A voltage regulator is a device designed to automatically maintain a constant voltage, and its main functions include the following aspects:

（1） Compensation principleThis compensating voltage regulator is based on the principle of electromagnetic induction to achieve stable voltage regulation. When the input voltage changes, the compensation winding inside the voltage regulator will automatically adjust the magnetic flux according to the voltage fluctuation. By changing the number of turns or current magnitude of the compensation winding,

The working principle of an inverter is to high-frequency switch DC power through electronic switching devices, forming a pulse width modulation (PWM) signal, and then convert the pulse signal into AC power through a filter. The basic structure of an inverter includes DC power supply, switching devices, control circuit, and output filter.

Performance and characteristics of rectification and voltage regulation power supplyRectification and voltage stabilization are commonly used concepts in the field of electronics to control the effectiveness and stability of power output voltage. Rectification converts AC power from a power source into DC power and converts it into a stable output current; Voltage stabilization is achieved

When selecting a generator set, it is not only necessary to consider the power matching, but also to have a deep understanding of the excitation type of the generator, which is beneficial for the normal operation of the UPS power supply.

1. Firstly, the packaging of the battery should be checked for damage, and then the packaging should be carefully opened to check whether the batteries are ingood condition one by one; And check the factory date of the battery to determine the time when the battery needs to be recharged when it is put into
