Feature of product

The explosion-proof soft starter is used for torque control soft start and soft stop of three-phase squirrel cage asynchronous motor. It is supplied with machine and motor

The soft start and deceleration functions of the protection function, as well as the function of communicating with the control system, its high performance algorithm improves

Equipment availability, security, and ease of use have played a significant role;

The soft starter has an Altistart torque control function that linearly controls the torque supplied to the motor during acceleration and deceleration periods.

Easy to adjust the ramp and starting torque, the wide frequency is suitable for the engine power supply, it can be connected to each motor triangle

The windings are connected in series;

Built-in motor thermal protection, PTC direct thermal protection, start time detection, motor preheating function, underrun in continuous operation and

Overcurrent protection;

The operator panel can be used to modify programming, adjustment or monitoring so that the device can be adjusted and optimized to suit different users.

Claim;

The normal start and heavy load start can be selected according to the load characteristics, and the starting parameters can be set by themselves;

The outer casing is welded by steel plate and the surface is electrostatically sprayed with high voltage.
