NJR2-D Soft-Starter

NJR2-D series soft-starter is cored on advanced dual-

CPU   control  technology.  It  controls  SCR  module ,

realizes  soft  starting  &  stopping  of  three  –  phase

AC induction motor, and has wide range of protection

functions  e.g.  overload,  input  phase failure,  output

phase  failure,   load   short – circuit,  starting  limiting

overtime, ove r- voltage, and  unde r- voltage.

NJR2-D series soft-starter  requires  external  bypass

contactor with  voltage  range  of  380V,  power

specifications for 7.5KW to 500KW; has characteristics

of good load adaptability,stable and reliable operation,

and widely used in  electrical  drive  equipment  in  the

fields of metallurgy, petroleum,fire, mining, water supply,

municipal,food, cement and petrochemical. It is an ideal

updated product  of  traditionalstar – delta  starter ,  and

self-coupling voltage starting.
