Серия DCflex

The DCflex current probe from Power Electronic Measurements Ltd is an easy to use, economical, clip-
around DC current probe.
It is suitable for measuring large dc currents of 2kA and greater.
The probe takes a single shot measurement of the DC current with a typical accuracy of ±1%.

Benefits and features:
thin, flexible, clip-around coil easy to insert in confined spaces
accuracy typically ±1%
intrinsically safe, galvanically isolated measurement
 battery powered with an integral display on the enclosure, thus no need for external scopes or meters

Application:
smelting plants
cathodic protection
hydro-generation
DC connection buses between large users
DC link (large inverter motor drives)
plating plants
verifying the performance of large dc shunts or hall effect transducers that are in-situ
