Application

MT418 is intended for measuring and monitoring singlephase current or frequency. Current input is electrically isolated from the system by means of current transformer. It measures RMS current value by means of fast sampling of current signals, which makes instruments suitable for acquisition of transient events. A built-in microcontroller calculates measurands (current, frequency, THD U, MD) from the measured signals. Measurands (I, f) can be then converted into load independent DC current or voltage which is proportional to the RMS measured value for the purpose of regulation of analogue and/or digital devices.

The MT418 programmable AC current transducer is used for a permanent monitoring of a single-phase current and frequency values. MT418 is delivered configured to default values. Subsequent customer configuration is possible with user friendly setting software MiQen. MT418 supports standard serial RS232/485 with speed up to 115200 bps. USB 2.0 can be used for a fast set-up or memory acquisition (after installation USB connection is not possible any more). Additional USB 2.0 interface can only be used for a fast setup without need for auxiliary power supply. This interface is NOT galvanically isolated from analogue output and can be used ONLY unconnected to aux. supply and measuring inputs.
