Converter counter

Bidirectional measuring transformer meter with M-Bus interface, 3x230/400V, current transformer /5 and /1A. The transformation ratio can be configured multiple times via buttons. Accuracy class B (1%), cumulative, MID B+D, factory calibrated for billing purposes. The 38x28 mm graphic LCD display, with its LED backlighting, allows for easy reading and setting of parameters with excellent visibility of the digits. Primary and secondary addresses as well as baud rate can be set using touch-sensitive control buttons. The M-Bus load of the EMU Professional II is only 1.5 mA, which corresponds to a standard load. The S0 pulse rate and time can be configured via buttons (1/10/100/1000/10000 per kWh).

The M-Bus interface is developed according to EN13757-2, -3 (formerly EN1434-3). The M-Bus electricity meter EMU Professional II 3/5 communicates via M-Bus at 300, 600, 1200, 2400, 4800, and 9600 baud. Primary and secondary addresses as well as baud rate can be configured using touch-sensitive control buttons.
