I. Overview and Application
 
 The BK, JBKJBK5 series single-phase control transformers are produced by our company over the years using selected materials and advanced technology. They can penetrate deep into the load center. They are mainly used for various machine tool signal indications, control buttons, and safety operation circuits with AC 50-60Hz and voltages not exceeding 1500V. The distribution of various input and output voltages, connection groups, and tap line group capacities of the product can all be carefully designed and manufactured according to customer requirements. They also offer additional advantages such as fire resistance, moisture resistance, safety, energy savings, and convenient maintenance.
