Understanding the Components and Functions of UPS Power Systems

UPS power system consists of 4 parts: rectifier, energy storage, conversion and switching control. The voltage stabilization function of the system is usually completed by the rectifier, rectifier parts using silicon controlled or high-frequency switching rectifier, itself has the function of controlling the output amplitude according to the change of the external power, so that when the external power changes (the change should meet the system requirements), the output amplitude of the rectified voltage basically unchanged.

The purification function is accomplished by the energy storage battery. Since the rectifier cannot eliminate the transient pulse interference, the rectified voltage still has the interference pulse. Energy storage battery in addition to the function of storing DC direct energy, the rectifier is like connecting a large container capacitor, the size of its equivalent capacitance, and the size of the storage battery capacity is directly proportional to the size. As the voltage at both ends of the capacitor can not be changed abruptly, that is, the use of the capacitor on the pulse of the smoothing characteristics of the pulse interference eliminated, played a purification function, also known as the shielding of the interference. Frequency stabilization is completed by the converter, frequency stability depends on the degree of stability of the converter's oscillation frequency. In order to facilitate the daily operation and maintenance of the UPS power supply system, the design of the system work switch, the host self-test fault after the automatic bypass switch, maintenance bypass switch and other switch control.

In the normal operation of the grid voltage, to the load power supply as shown, and, at the same time, to the storage battery charging; when a sudden blackout, the UPS power supply began to work, by the storage battery to the load of the power required to maintain normal production; when due to the production needs of the load serious overload, the voltage from the grid through the rectification of the load directly to the power supply.

UPS power system is mainly divided into two main parts, the host and the storage battery. The size of the rated output power depends on the host part, and with the load belongs to the nature of that, because the UPS power supply on the different performance of the load driving ability is different, usually the load power should meet the UPS power supply 70% of the rated power. The selection of storage battery capacity when the load power to determine the main decision of the length of the backup time, this time is different for each enterprise situation is different, mainly by the access time of the backup power to determine, usually in a few minutes or a few hours ranging from the UPS uninterruptible power supply is like a large charging treasure, has a power storage, regulated output, zero-second switching power supply in case of power outage, to protect the computer key data, to protect the health care and fire protection and other key areas of equipment normal operation. The UPS is like a large charging treasure, with power storage, stabilized voltage output, zero-second switching power supply during power failure, to protect computer critical data, protect medical fire and other critical equipment normal operation.

The GS and GM series are GEM BATTERY's most commonly used lead acid storage batteries for UPS power system products.

GS Series batteries have been developed from decades experience of manufacturing to meet various general-purpose and commercial applications. The batteries are AGM technology based products and complied with IEC61056-1/2 and IEC60896-21/22. GEM I GS Series batteries are in compact size with sealed maintenance-free design, quite flexible for multi-positioning installation and portable handling. The batteries could be applied for many civil applications, lamp and lantern, electric toys, power tools, civil or commercial UPS systems, emergency lights, security system, high-power mobile speaker and sound equipment, etc.... Moreover, the compact but high-energy-containing design could ideally support to commercial UPS systems, especially the 12V batteries with High-Rate (HR**) marked models are in great favor for industrial and critical UPS application.

GM Series batteries are designed at a larger size and higher capacity than GS Series and carrying more energy power to support more-power-requiring applications. The batteries are using GEM selected models of Pb-Ca-Sn alloyed plates for assembly and adopt AGM technology, complied with IEC60896-21/22.
