Rail mounted energy analysers with circuit breakers offer the following advantages:

  • Space savings with busbar mounting
  • Bidirectional energy measurement capability
  • Modbus-RTU communication
  • THD measurement
  • Grid/Generator tariffing option
  • Circuit breaker for use in prepaid systems (NDM50 Series)
  • 1 x 230V or 3 x 230/400 V
  • Safe usability with MID, RoHS, and CE certifications

It is ideal for users experiencing space constraints, particularly in electrical panels. Thanks to Modbus communication, it can also be used in system solutions.

It is highly suitable for use in locations with large energy infrastructure requiring high measurement points, such as residential buildings, shopping malls, and residences.

It is also suitable for use in locations requiring shared usage.

Rail-type circuit breaker energy analyzers, which can measure reactive energy in parallel with active energy, also enable the monitoring of possible compensation needs. With both import and export energy measurement capabilities, it allows monitoring of both consumed and generated energy. In addition to energy parameters, it can also measure current, voltage, power, and frequency.

THD measurement, one of the power quality parameters used especially in 3-phase measurements, is a great help. They are also used to monitor harmonics, which are the most important power quality problems.

With NDM50, it can operate on a prepaid system basis, allowing you to use only what you pay for, and it also allows you to cut off the energy supply to subscribers who do not pay their bills without having to go to their location.

The prepaid structure is generally used in buildings such as shopping malls, residences, and timeshares. This design frees the user from hassles such as bill due dates and encourages more planning. Prepaid amounts also allow the distribution company to purchase electricity at more affordable prices in a planned manner.
