适用于柜体安装式 ACS880-307 +A018 二极管供电单元，该单元是 ACS880 多传动
系统的一部分。
介绍二极管供电单元如何运行。还包含有关二极管供电单元硬件的描述。这些信息适用于 ACS880-307 +A018 二极管供电单元。
二极管供电单元的核心是二极管- 晶闸管整流桥。该桥可将三相交流电整为直流电，向传动的中间直流回路。中间直流回路为逆变器供电。可将一个逆变器单元（单传动）或多个逆变器单元（多传动）连接到中间电路。交流电抗器可使传动供电网络中的电流波形以及直流回路中的电压变得平滑。
普通二极管- 二极管整流桥与可控二极管- 晶闸管整流桥之间的主要区别在于可控性。二极管导通不可控，但可以控制晶闸导通。通过控制晶闸管，用户无需在供电单元或逆变器单元中增加额外的充电电路，即可限制上电时传动的交流电流。
Glossary
Process station:
This term is used to describe AC800F controllers (field controllers) and rack-mounted controllers. A process station can be designed to be redundant
configuration and non-redundant configuration.
AC800F :
This term is used to describe the AC800F Field Controller type of process station. A redundant process station consists of 2
AC800F controller.
Rack mounted process station:
This term is used to describe a rack-mounted type of process station. A redundant process station contains 2 rack-mounted CPUs.
This term is used to describe a single, non-redundant process station.
In the investment of modern automation system, due to the hardware equipment department
It only takes up less cost in the whole system, then write engineering applications
The cost of software becomes increasingly important. Generally speaking, a self
The engineering application software cost of the automation project accounts for about the entire project.
About 50%, it is not difficult to see that the migration of cost structure creates a lot of innovation for users.
Create an opportunity to optimize project investment, therefore, it is necessary to start from engineering programming
Think about lowering costs in the first place!
This is what we developed the Freelance 800F system for:
Keeping hardware prices consistent with those of programmable logic controllers
In this way, cost efficiency can be improved by reducing user engineering costs.
How the Freelance 800F process control system
