Detailed CHINT Series NJR1 Digital Soft Starting Controller Description
Applicable scope:
Series NJR1 digital soft starting controllers Controlled automatically by 16Bit CPU.
Series NJR1 soft starting controllers are widely used in motor transmission
equipment of all industry fields, petroleum, such as metallurgy, fire
fighting, mine and petrifaction covering 7. It
can protect the motor from overload, over voltage, defect phase, under voltage,
overheating and so on.5 - 500kW asynchronous motors.
We have also developed one - hauling two, one - hauling three and one - hauling
multiple set motor soft starting control cabinets; one common and one
reserve, two common and one reserve fully automatic switching soft starting
control cabinets; and duplicate supply automatic switching, one common and
one reserve fully automatic switching fire fighting special control cabinets.
It is the ideal last generation product to replace traditional star - delta
starting, reactor starting and auto - negative boosting starting.
The product performance conforms to the related stipulation of GB 14048.6 - 98.
