The consistent use of direct current in a data center makes sense. Losses can be massively reduced. On the power side, the IEC has defined the frame with TS 62735-1. Now it is the turn of the device side. AC and DC are supposed to coexist in a transition phase.
The lifecycles of the supply infrastructure (PDU) are generally longer than those of the devices to be supplied, which are replaced more frequently by technological developments. Regardless of this, the aim is now to provide an AC/DC device plug that allows the device to be operated on both an AC and a DC supply. This means that the change from the current AC supply can be switched to DC as required. Only the supply cables have to be replaced.
