NPM Power Analyzer

The main advantages of Asset NPM Power Analyzer are listed below:

  • Modbus-RTU, Modbus-TCP, Lon-Works, Profibus-DP communication alternatives
  • 72x72 mm panel and rail mounting models as well as the standard size dimensions (96x96)

NPM Power Analyzer (RS485) is used for basic power parameters of current, voltage, power, power factor, frequency etc. to measure electricity and energy parameters in distribution panels. Parameters can be monitored easily in low-light environments with their large size dimension seven segments LED display, even from a distance. 

As well as displayed on its screen, the measured parameters can be transferred to energy management systems and SCADA over various communication interfaces. Supported communication interface and protocols of the NPM Power Analyzer (RS485) are; RS485 Modbus-RTU, Ethernet Modbus-TCP, Profibus and Lon-Works.

The built-in Ethernet version of the device with Modbus-TCP/IP protocol has also the version of web server inside. It is possible to remotely connect using an internet browser without any management program and real time/historical measurements can be monitored.

NPM Power Analyzer (RS485) ensures the connection through industrial PLC devices by providing additional analog outputs or pulse outputs for energy consumptions to communication outputs.

NPM Power Analyzer (RS485) which has digital input optional models allows you to follow energy consumed on grid and generator separately. A reference cable taken from your generators will be connected to the tariff input of the analyzer to perceive start of the generator, then energy consumption of this period can be measured in different register in analyzer as generator consumption.

NPM series multimeters have models of 72x72 mm, 96x96 mm suitable for panel mounting and rail mounting. By this way they can be easily used in a lot of type applications.
