Power Distribution Unit

For power distribution requirements of medium to large data centers, Delta’s Power Distribution Unit (PDU) provides an optimal solution. The space-saving PDU is easy to move and adapt to future reconfigurations of the data center. The PDU offers superior power protection and monitoring, and the flexibility & scalability to match your actual power distribution requirements. Not only does it improve availability, it reduces the cost of your initial investment.
