DELTAplusDescriptionTariffsThe DELTAplus range includes <strong>meters</strong> <strong>for</strong> 2 <strong>and</strong> 4 tariffs. Thetariffs are controlled via inputs or via communication.InstrumentationThrough the instrumentation functionality of DELTAplus,the following electrical properties can be read• Active power (per phase <strong>and</strong> total)• Apparent power (per phase <strong>and</strong> total)• Reactive power (per phase <strong>and</strong> total)• Current (per phase)• Voltage (per phase)• Frequency• Power factorThe DELTAplus is an advanced meter <strong>for</strong> installation inthree phase <strong>and</strong> single phase networks. The meter ismounted on a <strong>DIN</strong> <strong>rail</strong> <strong>and</strong> is suitable <strong>for</strong> installation indistribution boards <strong>and</strong> small encloses such as consumerunits. The meter measures active or combined (active <strong>and</strong>reactive) energy. The product supports a wide voltagerange <strong>and</strong> a wide temperature range which makes itsuitable <strong>for</strong> installation in many applications.General featuresDELTAplus is an meter that is easy to h<strong>and</strong>le. It is easy toread the large LCD display with 7 mm high digits <strong>and</strong> symbols<strong>for</strong> load indication, errors etc. The meter has LED on the frontthat flashes proportionally to the measured energy. The energyconsumption of the meter is very low, less than 0.6 VA.CommunicationData from DELTAplus is collected via pulse output or serialcommunication. The pulse output is a polarity independentsolid state relay that generates pulses proportionally to themeasured energy. DELTAplus can be equipped with built-incommunication interfaces <strong>for</strong> M-Bus or LonWorks FTT-10A.All DELTAplus <strong>meters</strong> come with an infrared port <strong>for</strong> communicationwith an external Serial Communication Adapter(SCA). There are SCAs <strong>for</strong> M-Bus, RS-232, Ethernet, GSM/GPRS <strong>and</strong> KNX.Inputs <strong>and</strong> outputsDELTAplus support two I/O’s. It can be two inputs or twooutputs or one of each. Outputs can be used <strong>for</strong> controllingexternal apparatus like a contactor or an alarm (max 120 mA).Inputs can be used <strong>for</strong> counting pulses from e.g. a watermeter, or <strong>for</strong> reading status from external devices.ConfigurationThe configuration of DELTAplus is simple. Using the two buttonsscroll <strong>and</strong> set you can configure trans<strong>for</strong>mer ratio, pulsefrequency, M-Bus address <strong>and</strong> baud rate when applicable.The two push buttons are under a sealable cover. When theyare sealed, the scroll eye on the fron of the meter can be used<strong>for</strong> reading the para<strong>meters</strong> <strong>and</strong> also instrument values.InstallationDELTAplus comes with an automatic installation check thatindicates problems in the installation.ApprovalDELTAplus is type approved according to IEC <strong>and</strong> it is bothtype approved <strong>and</strong> verified according to MID. MID is theMeasuring Instruments Directive 2004/22/EC from theEuropean Commission. MID type approval <strong>and</strong> verification ism<strong>and</strong>atory <strong>for</strong> <strong>meters</strong> in billing applications within EU <strong>and</strong> EEA.The type approval is according to st<strong>and</strong>ards that covers allrelevant technical aspects of the meter. These include climateconditions, electromagnetic compatibility (EMC), electricalrequirements, mechanical requirements <strong>and</strong> accuracy.2CMC480022C0003| <strong>Electricity</strong> <strong>meters</strong> 25
