Product Description

I. Overview

GE VME7865RC is a powerful device with excellent performance.

Essentially, it is a single-board computer (SBC) based on the Pentium M processor, adopting a single-slot, passively cooled VME Eurocard form factor. This design endows it with excellent heat dissipation performance, enabling it to maintain a stable working state during long-term high-load operation and providing a solid hardware foundation for complex industrial control tasks. Its design concept is closely aligned with the actual needs of industrial automation, dedicated to providing efficient and reliable control solutions for various industrial systems, helping enterprises improve production efficiency and ensuring the stability and accuracy of the production process. Whether in large-scale industrial production lines or professional equipment with extremely high control accuracy requirements, GE VME7865RC can give full play to its advantages and become a core force in the industrial control link.

II. Technical Parameters

Electrical Parameters
Power Input: It shows good compatibility in terms of power input, supporting both AC and DC power types. The AC power input range is 110-240V AC with a frequency of 50/60Hz, which can adapt to the mains standards in different regions; the common DC power input range is 24-110V DC, meeting the needs of some specific DC power supply scenarios. This flexible power input design ensures that the device can stably obtain electrical energy, start normally and run continuously in complex and changing industrial sites.

Excitation Output (if involved): Since this module may be related to applications such as motor control, its excitation output capability can be configured according to different motor models and capacities. For common cases, the maximum excitation current can reach several thousand amperes, and the maximum excitation voltage can reach several hundred volts. Such a strong excitation output capability is sufficient to meet the excitation needs of synchronous motors of different power levels, ensuring that the motors can operate normally under various working conditions.

Power Consumption: It performs well in power consumption control. Under normal working conditions, the power consumption is usually maintained at a low level, generally not exceeding 500W. The low-power characteristic not only helps enterprises reduce energy costs and long-term operating expenses but also effectively reduces the heat generated during the operation of the device, lowers the risk of equipment failure due to overheating, and significantly improves the stability and service life of the device.

Control Parameters
Regulation Accuracy: It has extremely high voltage regulation accuracy, with an error usually not exceeding ±0.5%. This means that when controlling the terminal voltage of the synchronous motor, extremely precise regulation can be achieved, ensuring that the motor output voltage is always maintained within a stable range. Stable voltage output is crucial for the normal operation of the motor, which can effectively reduce the adverse impact of voltage fluctuations on the motor and the entire power system, and improve the operation quality and reliability of the system.

Response Time: It responds extremely quickly to changes in grid voltage and load, with a response time generally within tens of milliseconds. When the grid voltage fluctuates or the load changes suddenly, the module can respond in a very short time, quickly adjust the excitation current, enabling the motor to adapt to the changes in time and maintain stable operation. This fast response capability plays a key role in improving the dynamic stability of the power system and can effectively avoid equipment failures or production interruptions caused by slow system response.

Control Modes: To meet diverse industrial application needs, it supports multiple flexible control modes, including constant voltage control, constant excitation current control, constant reactive power control, etc. Users can freely choose the most suitable control mode according to the specific working conditions and control requirements in the actual production process. For example, in scenarios where it is necessary to keep the motor output voltage constant, constant voltage control can be selected; in cases where there are strict requirements for the motor excitation current, constant excitation current control is more applicable. This rich selection of control modes greatly improves the versatility and adaptability of the device, enabling it to better meet the personalized needs of different industrial users.

Environmental Parameters
Operating Temperature: It has a wide operating temperature range, usually from -10℃ to +55℃. This endows it with excellent environmental temperature adaptability. Whether in cold northern winters, hot southern summers, outdoor industrial facilities, or indoor production workshops, it can work normally, continuously and stably provide excitation control services for synchronous motors, and ensure that industrial production is not disturbed by changes in environmental temperature.

Relative Humidity: It can operate stably in an environment with a relative humidity of 5%-95% (non-condensing). The inside of the module adopts advanced moisture-proof technology and sealing design, effectively preventing humid air from eroding the internal precision circuits. This feature makes it particularly suitable for humid working environments, such as hydropower stations, factories near the sea, and some industrial workshops with high humidity. It can operate reliably in these environments, avoiding circuit short circuits, corrosion, and other faults caused by humidity, and ensuring the normal operation and service life of the device.

Anti-vibration Performance: It performs excellently in anti-vibration, capable of withstanding vibrations with a frequency of 10-150Hz and an acceleration of 0.5g. In industrial production, many devices generate varying degrees of vibration during operation, such as motor operation and reciprocating movement of mechanical equipment. GE VMIVME-017807-414001, with its excellent anti-vibration performance, can still maintain normal working performance in such vibration environments, without problems such as data loss and control failure due to vibration, ensuring the reliability of excitation control and providing strong guarantee for the continuity of industrial production.

III. Functional Features

Precise Excitation Regulation Function
Real-time Monitoring and Precise Regulation: GE VME7865RC adopts advanced digital control algorithms, which can monitor various operating parameters of the synchronous motor in real-time and accurately, including key indicators such as terminal voltage, excitation current, and reactive power. Based on these real-time monitoring data, the module can quickly analyze and judge, and effectively control the operating state of the synchronous motor by precisely adjusting the excitation current. When the grid voltage fluctuates or the load changes, the system can respond in a very short time, automatically adjust the excitation output, ensure that the motor terminal voltage is always stable, thereby maintaining the normal operation of the motor and ensuring the stability of the power system. For example, in the power system, when the power load suddenly increases, causing the grid voltage to drop, the module can immediately sense the voltage change, quickly increase the excitation current, raise the output voltage of the motor, restore the grid voltage to the normal level, and avoid affecting the normal operation of other electrical equipment due to low voltage.

Strong Reactive Power Regulation Capability: It has a strong reactive power regulation function, which can automatically and accurately adjust the reactive output of the synchronous motor according to the real-time reactive demand of the power grid. By optimizing the reactive power output of the motor, the reactive power balance of the power grid is achieved, which is of great significance for improving the power factor of the power grid. A high power factor can effectively reduce the loss of electrical energy during transmission, improve the energy utilization efficiency of the power system, and reduce the electricity cost of enterprises. At the same time, good reactive power regulation capability also helps to improve the voltage quality of the power grid and enhance the stability and reliability of the power system. In practical applications, the module can monitor the changes in the reactive power of the power grid in real-time. When it is found that the reactive power of the power grid is insufficient, it automatically increases the reactive output of the synchronous motor to supplement the reactive power of the power grid; conversely, when the reactive power of the power grid is excessive, it reduces the reactive output of the motor to maintain the reactive power balance of the power grid.

Comprehensive Protection Functions
Comprehensive Fault Protection Mechanism: It has a comprehensive and complete protection function system, covering over-excitation protection, under-excitation protection, over-voltage protection, over-current protection, loss of excitation protection, and other aspects. These protection functions can timely and accurately monitor and judge various abnormal situations that may occur during the operation of the synchronous motor and excitation system. Once an abnormality is detected, the protection function will act quickly and take corresponding measures, such as immediately cutting off the excitation circuit to prevent the fault from expanding, and sending a clear and definite alarm signal to notify the operator for timely handling. For example, when the over-excitation protection function detects that the excitation current of the motor exceeds the set safety threshold, it will immediately trigger the protection action, quickly cut off the excitation circuit, avoid damage to the motor due to over-excitation, effectively protect the safety of the motor and equipment, and reduce the risk of production interruption caused by equipment failure.

Excitation Winding Overheat Protection: It is specially equipped with an excitation winding overheat protection function, which monitors the temperature change of the excitation winding in real-time through a high-precision temperature sensor. When it is detected that the temperature of the excitation winding exceeds the pre-set safety value, the system will immediately start overheat protection measures, such as automatically reducing the excitation current to reduce the heat generation of the winding, or directly shutting down when necessary to avoid the excitation winding being burned due to overheating. This targeted overheat protection function can effectively extend the service life of the excitation winding, improve the reliability and stability of the device, and ensure that the excitation system is always in a safe and reliable working state during long-term operation.
