Product information "EMU Professional II 3/5 M-Bus"

The 3-phase bidirectional power meter EMU Professional II 3/5 M-Bus for DIN rail mounting is suitable for energy management as per ISO 50001 and energy cost billing.

Features

• Bidirectional three-phase power meter with M-Bus interface
• wired M-Bus interface
• 3x230/400V
• Indirect using /5A and /1A current transformers
• Current transformer ratio configurable several times using the service key
• MID B+D, for billing purposes
• Accuracy class B (1%)

M-Bus interface

The built-in M-Bus interface is protected against dirt and manipulation and is designed according to EN13757-2, -3 (previously EN1434-3).
The power meter EMU Professional II 3/5 M-Bus communicates via M-Bus at 300, 600, 1,200, 2,400, 4,800 and 9,600 baud.
The M-Bus load of the EMU Professional II 3/5 M-Bus is only 1.5 mA, which corresponds to a standard load.
M-Bus connection: The EMU Professional 3/5 M-Bus 2x2 M-Bus connection terminals for easy M-Bus looping.

Power meter readings

• Active energy consumption (kWh) and supply (kWh)
• Reactive energy consumption (kWh) and supply (kWh)
• Active power (kw) 
• Reactive power (kvar) 
• Apparent power (kVA)
• Current (A)
• Frequency (Hz)
• Number of voltage failures
• Current transformer ratio

LCD-Display

Reading and setting parameters is user-friendly by a 38x28 mm graphic LCD display with LED backlight. This provides excellent visibility of numbers and letters.
Display language e.g. english or german can be selected by the keys.

Power meter configuration

Touch-sensitive control buttons are used for configuration. A sealable service button must be pressed for each configuration change.
The current transformer ratio (1 or 5 A transformer, up for up to 20000/5 or 4000/1 A) can be configurable several times.
The control keys are used to configure the M-Bus primary and secondary address, and the baud rate.

• M-Bus baud rate: Via keys or free EMU MB-Connect software
• M-Bus primary address: Via keys or free EMU MB-Connect software
• M-Bus secondary address: Via keys or free EMU MB-Connect software

S0 pulse output

The 3-phase indirect power meter EMU Professional II 3/5 M-Bus features a configurable S0 pulse output for active or reactive energy 

• Pulse rate per kWh / kvarH: 1,10,100, 1000 or 10000
• Pulse length in milliseconds: 2ms, 10ms, 30ms, 40ms, 120 ms

Indirect power meter configuration ex factory

• M-Bus secondary address: serial number, e.g. 28521234
• M-Bus primary address: 000
• M-Bus baud rate: 2400
• S0 pulse output: 10 Impulse/ 20 ms
