Design
32 A / single-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 module in a 1U/19" form factor integrates directly into the power feed to equipment, enabling plug-and-play PDU upgrades with minimal footprint impact. Business impact: faster deployment, reduced wiring complexity, and immediate access to real-time energy data for consumption analysis and billing. Application: upgrades for basic or modular PDUs lacking measurement functions, with a clear path to energy management dashboards and reporting. Differential current measurement (type B) provides fault current monitoring, increasing safety and reducing downtime risk in critical equipment racks. Application: IT rooms and manufacturing lines where early fault detection matters. All key electrical characteristics are logged and retrievable via a network interface or TFT display, enabling compliance reporting and energy analytics. Application: data-driven maintenance, chargeback precision, and performance benchmarking. Fully redundant Ethernet interfaces (10/100/1000 Mbps) with PoE support ensure robust remote monitoring. Application: scalable monitoring in data centers and automation networks with minimal risk of communication outages. Additional sensor interfaces and up to 16 ambient CAN bus sensors (CMC III) give extended environmental visibility. Application: proactive environmental control and reliability improvements in mixed-signal environments. The rugged, extruded aluminium housing (RAL 9005) supports demanding installations, while the modular cabling (2 m input, 1.2 m output) simplifies installation and service. Application: quick commissioning and easy replacement in constrained rack spaces.
