The EM9400 from TRINITY is an easy to use, cost effective electrical power meter that offers all basic measurement cababilities required to minitor an electrical insulation. In addition to measuring the instantaneous parameters, it also measures all three energies, thus helping to measure energy costs.
Over the basic metering, it provides RS485 port supporting MODBUS RTU protocol, THD measurements, phase angle, unbalance percentage for voltage & current, ON hours, RUN hours, power interruption recording. These parameters are available with RS485 only. The CT primary/secondary & PT ratios are site selectable.
