PFSA140通过向PFSK180馈送62.5kHz的原始交流电开始，PFSK180执行AC-DC转换和一些滤波。

PFSK181反过来调节和供给转换和滤波后的电流到测量辊。此时，水流可能会分流在一定程度上偏离期望的恒定电流。此分歧的信息被发送回并被PFSK187用于调节PFSA140。

除此之外，PFSK187还具有让调节器快速找到工作范围的功能。这是通过测量馈电的电压和电流来实现的

使用模拟PFSA140电压和电流输入从PFSA140到DTU实际调节在FPGA和下面列出的不同组件中执行有助于促进这一点

The PFSA140 starts by feeding 62.5kHz of raw AC power to the PFSK180, which performs AC-DC conversion and some filtering.

The PFSK181 in turn regulates and supplies the converted and filtered current to the measuring roller. At this point, the water flow may diverge somewhat from the desired constant current. This diverging information is sent back and used by PFSK187 to regulate PFSA140.

In addition, the PFSK187 allows the regulator to quickly find its operating range. This is done by measuring the voltage and current being fed

Using analog PFSA140 voltage and current inputs to actually regulate from PFSA140 to DTU is performed in the FPGA and the different components listed below to help facilitate this
