Direct-current Static Watt-hour Meter AEM11-PS

etthv

 

AEM11-PS is a direct-current static watt-hour meter for indirect connection designed to measure electric energy in direct-current traction framework. It is connected into the measurement circuit through the external galvanically devided direct-current converters of voltage and current. The meter conforms the STN EN 50463: Traction applications norm. Measurement of energy on locomotive vehicles.
