EMU Professional 3/5 KNX

The energy meter EMU Professional 3/5 KNX is certified according to MID B+D and features an integrated KNX interface. The three-phase meter is suitable for energy cost billing and for energy management according to ISO 50001.

KNX interface

The KNX interface is integrated in the EMU Professional and protected against contamination and manipulation. A wide variety of devices can be linked with each other using KNX. The EMU Professional communicates via KNX at 9’600 baud.

Functions at a glance

Measurable values on the energy meter

• Reactive power (kvar)
• Reactive energy inductive (kvarh) and capacitive (kvarh)
• Active power (kW)
• Active energy import (kWh) and export (kWh)
• Apparent power (kVA)
• Current (A)
• Number of voltage failures
• Mains frequency (Hz)

LCD display

The LCD graphic display (60x30 mm) facilitates the setting and reading of parameters thanks to LED backlighting. This ensures very good visibility of the digits.

Configuration

Configuration is carried out via the ETS software.

Adjustable pulse rate and time:

• Pulse length in milliseconds: 4 to 250 ms, adjustable in 2 ms steps
• Pulse rate per kWh: 0.001, 0.01, 0.1, 1, 10, 100, 1000 or 10000

Current transformer ratio

The current transformer ratio can be configured multiple times via buttons. The service button can be sealed.

• Current transformer /1 A 1/1 A to 4’000/1 A in 1 A steps
• Current transformer /5 A 5/5 A to 20’000/5 A in 5 A steps
