CHINT NJR2-D Soft-Starter dual-CPU control technology,
NJR2-D series soft-starter is core on advance dual-CPU control technology.
furthermore It controls SCR module, realizes soft starting & stopping of three-phase AC induction motor,
and has wide range of protectionfunctions e.g. overload, input phase failure,
in addition to output phase failure, load short-circuit, starting limiting overtime,over-voltage, and under-voltage.
afterward NJR2-D series soft-starter requires external bypass contactorwith voltage range of 380V,
for example power specifications for 7.5KW to 500KW; has characteristics of good load adaptability,stable and reliable operation,
and widely use in electrical drive equipment in the fields of metallurgy,
in the same way petroleum,fire, mining, water supply, municipal, food, cement and petrochemical.
in conclusion It is an ideal update product of traditionalstar – delta starter, and self-coupling voltage starting.
Standard: GB 14048.6 IEC 60947-4-2.
