詳細介紹

VMVME-7807/VME-7807RCGE Fanuc嵌入式系統(tǒng)公司的先進單板計算機(SBC)。這些SBC基于Pentium®M架構(gòu)構(gòu)建,設計為適合單插槽、被動冷卻、VME歐洲卡外形,使其適用于各種嵌入式和工業(yè)應用。

 

主要特點:

 

內(nèi)存:支持高達1.5GBDDR SDRAM,其中1.0GB通過SODIMM連接,可選512MB焊接內(nèi)存。

 

視頻:包括用于前面板連接的內(nèi)置SVGA和用于后部I/O的數(shù)字視頻控制器,具有DVI-D雙頭顯示功能。

 

網(wǎng)絡:提供10/100 Mbit以太網(wǎng)和雙千兆以太網(wǎng),可在前面板或后I/O上連接。

 

存儲:通過后部I/O支持串行ATASATA)和Ultra IDE驅(qū)動器。

 

接口:具有串行端口(COM1)、鍵盤/鼠標端口和可選的P0,帶VITA 31.1接口,可增強連接。

其他功能:包括實時時鐘/日歷、前面板重置開關(guān)、微型揚聲器,并能夠運行Windows XPWindows 2000和各種Linux發(fā)行版等桌面操作系統(tǒng)。

 

這種功能組合使VMVME-7807/VME-7807RC成為緊湊型工業(yè)外形中需要可靠桌面級性能的應用程序的強大解決方案。

The modern energy storage system of lithium-ion batteries has been widely adopted in various applications due to its efficient and reliable performance. However, ensuring the safety and stability of the system requires strict monitoring of each battery unit to prevent battery imbalance, overcharging, deep discharge, or overheating. To achieve this goal, it is necessary to provide independent isolated power supply voltage control circuits for each battery unit or battery array.
For battery arrays with a nominal voltage of up to 48V, standard industrial DC/DC power converter modules that provide 500V or 1600V isolation barriers can usually be used. However, for systems that require higher power and are connected to AC power sources, the battery array voltage may reach 600-800V, which requires solutions with higher isolation barriers.
Low isolation capacitance enhances noise resistance
The P-DUKE medical power converter series has a 5kV isolation barrier, exceeding the conventional requirement of 4kV. In this project, MPD30-24S12 was selected, which can generate the necessary 12V/30W power voltage from the common 24V DC bus.
The input and output capacitance of a typical industrial 30W DC/DC power converter can reach 1500pF. If up to 200 converters are used in parallel, the total capacitance between the battery unit (connected to the AC grid through a charger) and the 24V bus may reach 300nF, resulting in an AC leakage current exceeding 20mA. A current exceeding 10mA may cause serious electric shock and accidents.
The input and output capacitance of MPD30-24S12 is only 20pF, so the total capacitance after 200 converters are connected in parallel is only 4nF, and the leakage current is less than 1mA. This low capacitance also avoids transient or any noise coupling from the AC/battery side converter to the sensitive communication signal of the central battery management system.
Through this solution, the requirements for 4kV isolation and low leakage current have been well met.
Communication and Power Solutions
For communication throughout the installation, the central BMS controller uses a WiFi router and is powered by a 25W 53V power supply via Ethernet. According to the final installation, the power supply voltage can be generated by a 230Vac main power supply or an internal 24Vdc bus. For 230Vac, TSD30 series converters can be used. It also offers a Din rail version for easy installation in the controller rack.
Successful cases have shown that the RCD30 series converter can generate a 53V voltage from the 24Vdc bus and adjust the output from 54V to 53V. It also comes with an integrated heat sink for easy cooling.
P-DUKE product application
The MPD30/MPD30W series is a series of 30W DC/DC power converters with enhanced 5000Vac isolation voltage, which meets the requirements of medical applications. This series has different input voltage ranges and provides single or dual output. This series complies with the 2MOPP standard, with an electrical clearance and creepage distance of 8 millimeters. This makes them suitable not only for medical devices, but also for other applications that require high isolation and extremely low input/output capacitance.
The TSD30 series is a ready to use AC/DC solution suitable for Din rail applications. Like the RCD30W series, it provides different output voltages and installation options for various applications.
