Inverter & Soft-Starter — 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.
