Power Indicator PCE-NR30IoT

The power indicator PCE-NR30 is able to measure currents directly up to 63 A AC. The power indicator can also be used with the aid of x / 1A or x / 5A current transformers. The power indicator measures network parameters of symmetrically and asymmetrically loaded single-phase 2-wire systems and three-phase 3 or 4-wire systems. The PCE-NR30 power indicator is also able to measure harmonics up to the 51st order. The power indicator impresses with its high accuracy class of 0.2s. Thus, the indicator meter is also suitable for demanding measurement and research tasks. The display always provides information about all network parameters and the maximum and minimum measured values ​​can be shown directly at the push of a button. Two adjustable alarm outputs round off the overall package of the power indicator. Optionally, the power indicator can be expanded by 4 x 4 … 20 mA or 0 … 10 V outputs via the PCE-S4AO module.

The power indicator is mounted on the top hat rail and is built according to EN62208. An RS485 and an Ethernet interface are available as standard. The interface is accessed via Modbus RTU or Modbus TCP. It is also possible to read out the power indicator via HTTP request or via FTP. The power indicator can be set using the buttons on the front or via the USB interface using the programming software.
