Scope of application

The KT14 series cam controller is suitable for circuits with AC 50Hz and voltage up to 380V, mainly used for starting and reversing AC motors of cranes. This control has a reversible symmetrical circuit, suitable for the translation mechanism and lifting mechanism of cranes, and can also be used for starting, reversing, and adjusting motors of the same type.  

KT14 series AC cam controller model and its meaning


Main technical parameters
The KT14 cam controller is divided into:
The KT14-25J/1 and KT14-60J/1 controllers are used to control a three-phase wound induction motor;
The KT14-25J/2 and KT14-60J/2 controllers are used to simultaneously control two three-phase wound induction motors;
The KT14-25J/3 controller is used to control a three-phase squirrel cage induction motor;
The KT14-25J/4 controller is used to simultaneously control two three-phase wound induction motors (without stator circuit contacts).  

2. Main technical parameters of KT14 (see table)



Note: 1. Rated current refers to the contact parameters of a specified sub circuit. 2. The maximum control power refers to the JZR2 series motor, and for YZR and other series motors, the model can be selected based on the stator and rotor currents of the motor. 3. The mechanical lifespan of the controller shall not exceed 150 × 104 times at an operating frequency of 600 times/h. 4. The operating force of the controller shall not be less than 49N (5kg force).
