Product Introduction

Siemens Robincon unit control board a1a10000432.73m is a control board suitable for Siemens Robincon inverters, which has the characteristics of high precision. Its main functions include driving IGBT (insulated gate bipolar transistor) and detecting unit faults, such as unit voltage division and over-temperature. The working environment of the control board requires 20℃~26℃ at room temperature and 40%~65% humidity, and needs to avoid direct sunlight and electrostatic protection. When using high-voltage inverters at customer sites, attention should be paid to changes in temperature and humidity in the installation environment, and air conditioners or ventilation equipment and dehumidifiers should be turned on in time to prevent over-temperature or over-humidity operation. Clean the dust inside the inverter regularly to ensure that the cooling air path is unobstructed, and pay attention to electrostatic protection. Check whether the wiring terminals are tightened, ensure that each electrical circuit is correctly and reliably connected, and keep the relevant markings clear and complete.

High precision: This control board has the characteristics of high precision and is suitable for occasions that require precise control.

Strong adaptability: It is suitable for Siemens Robincon units, can work stably in the temperature range of 5-40°C, and adapt to different industrial environments.

High efficiency: With current vector control mode, it can provide efficient power conversion and utilization efficiency.

Durability: The PAM output voltage regulation method is adopted, combined with the structure of metal plates, which improves the durability and reliability of the control board.

Safety: Built-in multiple protection functions, such as unit voltage division and over-temperature detection, ensure the safety of equipment and operators.

Control function
The control method is current vector control, which helps to achieve precise control of the motor, such as speed regulation, torque control, etc. It can provide better performance. The operating state of the motor can be accurately adjusted according to actual needs to improve the operating efficiency and stability of the system.

Power supply related functions
In terms of the number of power supply phases, there are different applications of single-phase and three-phase. The rated voltage is three-phase AC525-690V (such as in some application scenarios), and the supply voltage is high voltage. The nature of DC power supply is current type, which is of great significance to the power management and energy conversion of the whole system, and helps to adapt to different power input conditions and ensure stable power supply to related equipment.

Motor adaptation
The power of the adapted motor varies in different scenarios, such as 5 - 40°C (kW) range and 6000kW. It can effectively control and manage the motor according to the motor requirements of different powers, so as to ensure the normal operation of the motor under different loads and working conditions.

Voltage regulation function
The output voltage regulation method includes PAM or PWM control. These adjustment methods help to accurately adjust the output voltage according to the actual working needs to meet different application scenarios and equipment operation requirements.

Drive IGBT: The unit control board is responsible for driving IGBT, which is one of its important functions. In the working process of the inverter, IGBT (insulated gate bipolar transistor) plays a key role. Through the drive of the control board, the effective control of IGBT can be achieved, thereby affecting the operating state of the entire inverter.

Detect unit fault
Unit voltage division detection: It can detect the unit voltage division situation to ensure that the voltage of each unit is within the normal range. If the voltage division is abnormal, it may affect the stability of the entire system, and the control board can detect this abnormality in time so that corresponding measures can be taken.

Overtemperature detection: Detect the temperature of the unit to prevent the unit from being damaged due to excessive temperature. In actual operation, the unit of the inverter will generate heat when working. When the heat dissipation conditions are poor or the workload is too large, overtemperature may occur. At this time, the overtemperature detection function of the control board can play a role, and timely alarms or protective measures can be taken to ensure the safe operation of the equipment.
