FAQs
The DK 7979.438 PDU is designed for VX IT enclosure systems and can be mounted in zero-U space. It supports vertical installation in VX IT frames and TS IT racks, enabling space optimization without tools. This makes deployment faster and reduces disruption in busy data centers while preserving cabinet integrity and airflow management.
Each output slot provides energy measurement and monitoring, enabling precise chargeback and load balancing. This visibility helps identify inefficiencies, prevents overheating from uneven loads, and supports compliance reporting. Combined with per-outlet alerts, it reduces risk of outages and improves capacity planning for IT networks.
Yes. The PDU is CE marked and conforms to EMC Directive 2014/30/EU, with EN 62368-1 safety standard compliance. These certifications assure regulatory alignment for IT equipment, reduce procurement risk, and support audit-readiness in regulated environments such as financial data centers and healthcare facilities.
The unit supports type 3 overvoltage protection with interchangeable arresters, residual current measurement (type B) per inlet/phase/fuse, and optional ambient CAN bus sensors for environmental monitoring. These features improve fault detection, enhance safety, and help maintain optimal operating conditions across the data center footprint.
With per-outlet energy data, remote monitoring, and robust protections, operators can optimize energy use, reduce waste, and minimize unplanned downtime. The web/server access via PoE streamlines maintenance, while compatibility with VX IT frames simplifies future upgrades and capacity expansion, delivering measurable ROI over the equipment lifecycle.
