PriceList for Toroidal Common Mode Choke - SANHE EI57 Low Frequency 220V 110V Power Lead AC DC Transformer – Sanhe
PriceList for Toroidal Common Mode Choke - SANHE EI57 Low Frequency 220V 110V Power Lead AC DC Transformer – Sanhe Detail:
Introduction
The EI57 transformer is mainly used for industrial water level measurement equipment. It supplies power for relay of the equipment and can output four groups of working voltages at the same time under the mode of two input voltage. Since the equipment has high requirements on the accuracy of the working voltage and requires a sufficient safety distance from the primary and secondary, a split BOBBIN is used to process the primary and secondary windings respectively. When the transformer receives a control command, it can accurately drive relay to work.
