Product description
DK PDU international, switched, compact basic power distribution incl. energy measurement per phase, individually switchable output slots, with network interface and display, WLD: 44x1495x70 mm, IEC 60 320: 24x C13 + 6x C19
Per‑phase energy measurement with individually switchable output slots provides cost visibility and granular control. The business impact is reduced energy waste and targeted power-down during maintenance, minimizing downtime in critical IT racks for data centers and server rooms. The PDU's per‑phase monitoring supports accurate load balancing and capacity planning, while enabling chargeback for IT services. The rotatable display and replaceable control unit simplify field servicing, reducing mean time to repair and lowering maintenance costs during firmware updates or configuration changes. A fully redundant Ethernet interface with 10/100/1000 Mbit/s and PoE enables high‑availability remote management and seamless integration into existing monitoring ecosystems, improving operator confidence and uptime. Optional Type 3 overvoltage protection with arresters and residual current monitoring per infeed/phase/fuse address risk management and regulatory compliance for mission‑critical loads. Virginia IT teams often value the compact form, 24x C13 and 6x C19 outlets, and 400 V/16 A capabilities for scalable rack power.
