3.1.EM 6400 Technical Specs
The EM 6400 DigitAN series is a high-accuracy, low cost, ultra-compact, power and energy
meter that offers ISO 9001 quality, accuracy and functional flexibility and MODBUS RTU
communications capability. The standard unit flush-mounts in a DIN 96 cutout and conforms
to UL and CE safety requirements.
The EM 6400 DigitAN series is designed for retrofit application such as replacement of
existing analog meters and is also usable as a stand-alone meter in custom panels, PDUs,
switchboards, switchgear, UPS’s, generator sets, MCCs systems etc.
The EM 6400 DigitAN series provides easy communication to PLCs, DCS, BMS and other
systems through the use of Modbus RTU communications on RS 485, with isolation voltage
minimum 2kV for 1 minute, from other circuits.
The EM 6400 DigitAN series of meters are configurable & user programmable through the
front panel.
