The advancement of human society is inseparable from the efforts of all walks of life, and the upgrading of various electronic products is inseparable from the efforts of the master. In fact, many people don't understand the composition of electronic products such as UPS. UPS uninterruptible power supply, its important function is to supply uninterruptible power supplies for single computers, computer network systems or other power electronic devices.

When the market is normally, the UPS uninterruptible power supply will stabilize the market and supply load. At this time, the UPS uninterruptible power supply is equivalent to the exchange of electric motor regulators, and also charging the battery in the machine. When the market is interrupted, the UPS will immediately use the battery power in the machine through the inverter conversion to supply 220V alternating current to the load, thereby keeping the load normally and protects the load hardware.

The UPS power system is a high-tech product developed to meet the demand of the power market. It has obvious power maintenance. When the main power is cut, it will continue to supply power to the load; when the power is unstable, it can prevent the load from being owed.

Pressure, surge impact, etc., comprehensively improve power quality. When a power system (including UPS) fails, it can supply comprehensive maintenance for load (especially computer and network systems), and prevent overload, short circuit, preventing battery over-discharging for battery supply stable working environment.

UPS power purchase UPS can use at least 3 years. When selecting the UPS power supply, the user should determine the selection criteria according to their own requirements, and select the UPS that best suits their business needs, not the cheapest or highest-end UPS. Before purchasing UPS, users should consider the importance of data, such as load devices, power quality requirements, installation and spatial requirements, and economic budgets of various electrical equipment.

Next, the user should understand the required UPS capacity and consider the total capacity when expanding the device in the future. Choosing a reputable brand and manufacturer is also important. Of course, when purchasing UPS, it should also pay attention to its output power, power supply time, output voltage waveform, instantaneous response characteristics, output frequency stability, waveform distortion coefficient, output voltage stability, safety performance, maintenance performance and price.

Regarding the computing center and network management centers that require high power supply, in order to ensure that power supply is unlucky, it is usually necessary to use a redundant power supply system with "fault tolerance" function: 1) Host - slave "hot backup" redundant power supply system : The basic structure is to connect the AC bypass of the primary UPS to the inverter power output from the UPS. In case the master USP fails, it can be loaded from UPS. This redundant working method is limited due to the lack of the possibility of "capacity extension" and 4 millisecond power supply interruptions.

2) Use a dual redundant power supply system: by placing two UPSs having the same power output with the same amplitude, the same phase, and the same frequency state, combine them directly in parallel. The development trend of the UPS power supply With the continuous development of new technologies, the gradual application in practice can foreseeable, in the future, the UPS power supply will move toward high frequency, intelligence, networked and large-capacity single redundancy development. High frequency: Although traditional online technology is very mature, it has many problems that cannot be overcome, thus limiting its development prospects.

The introduction of high-frequency concepts has brought many new ideas and spaces for the development of UPS. With the development of high-frequency technologies and equipment, high-frequency online UPS technology and products below 3KVA have matured, and their function and reliability should be higher than traditional UPS, while high frequency plays an important use in it. Reduce the volume, reduce costs, and better respond to nonlinear loads.

Intelligent: The application of microprocessor in UPS in the past only in large and medium-sized UPS. In recent years, it has gradually developed into small and mini UPS. The result is the intelligent development of UPS, including control, detection, and communication.

UPS is gradually managed by computer, computer and peripherals can "autonomously" process some predictable problems that may have, can perform automatic management and adjustment, and can transfer relevant information to the operating system or network administrator through the network. Remote operation is very convenient. manage.

Network: UPS as a member of the network family is becoming more and more urgent, because it is the basis of the normal operation of the network. The UPS should have a larger power storage capacity, which can serve multiple computers or other peripherals, and can achieve dynamic configuration between the load through a certain mechanism. Large-capacity stand-alone redundancy: Since the network is getting higher and higher in the network, the method of solving reliability is to use redundancy in addition to the high reliability of the component itself.

Redundancy appears in a single small capacity UPS. Large capacity UPS must be implemented in parallel. .
