TQ50 - Split-core Current Transformer The very compact ELEQ TQ50 split-core current transformer is especially designed for connection to digital measurement systems. The accuracy of these current transformers results in highly accurate current measurements. All TQ50 current transformers are capable of supplying the specified burden at the end of the secondary leads. The TQ50 is easy to install; the top part can be removed entirely. The TQ50 is supplied with color coded secondary leads and correct closing of the current transformer is guaranteed by a distinct sound of a “click”. Two tie wraps are included for easy assembling the current transformer on the primary conductor.
