Electric.ie September - October Edition

ELECTRIC.IE • The Magazine & Website for the Irish Electrical Industry • 31 At A Glance – 4-quadrant energy meters – Display of: Active power (kW), reactive power (kvarh), apparent power (kVA), voltage (V), current – Special version: – Direct measurement up to 125 A (3-phase) – Energy meters 3 x 80 A (1-phase) – Interfaces: Pulse, M-Bus, Modbus – MID-compliant (except single-phase 3 x 80 A) Complete range Our comprehensive range of new energy meters provides end-to-end functionality. Plus a few highlights that you only get from Hager, for example direct measurement up to 125 A without a CT. Or the 3 x 80 A single-phase metering in a compact device (not MID-compliant). When integrated into a monitoring system, you therefore only use one instead of three bus addresses. The meters can be used as bidirectional meters for consumed and supplied mains power. They also measure the active, reactive and apparent power. All other meters (1-phase 40 A/80 A and 3-phase) are MID-compliant and suitable for billing purposes. Numerous interfaces The new energy meters communicate via all common interfaces; depending on the design via pulse measurement, M-Bus (common in residential buildings) or Modbus (predominantly used in commercial buildings). The Modbus devices are equipped either with screw-fastening technology or with practical plug-and-play plug-in technology. In the case of the latter, an RJ45 connector with protection against reverse polarity guarantees fault-free connection and, if necessary, quick connection to our agardio.manager energy monitoring server – another important component of energy management of the future. Intelligent metering, billing, saving Energy meters Saving and billing energy requires the energy to be made visible. This involves measuring, converting and transmission of data. This requires energy meters that can record all energy consumption precisely, and are compatible with all common communication interfaces. The new generation of energy meters provide tailor-made solutions for all applications. Powerful, compact and with all common communication interfaces. For intelligent energy monitoring in residential and commercial buildings.
