Product Introduction

Siemens Power Board C98043-A1601-L1 is a power board produced by Siemens, mainly used in industrial control systems. The following are its main functions and features:
Lower power required at startup
The motor power is proportional to the product of current and voltage. The power consumed by the motor directly started by the power frequency will be much higher than the power required for variable frequency starting. Using a frequency converter to start and stop the motor can effectively avoid surge problems and reduce the impact on the power grid.

Controllable acceleration function
The variable frequency speed regulation can start at zero speed and accelerate evenly according to the needs of the user. You can choose linear acceleration, S-shaped acceleration or automatic acceleration to reduce mechanical wear and loss and extend the life of mechanical parts and motors.

Adjustable running speed
The use of variable frequency speed regulation can optimize the process and quickly change the running speed according to the process. The speed change can be achieved through remote control PLC or other controllers.

Control the starting current of the motor
When the motor is directly started by the power frequency, it will generate 7 to 8 times the rated current of the motor, increase the electrical stress and heat of the motor winding, and reduce the life of the motor. Variable frequency speed regulation can start at zero speed and zero voltage, reducing current shock.

Reduce power line voltage fluctuations
When the motor is started at industrial frequency, the current increases sharply and the voltage also fluctuates greatly. Variable frequency speed regulation can effectively stabilize the voltage and reduce the voltage drop.

Low power consumption at startup
The power board requires less power at startup because the motor power is proportional to the product of current and voltage, and the power required for variable frequency starting is usually lower than that of motors directly started at industrial frequency.

Controllable acceleration function
Variable frequency speed regulation can start at zero speed and accelerate evenly according to user needs, and its acceleration curve can also be selected (such as linear acceleration, S-shaped acceleration or automatic acceleration), which helps to reduce mechanical wear and loss and extend the life of mechanical parts and motors.

Adjustable operating speed
Through variable frequency speed regulation, the process can be optimized, and the operating speed can be quickly changed according to the process. Speed ​​changes can also be achieved through remote PLC or other controllers.

Controlling the motor starting current
When the motor is started directly by the power frequency, it will generate 7 to 8 times the rated current of the motor, which will greatly increase the electrical stress of the motor winding and generate heat, thereby reducing the life of the motor. However, variable frequency speed regulation can start at zero speed and zero voltage (torque boost can also be appropriately added), thereby better protecting the motor.

Reduce power line voltage fluctuations
When the motor is started by the power frequency, the current increases sharply and the voltage also fluctuates greatly. The voltage drop depends on the power size of the starting motor and the capacity of the distribution network. Using a frequency converter to start and stop the motor can effectively reduce this voltage fluctuation.
