KWH-MARSEN

DC KWh meter is especially designed for DC energy monitoring in DC electric railway systems or for other transport DC power applications.

ACCURACY CLASSES: 0.5 / 1

NATIONAL REGISTRY N: 58638-14

DESCRIPTION:

Rated current: 5 to 7500 A
Rated voltage: 100 to 3000 V

Advantages (over conventional instruments of the same type):

  • Basic electric energy input/output values are recorded in the form of profiles (current, voltage, power, energy, traction line voltage) and displayed as tables or graphs
  • Selectable averaging interval (1 s to 30 min)
  • Logging capacity of input/output values:
  • 1 day (min) – at 1 s interval
  • 3 years (min) – at 30 min interval
  • Accepts signals from two different current sensors via its two galvanically isolated (with an external isolating transformer) current measurement channels: e.g. from locomotive motor and on-board apparatus, or from on-board lighting and auxiliaries
  • Energy values are recorded for both directions
  • Displaying cumulative values for energy of different types
  • Readings (currents, powers, mains voltage, etc.) are continuously recorded in user-specified intervals
  • Automatic event log recording
  • Multilevel password protection
  • Data exchange with external devices (PC) via Ethernet, RS-485, RS-232, or USB (depending on design version)
  • Wireless data exchange (built-in RF module)
  • Display of measured values on the built-in display or external device (e.g. laptop) via USB
