TP-DK5 series transformers are used in the 50-60HZ ac circuit of input voltage less than 660V and output voltage less than 230V as machine equipment in various area for controlling the power of electrical equipment , lighting and Signal lamp. This series transformer is adopted in Germany technic and made improvement on the base of TP-DK3 model. It improve in advanced terminal block which can be connected to the coilframework together and increasethe wire compression so as to heighten protection grade to IP2LX to avoid touching circuit. It use IT end sleeves to increase fastness and reliability ofthe wire connection. This series transformer is adopted in weld of gas protection argon arc so as to be whole. The soleplate is moulding in one time to be more accurate and extract in the installation dimension. This series transformer is much improved in quality and shape. It conforms to GB5226，JB/T5555-201，VDE0550-1-3，IEC204-1，IEC-439 and gets CE approval.

TP-DK5 series engine bed control transformer technology characteristic

primary secondary circles the system separately, when secondary when a winding, it shoulders the transformer completely the rated capacity, when secondary like has at the same time the control, the illumination and the indicating lamp winding, presses various windings capacity assignment to circle the system separately, to simplex winding, and has intermediate tap's transformer its each intermediate tap capacity, is smaller than transformer's rated capacity, only then the overvoltage out-port may shoulder the rated capacity.
