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.

Product description
DK RCM measuring module – inline meter, autonomous energy acquisition unit, for PDU basic or modular PDU without measuring functions, 1 U, 482.6 mm (19"), incl. sensor interface, rated power: 22.0 kW, rated current: 32 A, 3~, connection type: CEE connector/coupling, connection cable / length: H05VV F5G4.0 / 1 m, extruded aluminium section, anodised, RAL 9005
The DK 7979.714 is an autonomous energy metering module that fits in a 1U/19" rack space, offering 22 kW of monitored load and a 32 A three-phase rating. Business impact: enables modern energy accounting and upholds compliance in compact rack installations, reducing the need for standalone meters and simplifying upgrades. Application: ideal for PDU basic or modular PDUs without built-in measuring functions, allowing rapid retrofit without extensive rework. The unit includes an integral differential current measurement (type B) for fault current monitoring, supporting faster fault isolation and improved safety in cabinet clusters. Application context: data centers and manufacturing cabinets rely on continuous power visibility to optimize uptime and energy costs. The device logs all key electrical characteristics and provides convenient data access via a network interface or the built-in TFT display, streamlining audits and reporting. Compatibility: supports PDU metered interfaces and external sensors via the optional CMC III CAN bus, enabling ambient monitoring without additional space. Durability: extruded aluminium, anodised, in RAL 9005, designed for demanding industrial environments and consistent long-term operation. Installation efficiency: 1U form factor, CEE coupling, and standardized 2 m input and 1.2 m output cables simplify integration with existing cabling layouts.

FAQs
Begin by confirming the 1U/19" form factor fits your rack, then mount the unit into the PDU space using the supplied hardware. Connect the input via the 2 m H05VV-F5G4.0 cable to the infeed and route the 1.2 m output cable to the PDUs or downstream devices. Ensure the CEE connector/coupling is securely seated and verify Ethernet connectivity for data access.
Key specs include 32 A rated current, 3-phase design, 22 kW rated power, and a 1 U, 482.6 mm wide footprint. It uses a CEE connection, provides 10/100/1000 Mbps Ethernet with PoE on one port, and supports 2 m input and 1.2 m output cables. The device also includes differential current monitoring (type B) for fault detection.
Yes. Its autonomous metering capability, network logging, and Etherner connectivity enable continuous power monitoring, usage analytics, and integration with energy management workflows in data centers. The ability to log all key electrical characteristics supports audits, capacity planning, and compliance reporting in mission-critical environments.
The DK 7979.714 adheres to the Low Voltage Directive 2014/35/EU and EN 62368-1, with CE marking. These certifications ensure safety and interoperability across European installations, and simplify regulatory approvals for cabinet and PDU deployments in industrial settings.
Maintenance is minimal due to passive sensors and local TFT display plus network access for monitoring. ROI comes from improved energy visibility, reduced unplanned downtime through fault detection, and easier regulatory reporting, especially in multi-rack environments. Upgrading existing PDUs to metered operation can lower energy waste and enable data-driven optimization.
