Energy management & metering

Power meters, current transformers and concentrators for sub-metering, load monitoring and energy reporting.

Energy management starts with measurement. To see where energy is used, compare consumption over time or document savings, you need meters on the relevant circuits and a way to collect their data. ICP DAS supplies both: single-phase and three-phase power meters with current transformers (CTs), and concentrators that read many meters and pass the data on to SCADA, databases or cloud platforms.

Typical tasks

Sub-metering of buildings, departments, production lines or individual machines
Monitoring switchgear, distribution boards and generators
Load profiles and peak demand tracking
Energy reporting for audits, ISO 50001 or internal cost allocation
Temporary measurements during commissioning or energy audits

Power meters and current transformers

The PM series power meters measure voltage, current, power, power factor and energy on single-phase and three-phase circuits. Many models are supplied with matching current transformers, sized from small branch circuits to several hundred amperes. The meters communicate over Modbus RTU, with Modbus TCP and other interfaces on selected models, so any controller, BMS or SCADA system that supports these protocols can read them.

Power meter concentrators

A concentrator polls a group of meters and makes their data available in one place. The PMC series, and the PMD series with a built-in touch panel, collect data from ICP DAS meters, log it to a memory card and pass it on over Modbus TCP, MQTT, SNMP or FTP, depending on the model. Built-in IF-THEN-ELSE rules can switch loads off when demand approaches a limit. That gives a compact energy monitoring system without a separate server, or a clean data source for an existing SCADA.

Wireless and portable metering

Where cabling to every meter is impractical, iWSN wireless current sensing modules report to a concentrator over a wireless sensor network. For temporary measurements, a portable power monitoring kit packs the metering hardware into a carrying case.

Voltage and current signal conditioning

To measure high voltages and currents with standard analog input modules, voltage attenuators and current transformers from the DNM-800 range convert the signals to levels the I/O can read safely.

Example: sub-metering in a production building

Three-phase PM series meters with current transformers are fitted on the main incomer and on the feeders to each production line. A PMC concentrator reads them over RS-485, logs the values locally and sends them by MQTT to the energy reporting system. If the connection fails, the log on the memory card is sent once it is restored, so no data is lost.

What to check before you choose

Single-phase or three-phase, the nominal voltage and the maximum current of each circuit
CT type and size: the inner diameter must fit the cable or busbar
Which values are needed: energy only, or also power factor, demand and harmonics
How the data is collected: an existing SCADA or BMS over Modbus, a concentrator, or a cloud platform via MQTT
Space in the distribution board, measured in DIN-rail modules

We can help size meters and current transformers from a single-line diagram or a list of circuits.
