Magnelab’s MGS-1800 is a three-phase Rogowski coil (rope CT) with a 4-20 mA DC output. Essentially, it is an integrator, AC current transducer or signal conditioner that is designed to convert the Rogowski coil input voltage to a DC output of 4 to 20 milliamperes. In order to function properly, the transducer has to use a DC loop power supply, which can operate from 8 to 35 volts DC. The flexible CT device comes with integrated screw terminals. This allows it to be easily and safely installed. The MGS-1800 is very different from the MGC-1000 AC Current Sensor with 5 Amp Output, which is a single phase AC current sensor that converts AC current ranging from 30 to 300 amperes to an AC current output.
The MGS-1800 features include the fact that it is ideal for distorted waveforms, because it delivers true RMS measurement. Furthermore, the device is self powered from the 4 to 20 mA loop. Each phase has LEDs included, and these show when the unit has been able to connect to the right kind of power. The input of the device is either custom amperage or from 250 to 5,000 Amp. The accuracy is 1% either way. It comes with 8 foot of insulated leads as standard, from Rope CT to integrator. It also has 8 feet of output leads, which come in three sets of 600V twisted pairs for the three phase CT. The maximum voltage of the device on bare conductor is 600 V. It is CE and RoHS compliant, as well as being UL recognized and it comes with a 10 year warranty.
