The CT256 series open-type current transformer is a series of miniaturized open-type products designed based on the improvement of current instrument and equipment software processing capabilities. Due to the increase in current monitoring equipment, a small and easy-to-install open-type current transformer is needed. The CT256 series products came into being and are increasingly widely used. Many instruments also use such products, and combined with the correction of the transformer output curve by the instrument software, more accurate results are obtained. It is a low-cost solution.
This type of product generally uses small current signal output or voltage signal output to maximize product accuracy and reduce hardware costs. Standard 5A or 1A current output products have poor load capacity. It is recommended to use wires with a cross-sectional area of not less than 2.5mm2. When outputting current signals, the secondary circuit of the transformer needs to be connected before installation to avoid the risk of electric shock due to high voltage generated by the open secondary circuit during installation. After installation, the transformer needs to be well fixed to the measured wire with nylon cable ties.
This series of products is designed with 6 specifications. Silicon steel core, nanocrystalline alloy core and ferrite core can be used according to needs to reduce costs as much as possible while ensuring application.
