RDH series special UPS (special inverter 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.
RDH series special UPS (special inverter 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.
◆ Fully adopt DSP digital control technology, the product is more stable and the quality is superior.
◆ DC self-start function, in DC mode, DC voltage out of range, dedicated UPS turn off the output, when it returns to normal value, dedicated UPS automatically boots.
◆ The load power factor is 0.8, which is designed according to the latest electrical equipment standards.
◆ Active input power factor correction (PFC) is as high as 0.98 or more, avoiding pollution to the power grid environment and meeting the social requirements of energy conservation and environmental protection.
◆ Wide input voltage frequency range can supply power normally even in remote areas with very harsh power environment, reducing the number of battery discharges and improving the service life of the battery.
◆ When the zero switching mains power is unstable, the conversion time of the UPS power supply mode is zero, which effectively ensures the safety and reliability of load operation.
◆ Convenient remote monitoring function, providing standard RS232 interface, optional dry contact, RS485, and network monitoring card.
