变频恒压供水控制柜是整套变频恒压供水设备的技术和现实意义之一，因此是市场竞争的关键。变频控制柜的关键是调节设备的输出功率，降低功耗，使设备稳定运行，减少设备立即运行时大电流对电机的危害。同时，内置模拟量输入键（用于速度控制或反馈数据信号）、PID控制和泵切换控制用于恒压、通讯功能，宏功能（不同地点的不同主要参数设置）和两级速度。

Frequency conversion constant pressure water supply control cabinet is one of the technical and practical significance of the whole set of frequency conversion constant pressure water supply equipment, so the price is the key to market competition. The key of frequency conversion control cabinet is to adjust the output power of equipment, reduce power consumption, make the equipment operate stably and reduce the harm of large current to the motor when the equipment runs immediately. At the same time, the built-in analog input key (for speed control or feedback data signal), PID control and pump switching control are used for constant pressure, communication function, macro function (different main parameter settings in different places) and two-stage speed.

选择变频恒压供水设备时，应注意操作功能和设备，从控制柜的操作类型到二次设备，再到可以完成的功能

When selecting frequency conversion constant pressure water supply equipment, attention shall be paid to the operation functions and equipment, from the operation type of control cabinet to secondary equipment, and then to the functions that can be completed
