What's the difference between the role of stabilizer and UPS power supply? - - - - - -

UPS power supply is divided into on-line UPS power supply and backup UPS power supply, general equipped with home computers is belongs to the backup type of UPS power supply, it belongs to a kind of backup power; Backup type is with regulated part, USES the relay shift voltage regulator, voltage stabilizing effect is not very good, so can't called voltage regulator. UPS power supply's role is as a reserve power to use, after the blackout, through summary storage battery power after inverter output ac current to the power supply equipment using, because 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. The voltage regulator is designed for power grid voltage instability, primarily for the backend equipment protection, to protect equipment function better. General large UPS power supply will need to be equipped with bypass system voltage ( Voltage stabilizer) , voltage regulator has a very wide range of scope, where the voltage instability can be used. By the pressure regulator circuit, control circuit, and the servo motor, etc. When the input voltage or load change, sampling and comparison are made on the control circuit, amplifier, and then drive servo motor rotation, and change the position of the voltage regulator for carbon brush, by automatically adjusting the coil number of turns ratio, so as to maintain the stability of output voltage. And the function of the voltage regulator: 1, can make low voltage 125 v - Or high voltage 250 v - 165 v Voltage stability is in 200-270 - v Between 230 v, make household appliances can work normally; 2, when the input voltage is higher than 255 - V or below 125-275 When the 160 v, can automatically cut off power supply; 3, when power is suddenly call afterwards, can delay 5 - 8 minutes to start the output power, avoid because of the high voltage electrical damage. When the choose and buy home voltage stabilizer must pay attention to the above three basic function is complete or not. As emergency power supply, UPS power supply, it was connected to the mains, ACTS as an ac mains voltage regulator, at the same time also to the internal battery. When mains interruption, UPS will internal battery power, by using the method of inverter transformation to the load continues to supply 220 v alternating current (ac), to ensure that the room server won't power outages. And voltage regulator it not for the server to provide back-up power at mains interruption, designed only for voltage instability, back end equipment is mainly used for protection, function more perfect for protection of equipment. In voltage instability, high and low, you can use a regulated power supply, but not for the server power supply. Voltage regulator only regulated; UPS will not only have voltage stabilizing effect, after the blackout can also by continuing battery inverter power supply, ensure the electrical equipment. Regulated power supply is mainly used to voltage stability, to provide a stable electrical equipment electricity environment, use of electric equipment from voltage fluctuation or interference. Due to function fully and UPS power supply, and UPS power supply which also comes with a storage battery, so the cost of the price is quite high. 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 still no specific voltage stabilizing effect and voltage regulation precision voltage regulator to do well. Namely stabilizer only regulated; UPS will not only have voltage stabilizing effect, after the blackout can also by continuing battery inverter power supply, ensure the electrical equipment.
There are a wide variety of which are scientifically tested to have positive effects on the ability to three phase voltage regulator. stabiliser for ac Video is one of them.
