UPS power supply and related terms analysis

Do you know what UPS uninterruptible power supply is? What does it do? Today, Xiaobian is here for everyone to explain.

UPS is the abbreviation of uninterruptible power system. It is translated as uninterruptible power supply, referred to as UPS power supply. As the name suggests, it is uninterrupted power supply, and its characteristics are uninterrupted. For precision instrumentation, the power failure is very harmful to the UPS, and the UPS power supply can continue to supply power when the mains is interrupted, ensuring that the equipment can work normally.

In addition to interrupting the fault, the mains has many problems that people cannot see, such as harmonics, distortion, surges, surges, frequency drifts, etc. These problems have an impact on the accuracy and service life of the instrument. Therefore, in addition to uninterrupted power supply, UPS power supply also has the functions of voltage regulation, surge protection, harmonic distortion protection, and stable frequency.

The operating principle of the UPS power supply is as follows: when the utility power is normal, the utility equipment supplies power to the load device, and the rectifier or the charger supplies the UPS battery to float to keep the battery in a full state; when the utility power fails or is interrupted, The UPS turns on the battery power supply mode until the battery is discharged or the utility power returns to the mains operation mode, and then resumes charging.

*Related UPS uninterruptible power supply terminology:

1.W and VA

Both W and VA are the unit of capacity of the UPS power supply, W is the effective power, and VA is the apparent power. The nominal value of the UPS power supply is VA. The corresponding W value is given in the general technical parameters. There is a converted power factor between W and VA. For example, 400W/500VA can be used to derive a power factor of 0.8. This power factor is due to the fact that in an AC system, a portion of the current (harmonic current) is not supplied to the load, thereby producing an apparent power VA that is greater than the effective power W.

2. Standard machine and long machine UPS

The UPS uninterruptible power supply system is mainly composed of a UPS main unit and a UPS battery. When the battery is placed in the UPS main unit, it is the standard machine, and when the battery is not in the main unit, it is a long machine. The standard machine has a small capacity, and the power supply time is short after the power is cut off, generally 5-10 minutes; the long machine is an external battery, which is configured according to the power of the load and the time required for power supply.

3. Tower and rack UPS power supply

Tower and RackMount refer to the way the UPS is installed. The rack type is that the UPS main unit is placed on the rack, and the tower type machine is placed directly on the ground. The RM logo is rack-mounted, and the tower crane is not.

4. Power frequency machine and high frequency machine

The power frequency machine UPS is a UPS power supply using a power frequency transformer as a component of the rectifier and the inverter; the high frequency machine replaces the bulky power frequency transformer in the rectifier and the inverter with a high frequency switching element, and thus the high frequency machine is small in size. . Power frequency machines are widely used in telecommunications, securities, power, transportation, industrial and other industries. The high frequency machine is suitable for small and medium data centers, network management centers, enterprise server rooms, and the like.
