Working Principle of Kehua Jingwei Frame UPS Power Supply

Nowadays, machine rooms, system integration and integrated cabinets are everywhere. The existence of rack UPS power supply has solved many problems. It is of great help to many machine rooms, data centers, workshops and units. The existence of rack UPS batteries is inevitable. Frame UPS frame design, shape design using the current most widely used 19-inch standard frame type chassis, simple appearance, easy installation.

Frame UPS is the third generation of power-frequency on-line intelligent UPS developed by new digital technology, aiming at the reliability requirements of power supply in China's power grid environment, network monitoring and network system, medical system, etc. to overcome the increasingly harsh environment of power supply network caused by centralized power supply of medium and large computer network systems. It is an important power supply equipment for enterprises.

Kehua Jingwei Frame UPS power supply is widely used in communication, power, public security, fire protection, radio and television, finance, military, Internet and other industries. The equipments matching and integrating with it are: communication base station, integrated distribution cabinet, data center, modular integrated products, etc. widely used in communication, power, public security, fire protection, radio and television, radio and television, etc. In finance, army, Internet and other industries, the equipments matching and integrating with them are: communication base station, integrated distribution cabinet, data center, modular integrated products and other fields.

Kehua Jingwei Frame UPS power supply system consists of five parts: main circuit, bypass circuit, battery and other power input circuit, AC/DC converter rectifier (REC), DC/AC converter (INV), inverter and bypass output switching circuit and energy storage battery.

Usually, the city electricity is converted into DC by rectifier to float charge the storage battery. At the same time, the high quality AC purifying power supply is output by inverter to provide important load, so that it is not disturbed by the voltage, frequency and harmonic of the city electricity. When the city power is cut off for some reason, the system automatically switches to the battery group, the battery discharges, and supplies power to the important load through the inverters.

The working principle of Kehua rack UPS:

Kehua rack UPS power supply will rectify the AC current of the municipal electricity when the machine is electrified, and store it in its own power supply. Once the power supply is stopped, it can provide power. It can use electrical equipment to maintain a period of working time. The holding time may be 10 minutes, half an hour, etc. The delay time is generally determined by the capacity of the battery.

In the power supply of municipal power, it is the function of regulator and filter to eliminate or weaken the interference of municipal power and ensure the normal operation of the equipment; when the municipal power is interrupted, it can also convert the DC power supplied by its DC power supply part into perfect AC power supply load, in which the power supply from municipal power to batteries is generally 0. Time switching, so that the load device can not feel any changes while maintaining operation, truly ensuring the uninterrupted operation of the equipment.
