Possible to follow many electrical parameter on digital transmission line via the NPM 250 series. 30 different parameters can be shown by three digitized four LED screens.
Via the basic front panel consisting of three buttons various electrical parameters are followed. This type energy analyzers can communicate with other devices and central work station by RS 485 output.
NPM 250 devices are compositional type of devices like voltmeters, ampere meters, cos & meters, watt meters, var meters, frequency meters. Thanks to this specification, analyzer has profits in respects to place, cable and device costs.
