Beschreibung
The EMU Professional is a multifunctional energy meter with a slim design of only 90 mm (5HP) and outstanding flexibility and accuracy. Via direct or current transformer connection it helps to analyze and monitor a wide range of parameters in the most demanding applications in residential, commercial or industrial environments. It combines different functions of a multimeter and a power and energy meter. The TCP/IP module allows you to view all parameters via a password-protected website. Or even simpler: If defined measured values are exceeded or undercut, the module sends you an e-mail or SMS. The EMU Professional is manufactured in accuracy class B (+/-1 %), class C (+/-0.5 %) is available on customer request.

4 S0 pulse outputs for active power in, active power out, reactive power in, reactive power out
Optional outputs: M-Bus, Modbus RTU, Modbus TCP, KNX, LON, LAN TCP/IP
4 S0 pulse outputs (Opto Power MOSFET, 5-400V AC or V DC, 90 mA) are available on the EMU Professional.
The pulse outputs can be reprogrammed as switches to switch a relay on or off. The pulse length and rate are configured via keys for optimal resolution.
