Comprising the Danisense DS600 current sense transducer paired with the LMG600 power analyser from ZES ZIMMER, the system is already being used by renowned German standards organization, VDE, to calibrate and certify DC meters used in EV charging stations.
ZES ZIMMER’s LMG600 series power analysers provide DC measurement across a current input range of 500μA – 32A rms.
But EV charging stations supplying hundreds of kilowatts and other applications such as DC micro grids require currents in the hundreds of amps.
Danisense current transducers enable the system to measure up to 2000A rms (3000A peak or DC) and even higher.
DC meter accuracy is especially important, since customers will be charged on how much they use, and stability over temperature and other environmental factors is also important.
