Select the meter and communication module as one ordered configuration
- This reviewed meter is a three-phase four-wire CT-connected design. It is not a single-phase, direct-connected or DIN-rail meter.
- Confirm the primary CT ratio and the 5 A secondary circuit before wiring or register mapping is released.
- RS485 and infrared are documented interfaces; PLC, RF, 2G, 3G and 4G are plug-in module options, not simultaneous standard equipment.
- Confirm the HES data profile, protocol, security responsibilities and remote-upgrade policy before the pilot.
- Regulated billing use depends on destination-country approval, utility acceptance, markings and the exact ordered configuration.
Typical applications
- CT-connected three-phase metering in commercial and industrial installations
- AMI pilots that require a replaceable PLC, RF or cellular communication module
- Bidirectional active and reactive energy collection for monitored import and export
- Remote meter-reading projects using an approved HES or customer data platform
