KNX single-phase secondary
electricity meter
METERING
Description
The EK-MS2-TP-TA device has 2 independent measurement channels via external
current transformers (CT) and is suitable for measuring single-phase power lines
(230 Vac, 50-60 Hz). The flush-mounted box mounting is made in a compact case
with the possibility of mounting on a 35 mm DIN rail (EN 60715) using a special
adapter included in the supply.
Features
• Bidirectional measurement of electrical parameters for single-phase circuits
• Connection of measuring circuits to current transformers via screw terminals
• Accuracy better than 2%
• Connection to bus line via KNX terminal
• Up to 2 independent measuring circuits available
• Plastic housing
Technical data
• Supply voltage: 230 V AC
• Rated frequency fn: 50 Hz
• Current transformers from Imax 5 A up to Imax 120 A (not included in delivery)
• Current consumption from bus < 10 mA
