How to maximize the efficiency of your UPS

图片
1.Use of AC voltage regulator After using  UPS power supply , there is no need to add AC voltage regulator. If it must be added, it should be added to the front level of UPS, that is, the mains power first passes through the AC voltage regulator, then through the ups, and then to the load. 2.Battery balanced charging skills At present, valve regulated lead-acid battery (VRLA) used in many ups power supply is called maintenance free battery from the beginning, which gives users a misunderstanding that it seems that this battery is durable and does not need maintenance at all. Under this kind of misleading, many users have not carried out maintenance and management since they installed the battery. When the battery in UPS power supply meets the following conditions, the battery shall be charged evenly: when the terminal voltage is lower than the specified calibration voltage due to excessive discharge. For 12 V small sealed lead-acid batteries, the discharge calibration voltage is...

Matching between Generator Set and UPS

图片
Manufacturers and users of  UPS power supply system  have long noticed the matching problem between generators and UPS, especially the harmful effects of current harmonics generated by rectifiers on  power supply systems  such as voltage regulators of generators and synchronous circuits of UPS. Therefore, the technicians designed the input filter and applied it to UPS, and successfully controlled the current harmonics in UPS application. These filters play a key role in UPS compatibility with generators. In fact, all input filters use capacitors and inductors to absorb the destructive current harmonics at the UPS input. The design of the input filter takes into account the percentage of all possible harmonic distortion inherent in the UPS circuit and at full load. Another benefit of most filters is to increase the input power factor of UPS with load. However, another consequence of the application of input filters is to reduce the overall efficiency of UPS. Most...
