Power UPS power supply is a special power supply product designed for uninterrupted AC power supply systems such as power plants, substations, distribution stations, post and telecommunications, railways, etc., with double conversion online, zero conversion and fault bypass functions. This series of products is using advanced DSP digital control technology, high-frequency switching technology, so that the series of products better quality, better performance, easier to install and maintain.

◆ Fully adopt DSP digital control technology, the product is more stable and the quality is superior.

◆ Input and output are equipped with isolation transformers for high reliability.

◆ Optional dual power inputs

◆ Serial redundant backups for better reliability

◆ Small size, light weight, easy maintenance

◆ The load power factor is 0.8 and is designed according to the latest electrical equipment standards.

◆ The active input power factor correction (PFC) is as high as 0.98 or more, which avoids pollution to the power grid environment and meets the social requirements of energy conservation and environmental protection.

◆ The wide input voltage frequency range enables normal power supply even in remote areas with very harsh power environments.

◆ Zero switching ensures that the powered equipment will never be powered.

◆ Convenient remote monitoring function, providing standard RS232 interface, optional dry contact, RS485, and network monitoring card.
