DC POWER SUPPLY FOR DATA CENTERS
Ideal for Optical communication, Router, and Server power supplies
Power management design for global environmental conservation to reduce data center electricity operation cost by 20%
By converting communication devices such as routers, Windows servers, UNIX servers, storage, PBXs, and DWDMs from alternating current (AC) to DC power feed, running costs can be reduced by as much as 20% by reducing power loss and heat generation. In addition, the simplification of equipment circuitry not only greatly improves reliability, but also allows power to be supplied directly from the battery in the event of a power failure or malfunction, further increasing the reliability of the system.
The Rnet series is a power supply that converts AC to DC for data centers developed to meet this need for DC. We were also the first to commercialize a 380 V output model that can also support "high-voltage direct current power supply (HVDC power supply).
All the models feature highly reliable and ultra-thin, through our leading expertise in high-power DC power supplies. In addition to low running costs due to high efficiency, the power supply's ultra-slim profile makes it easy to store telecommunications equipment and greatly contributes to improving the profitability of system providers.
FEATURES

Functions
Advantages of DC
"There are three major advantages to DC power."
High Reliability
The mechanism of AC power supply is complicated because four elements must be controlled: "voltage," "frequency," "phase," and "waveform. On the other hand, with a DC power supply, only "voltage" needs to be controlled, which simplifies the structure. In the event of a power failure or malfunction, power can also be supplied from a backup battery.
Low Cost
The DC power feed will reduce electricity costs through superior conversion efficiency that only a simple configuration can provide. In addition, the heat generated by the equipment is reduced because there is little loss due to conversion, thereby reducing air conditioning costs.
Global Environmentally Friendly
It reduces electricity use and carbon dioxide emissions.
Advantages of space saving
The DC power supply eliminates the need for the power conversion unit of a conventionally used UPS and reduces the installation space.
Compared to AC-powered systems of the same capacity, it takes up only about half the space, allowing more routers and servers to be installed in the available space.
