Three-phase energy meter EK-MS1-TP-20D

single-phasedigitalmulti-circuit

Description
What cannot be measured, cannot be improved: Ekinex supports the energy efficiency of buildings with its Smart Metering solution. The KNX three-phase secondary electricity meter is designed to measure active and reactive energy with bidirectional counting (import/export). It publishes electrical parameters on the KNX bus for integration in building energy management and automation systems.

Technical data

• Rated voltage Un: 3x230/400 V AC (±20%)
• Rated frequency fn: 50 Hz
• Direct connection current Imax: 20 A
• Bus current consumption: < 10 mA

Supply
A terminal for connection to the KNX bus line is included in the scope of supply.

Functions / Features

• OLED display for measured values and diagnostic information
• Bidirectional measurement of active and reactive parameters for single-phase and three-phase circuits
• Three measurement circuits; each can be used as an independent single-phase circuit
• Direct connection via screw terminals; cable cross-section up to 4 mm²
• Accuracy better than 2%
