About the product
Gozuk Soft starter application scope
It is used for the smooth soft start of slip ring motor, rated voltage of 380V ~ 15KV
Standards adopted
Low voltage whole set switches and controllers
GB/T14048.1-2000 IEC60947-1:1999
GB7251.1-1997 IEC439-1:1992
Automatic liquid resistor starting, speed regulation and compensating controller Q/FZR1-2003
Soft starter working principles
A special liquid resistor is connected in series to the rotor circuit of slip ring motor; the liquid resistor get to work when the motor starts and its resistance gradually decrease during the preset time, so as the motor can start smoothly and accelerate eventually at minimal rated current and maximum torque. After start process is completed, the rotor circuit is shorted by the contactor. Its low starting current results in no impact on motors, load and power system as well as in no harmonic to affect the power system.
No maintenance is needed for the soft starters as automatic water filling system controlled by electrolyte level sensor and PLC can automatically fill the electrolyte tank with required amount of water when necessary.(optional)
Gozuk Soft starter main technical parameters
Initial start current Iq≤1.3In
Start time(s) 10~60, preset, adjustable on site
Start attempts(times): continually (ambient temperature 25℃)
Normal working temperature of liquid resistor:0-70℃
Protection level IP20,IP30
