Epcos sense transformer measures 40A ac
Wednesday 30 September 2009
Epcos has extended its product range by four current sense transformers: the new series was developed on the basis of an EE12.6 ferrite core and is suitable for measuring alternating currents of up to 40A.
The primary winding consists of an external yoke. The DC resistance of the primary winding is 0.28mΩ for all types, the rated current is 40A.
The transformers are available with inductances of between 1.4 and 22.4µH and secondary-side DC resistances of between 400 and 2500mΩ.
Their turns ratios are between 1:50 and 1:200 and they have a test voltage of 1500 V AC. All new current sense transformers are compatible with existing designs based on EE12.6 cores.
