DTS719 is a transformer-operated three-phase smart meter with an embedded radio-frequency (RF) solution for local meter access. It is designed for connection to current transformers (CT) and for additional connection to potential transformers (CT/PT).
The DTS719 is used to measure electrical energy accurately for commercial and industrial customers. With the RF communication and a hand held unit (HHU) various smart metering functions can be realized without extending the existing infrastructure. The communication with the meter is DLMS compliant. The built-in tariff structures are supporting active, reactive and apparent measurement modes.
