EK-MS1-TP-TA Submeter

ORDERING CODE EK-MS1-TP-TA DESCRIPTION The ekinex® EK-MS1-TP-TA sub-meter is a KNX S-mode device, suitable for measuring electrical quantities and metering the energy produced and consumed in modern buildings equipped with renewable energy generation systems, storage systems, and subject to various loads such as heat pumps, vehicle charging systems, lighting, and household appliances. It has three independent measurement channels via external current transformers (CT) and can measure up to three independent single-phase power lines (230 Vac, 50-60 Hz) or one three-phase power line (400 Vac, 50-60 Hz). Designed for KNX standard building automation systems, it is equipped with a KNX bus communication module and can be easily integrated into the ekinex® delégo supervisor's consumption monitor: the delégo app offers a coordinated view of all acquired energy flows and immediate consultation of historical data. FUNCTIONS / FEATURES - Applications: 3 independent single-phase measurement channels (230 VAC, 50-60 Hz) or 1 three-phase (400 VAC, 50-60 Hz) - Current measurement method: using external current transformers (CTs) - Calculation of active power (kW), reactive power (kVAr), apparent power (kVA), power factor (cosφ), current (A) and voltage (V) measurement - Ability to account for total and partial energy, imported and exported - Graphic OLED display, 128x32 px, for displaying the measured electrical quantities - Availability of up to 8 comparators for values ​​above or below preset thresholds. The comparators can be applied to any electrical value acquired by the device. - 8 channels of AND-OR-XOR logic functions, 8 inputs per channel. - Communication interface: KNX TP. - KNX configuration: via ETS software. - Mounting on a 35 mm DIN rail. TECHNICAL CHARACTERISTICS - Measurement range: 0.2 A - 120 A - Current measurement range: 120 A max. per channel. - Voltage measurement range: 230 Vac for independent channels (50-60 Hz), 400 Vac for three-phase (50-60 Hz). - Current consumption from the mains: 12 mA @ 90 Vac, 6 mA @ 250 Vac. - Current consumption from the bus: 10 mA @ 21 - 30 Vdc. - Accuracy: depends on the current transformers used (see reference table). - PMD-II device class according to CEI EN IEC. 61557-12 - Logic part power supply (microcontroller): 230 Vac mains - 128x32 graphic OLED display, monochrome white - Operating temperature: -5°C to +45°C - Storage temperature: -30°C to +70°C - Maximum nominal enclosure temperature (tc): 80°C - Maximum humidity: annual average 75%, short-term 95%, non-condensing - Degree of protection IP20 - Dimensions (W x H x D): 71 x 90 x 62 mm - Weight: 300 g SCOPE OF DELIVERY The scope of delivery includes a terminal for connection to the KNX bus line. Current transformers (CT) can be ordered separately. CONFIGURATION AND COMMISSIONING A detailed description of the parameters can be found in the device's application manual. ETS5 or later is required for configuration and commissioning. Application program for ETS: APEKMSXTPX##.knxprod (## = version).
