AI Overview
China-manufactured Constant Pressure AC Drives (VFDs) are specialized variable frequency drives designed to maintain stable water pressure, primarily for pumps, by automatically adjusting motor speed based on demand. They typically feature built-in PID controllers, multi-pump control, and energy-saving modes, with many suppliers offering IP54 or IP65-rated, compact "backpack" designs.
