PowerFlex 400 交流变频器安装简便，非常适合用于机械风扇和泵系统，同时它还具有大量的内置功能，可以与建筑系统进行无缝集成。PowerFlex 400 交流变频器为满足全球 OEM、承包商和最终用户对产品灵活性、节省空间和易用性的需求而设计。
• 在 380-480V 下，额定功率为2.2…250 kW/3.0…350 Hp，在 200-240V下，为 2.2…37 kW/3.0…50 Hp
• 集成 PID 控制器可以自动调节输出频率，从而保证过程变量的稳定性
• 三个可编程的跳转频率及带宽可以有效防止变频器长时间在共振速度下运转，从而避免可能出现的机械故障
• 可选的风扇/泵曲线为离心式风扇和泵负载提供了降电压模式
• 睡眠功能允许系统在需求低于预设水平时停止运行，并在需求升高时自动重启
• 对于需要无人操作的应用，上电启动功能可以让变频器在恢复电力中断后自动恢复运行。
• 可以通过灭火和冲洗输入端口连接至消防和人身安全系统
• 附属电机控制允许对附加直接启动电机进行分级运行，以满足系统需求
• 可以使用阻尼器输入来禁用变频器输出，直到获取需要的阻尼器位置，即使在采用有效运行命令的情况下也能如此.

Freelance 800F Process Control Stage
At the process control level, the Freelance 800F system can be controlled by
It consists of a number of process control stations connected to I/O units. you can choose this
Some process stations are in redundant mode (CPU redundancy, fieldbus module redundancy
redundant) or non-redundant mode. Modular pluggable input/output modules
Blocks are freely selected and used according to the type and number of system process signals.
