The Difference between UPS and AVR

Does the regulator function the same as the UPS power supply?With more and more electric equipment in the market, voltage regulator and UPS power supply are widely used, many feel that they can replace each other.But there is a difference between the voltage regulator and the UPS power supply, and many people always mistakenly think that the voltage regulator is the UPS.The following from several aspects to introduce the voltage regulator and UPS power supply difference.

Does the regulator function the same as the UPS power supply?

UPS:

UPS power supply is divided into online UPS power supply and backup UPS power supply, the general home computer is equipped with a backup UPS power supply, it belongs to a backup power supply;Backup type is with the voltage regulator part, the use of relay shift voltage regulator, voltage regulator effect is very poor, can not be regarded as a regulator.

UPS power supply is the short of uninterruptible power supply, can be seen from the name it is actually a reserve power, when power outage, through summary storage battery power after inverter output ac current to the power supply equipment use, and usually the time interval from the host switch to standby power in less than 10 milliseconds, so power is almost not any effect on electrical equipment.

Voltage Stabilizer:

It is designed for power network voltage instability, mainly for the protection of back-end equipment, the protection of equipment is more perfect.General large UPS power supply must also be equipped with a voltage regulator bypass system (voltage regulator), the scope of the regulator is very wide, almost need to use electricity can be used (of course, the premise is the voltage instability).

The voltage regulator is composed of voltage regulating circuit, control circuit, and servo motor, etc.When the input voltage or load changes, the control circuit samples, compares, amplifies, and then drives the servo motor to rotate, so that the position of the carbon brush of the voltage regulator changes, and by automatically adjusting the coil turns ratio, so as to maintain the stability of the output voltage.

The usage of AVR：

1.It can stabilize the voltage of low-voltage 125V-165V or high-voltage 250V-270V between 200-230V, so that household appliances can work normally;

2.When the input voltage is higher than 255-275V or lower than 125-160V, it can automatically cut off the power supply;

3.After the power failure and a sudden call, you can delay 5-8 minutes to start the output power supply, to avoid electrical damage due to high voltage.In the purchase of household voltage regulator must pay attention to the above three basic functions are complete or not.

Stabilized power supply is mainly used to stabilize the voltage, to provide a stable electricity environment for electrical equipment, the use of electrical equipment from voltage fluctuations or interference.Because the function is completely different from the UPS power supply, and the UPS power supply also comes with an energy storage battery, so the price cost is relatively high.

, of course, there are a lot of people is to mix regulated power supply and UPS power makes sense, because some quality good backup UPS power supply is also attached with a voltage stabilizing function, is one of the electronic switch voltage regulator, can be used as stabilizer, but there is no specific voltage stabilizer effect and voltage stability and precision so ideal.

The Difference between UPS and AVR:

1.The UPS power supply acts like an emergency power supply, connecting to the mains and acting as an AC mains voltage regulator, while also charging the batteries inside the machine.When the power supply is interrupted, UPS will supply 220V AC to the load through the method of inverter conversion, so as to ensure that the server in the machine room will not be cut off.

2.AVR cannot provide backup power for the server when the mains power is interrupted. It is only designed for voltage instability. It is mainly used to protect the back-end equipment and has a more perfect protection function for the equipment.In cases where the voltage fluctuates, it is possible to use a regulated power supply, but it does not power the server.

3.The role and difference of AVR and UPS power supply are briefly introduced above. In fact, the biggest difference between the two is that the voltage regulator is only voltage regulator;UPS can not only play the role of voltage stabilization, but also by the battery inverter power supply after power failure, to ensure that the equipment does not lose power.

To sum up, the regulated power supply is the regulator that people say, it and the UPS power supply are two different concepts, many people always wrong to the regulator and the UPS power supply as the same product, there is a difference, not only is the function, structure or principle is not a concept at all.So when you buy it, you can choose according to your actual situation, and you must distinguish it.
