Power Meter PCE-ND20

The PCE-ND20 built-in power meter measures 3-phase all network parameters. Power, voltage, and power measurements are no problem for the PCE-ND20 built-in power meter. The current measurement can be done with the built-in power measuring device 3-phase and directly. However, it is also possible to measure high currents by means of transducers using the built-in power meter PCE-ND20. The voltage measurement takes place directly up to 480 V (phase to phase). The PCE-ND20 built-in power meter is only suitable for operation in 3-phase networks. All measured parameters are shown by the PCE-ND20 built-in power meter on the large, illuminated display. The user can scroll through the parameters via the front-panel keys and make all relevant settings for measurements with the built-in power meter. The voltage supply to the display is via a separate connection of the power indicator. The PCE-ND20 built-in power meter has an alarm relay which can be set freely by the user. In addition, the power meter has an analog, programmable 4 … 20-mA output. Via the Modbus RTU interface, all measured parameters can be integrated into the Modbus network by the power meter. The installed pulse output can be used to connect the PCE-ND20 built-in power meter to a separate energy meter / current meter. The front of the PCE-ND20 built-in power meter is protected to IP67. The PCE-ND20 built-in power meter is installed in switchboards. The cut-out is 92 x 92 mm / 3.6 x 3.6 in. The dimensions of the front of the built-in power meter are 96 x 96 mm / 3.8 x 3.8 in.
