400V DC Power

Rising energy costs, increasing power demand and mainstream adoption of renewable energy sources are all driving acceptance of new power architectures, such as 400V DC, that enable more efficient networks and businesses. With recent advances in power conversion technologies and rapidly increasing DC-based equipment growth, 400V DC power distribution is a compelling option to consider.

Using DC power equipment to feed and backup electronic equipment eliminates AC-DC conversion stages, which saves energy, reduces heat input in the room and requires less components. With fewer components that could fail, site reliability improves while TCO is reduced. Read more...

400V DC is suitable for several applications with varying drivers for each:

  • Telecom - Significant copper savings for telecom central offices
  • Data Center - Reduced power chain complexity delivers high availability and efficiency
  • Commercial Buildings - Local, renewable energy sources integrate easily in a 400 VDC microgrid
