EMU Professional II 3/100 M-Bus LP

The three-phase meter EMU Professional II 3/100 M-Bus LP is an energy meter suitable for EEG third-party quantity delimitation, which has a MID B+D and PTB-A 50.7 approval. The M-Bus interface according to EN13757-2, -3 (formerly EN1434-3) is integrated in the EMU Professional II 3/100 M-Bus LP and protected against manipulation and contamination.

M-Bus interface

This load profile meter with its integrated M-Bus interface meets the requirements of EEG third-party quantity delimitation for own power generation. The M-Bus-capable three-phase meter EMU Professional II 3/100 M-Bus LP communicates via M-Bus at 300, 600, 1’200, 2’400, 4’800 and 9’600 baud.

Configuration

On the EEG meter EMU Professional II 3/100 M-Bus LP, configuration is carried out via touch-sensitive buttons.

• Pulse rate and time
• M-Bus address
• M-Bus baud rate

These touch-sensitive control buttons can be used to set the primary and secondary address and baud rate. The M-Bus load of the EMU Professional II is only 1.5 mA, which corresponds to a standard load.

S0 pulse output

The EMU Professional II has a configurable S0 pulse output

• Active energy import or active energy export
• Reactive energy import or reactive energy export

Factory configuration

• Direct connection: 1'000 pulses/ 40 ms
• Baud rate: 2400
• M-Bus primary address: 000
• M-Bus secondary address: corresponds to the serial number, e.g. 21081234
