Product description
DK PDU metered+, compact basic power distribution incl. energy measurement per output slot, with network interface and display, WHD: 450x44x144 mm, CEE 7/3: 4 x earthing-pin
Energy measurement per output slot drives accurate chargeback and targeted optimization, reducing waste and cooling loads in dense IT racks. The business impact is tangible: deeper visibility translates to lower operating costs and smarter capacity planning in IT environments. Applications include data centers, server rooms, and network closets where precise per-outlet data supports service level alignment and cost allocation. The 482.6 mm (19") design enables seamless VX IT rack integration, with zero-U mounting in VX IT or TS IT frames for a compact footprint and faster deployment. A rotatable 180° display and replaceable controller unit simplify installation and servicing, while USB 2.0 supports mass configuration and firmware updates, minimizing maintenance windows. Optional CMC III CAN bus sensors allow ambient monitoring for proactive environmental control and compliance readiness.
