The development plan for the pump control mainboard PCBA includes a waterproof design for the pump driver circuit board and customizable circuit boards.
The pump control mainboard PCBA solution is a high-current motor drive solution with extremely stringent requirements for motor drive power, waterproof reliability, overload protection, and control logic in the fields of industrial control, agricultural irrigation, and water treatment. Its core is an industrial-grade MCU with high reliability, ADC, and advanced timers, which collects sensor signals such as water pressure, flow, and liquid level, and uses PWM or relays to precisely control the start, stop, and speed of single-phase/three-phase pump motors. It also integrates overcurrent, overvoltage, phase loss, and dry running protection functions to achieve intelligent features such as constant pressure water supply, liquid level control, and timed irrigation, ensuring long-term stable operation of the system.
As a PCBA solution provider with rich safety design and strict quality control experience in the field of industrial motor drives and harsh environment applications, we fully understand your extreme pursuit of driving capability, waterproof rating, protective measures, and long-term reliability. We can provide you with a complete solution for the pump control board PCBA that is powerful in driving, comprehensive in protection, waterproof and durable, and stable and reliable.
