Split Core Transformers with High Ratio (mA)
This special type of current transformer with low secondary rated current is suitable to measure wide spectra of appliances and network loads up to 650A AC. Its biggest advantage is a simple installation which is possible even without disconnection of the load. Split-core CTs can be simply opened and clamped around the wire/line even under operation. Similar in function but mechanically different is the JCLA-2500 Clamp CT.
This CT is supported by our simple panel instruments SML 33, SML 133, SMM and SMN 33, DIN rail mountable PA 144 and SMC 144, and analyzers SMZ 133, SMV and SMVQ, SMP and SMPQ.
The JCLA-2500 clamps can be also ordered as a CT option for our portable power quality analysers. The input is also suitable to be connected toinput of various standard industrial PLCs and thus can be used in various other automatization tasks.
