The CR1 series motor soft starter (hereinafter referred to as the soft starter) is mainly suitable for controlling and protecting the starting, running, and stopping of squirrel cage motors. Because when the motor is directly started, the starting current can reach 7-10 times the rated current of the motor, which has a significant impact on the power grid and can affect the service life of mechanical equipment, even causing serious malfunctions and significant economic losses. The use of CR1 series soft starters can avoid these problems, and its performance has reached the advanced level of similar products internationally.
The CR1 series soft starter adopts single-chip microcomputer control technology, which controls the output voltage and reduces the starting current by detecting the current and power factor.
(1) The CR1 series motor soft starter has a soft start function, which can reduce the starting current and torque of the motor, and minimize the torque impact generated during starting;
(2) Equipped with soft parking function, it can gradually reduce the terminal voltage of the motor, avoiding damage to the equipment caused by sudden parking;
(3) It has protection function and can protect against faults such as overload, three-phase imbalance, phase failure, peak overcurrent during starting, current limiting starting timeout, radiator overheating, etc.
Rated working current: 30A~900A;
Rated working voltage: 400V, 50Hz;
Soft start time, soft stop time, base voltage, trip level, and current limiting factor can be set;
The CR1 series motor soft starter complies with IEC60947-4-2 and GB14048.6 standards and has obtained the national mandatory product certification "CCC" mark.
