Article number
DK 7979.713
Design
16 A / three-phase
Product description
Autonomous energy metering unit (including differential current monitoring) in a 1 U/19" form factor. The unit is incorporated into the supply lead to the equipment, a PDU basic or a modular PDU without measurement function. All key electrical characteristics are logged in the same way as with a PDU metered. Additionally, the measurement module features an integral differential current measurement (type B) for fault current monitoring of the connected equipment. Consumption data is conveniently retrieved via a network interface or locally via a TFT display. Additionally, all the PDU metered interfaces, e.g. for connecting external sensors and smart handle systems, are available.

Inline energy metering with differential current monitoring logs key electrical characteristics, enabling accurate energy accounting and faster fault isolation for PDUs. This translates to measurable business impact: reduced energy waste and improved uptime, particularly in data centers where per-outlet consumption data drives optimization of cooling and power provisioning. The 1U/19" form factor fits standard racks, simplifying retrofits into existing cabinets and modular PDUs while preserving space for other components. In practice, technicians gain a seamless upgrade path that minimizes downtime during installation and supports scalable energy management across growing infrastructure. The network interface provides remote data access and local TFT display options, delivering actionable insights at the operator console and via centralized monitoring systems. Compatibility with external sensors and smart handle systems further extends environmental visibility without costly rewiring. The rugged aluminium enclosure, anodised in RAL 9005, offers industrial durability for demanding environments, while a CEE connector and supplied H05VVC cables simplify integration with new or legacy power chains. Designed to meet EN 62368-1 safety standards and the Low Voltage Directive, the unit supports compliant deployments and long-term Total Cost of Ownership reductions for energy-aware operations.

FAQs
Install the 1 U/19" module into compatible PDUs or modular PDUs without measurement functions. Use the included H05VV-F2.5 cables (2 m input, 1.2 m output) and connect via the CEE coupling. The device fits standard 19" racks and interfaces with a 10/100/1000 Mbps Ethernet network (2x RJ45, one PoE). The TFT display option allows local readouts, reducing remote access steps.
It delivers 11 kW rated power, 16 A rated current, and three‑phase input (3~), enabling precise inline energy measurement and differential current monitoring for fault detection. The module supports external sensors up to 16 via CAN bus and provides robust network access for centralized energy auditing and capacity planning.
Yes. The device adheres to the Low Voltage Directive 2014/35/EU, enabling CE marking, and complies with EN 62368-1 safety standards. This combination supports safe operation in industrial and data center environments and facilitates regulatory approvals for installations.
Yes. The unit offers an option to connect CMC III CAN bus ambient sensors, with support for up to 16 sensors. This enables environmental monitoring alongside electrical measurements, helping optimize cooling strategies and prevent environmental excursions.
By providing detailed energy data and fault visibility, you can reduce energy waste, optimize load distribution, and shorten downtime due to faults. Local TFT readouts and remote network access streamline audits, leading to faster decision-making and a clearer path to regulatory compliance and maintenance planning.
