KWH-MARSEN

National Registry: No 58638-20 (extended until 01.04.2030)

Calibration interval: 3 years

Accuracy class: 0.5 / 1

Purpose

Accuracy class with respect to energy measurements 0.5 or 1

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 from 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
	display 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)у;
	display of measured values on the built-in display or external device (e.g. laptop) via USB
