Product description
A power meter and switching functions for the output slots can be added to any PSM busbar with these PSM plug-in modules. The modules are also suitable for upgrading existing PSM installations if it becomes necessary to record the power data or add a switching option for the connected equipment. There are three variants available with different socket types. In the PSM busbar, the PSM modules occupy two module slots each. Measurements are displayed locally on a backlit LC display. For quick checks, the colour changes to red if current and power limits are exceeded.

Product description
DK PSM measuring module, for modular PSM power distribution. Occupies 2 slots in the busbar. Output: 4 x protective contact, CEE 7/3, 2 x C13, input: 207 V – 250 V, 16 A, (max. 3680 W)
Feature: Plug‑in measurement module for PSM busbars. Business impact: Simple, rapid deployment with minimal risk and reduced installation time. Application: Upgrade existing PSM layouts to capture real‑time energy data without re‑engineering the busbar. The system detects overload events and surfaces alerts through CAN bus, enabling rapid corrective action and minimizing downtime. Feature: Per‑module energy measurement with local display. Business impact: Operators get immediate, module‑level insight (V, A, Hz) and visual limit indication, improving fault isolation and maintenance planning. Application: Use in machine lines and control panels where precise energy accounting is required for energy‑efficiency programs. Feature: 2‑slot footprint occupying 2 module slots on the busbar. Business impact: Maximizes space efficiency in compact assemblies while preserving expandability. Application: Suitable for modular installations in automation cabinets and panel boards where space is at a premium. Feature: 4 outputs (2 x C13, 4 x CEE 7/3) and 230 V AC input up to 16 A. Business impact: Flexible power distribution with clear load separation and protection, reducing risk of overloading critical equipment. Application: Data center and industrial PLC rooms where separate outlets are needed for devices with distinct power profiles. Feature: CAN bus interfaces to CMC III, SNMPv3, Modbus/TCP, OPC‑UA compatibility. Business impact: Enables scalable monitoring, remote diagnostics, and integration with existing SCADA/EMS ecosystems. Application: Enterprise‑level visibility and automated alarm management for multi‑bus architectures. Feature: IP20 rating and robust mechanical design. Business impact: Safe operation in typical industrial environments with straightforward maintenance. Application: Indoor electrical cabinets and machine enclosures where ingress protection is essential. Feature: Meets standards: Low Voltage Directive 2014/35/EU and EN 50 600‑2‑2.

FAQs
The module occupies two busbar slots and is designed for plug‑and‑play installation. Simply slide it into the two required slots, connect the CAN bus to the CMC III system via the included 1 m CAN cable, and wire the 230 V AC input to the bus‑bar supply. The module provides no‑voltage risk during installation due to its protective enclosure and clear local display for quick verification.
It measures voltage (V), current (A), and frequency (Hz) with a total distribution output of up to 3,680 W per module. The outputs include 4 x protective CEE 7/3 sockets and 2 x C13 sockets, with a maximum switching load of 4,000 VA per relay. The device uses a dual‑coil, bistable relay configuration for reliable switching.
Yes. Its CAN bus interfaces to CMC III, together with Modbus/TCP, SNMPv3, and OPC‑UA support, enables integration with SCADA and EMS systems common in data centers and manufacturing floors. The compact two‑slot form factor and plug‑and‑play approach minimize maintenance windows while delivering module‑level energy data for capacity planning and energy management.
The module conforms to the Low Voltage Directive 2014/35/EU and EN 50 600‑2‑2 standards, with an IP20 protection rating. It is CE‑compliant and designed for safe operation in industrial environments, aligning with typical European regulatory and safety expectations.
By enabling real‑time energy measurement at the module level and providing alarm management via CAN bus, you gain visibility into energy waste and overload risks, reducing unplanned downtime. The plug‑and‑play installation minimizes commissioning time, while long‑term data supports energy optimization programs and better asset utilization.
