Dishwasher Power Control Board
High-Power Intelligent Drive Integrated Board · Core Control & High-Voltage Drive All-in-One
- Deeply adapted for complex loads including wash pump, drain pump, and high-power heating element
- Professional-grade conformal coating treatment effectively resists high-temperature and high-humidity environments
- Mature isolated switching power supply technology ensures strong/weak electrical isolation for enhanced safety
- Multiple detection and intelligent protection against pump stall, dry heating, and other abnormal conditions
Key Advantages
Deeply engineered for the unique operating conditions and demanding electronic control requirements of dishwashers, with quality assured at every step.
Dishwasher-Specific Deep Adaptation
The power supply and logic control of this board have been precisely tuned to effectively match the complex electrical loads unique to dishwashers, including the wash pump, drain pump, circulation pump, and the high-power bottom heating element.
Long-Term Durability in Harsh Conditions
The internal environment of a dishwasher is perpetually hot and humid. Every board undergoes professional-grade conformal coating (insulating moisture-proof coating) treatment before shipment, effectively preventing short circuits caused by condensation and component corrosion, significantly extending service life.
Efficient & Safe Power Delivery
Utilizes mature isolated switching power supply technology, providing reliable isolation between high and low voltage. Onboard large-capacity filter capacitors and surge suppression devices ensure stable power delivery to the MCU and sensors even during voltage fluctuations.
Multi-Layer Intelligent Safety Protection
Integrates multiple detection and protection mechanisms. In the event of pump stall, heating element dry-burn, circuit overcurrent, or overload, the protection circuit rapidly cuts off the main power supply, safeguarding core internal components from damage.
Professional-Grade Factory Testing
Every single board undergoes high/low-temperature aging and full-load burn-in testing before shipment, ensuring that the performance of the core control chip and power devices remains stable and reliable under extreme conditions.
