- Anti-Reverse Connection Protection: Prevents damage if input polarity is reversed.
- Anti-Reverse Flow Protection: Protects the input power source from current flowing back from the output.
- تحت المجلدtagالحماية الإلكترونية (LVP): Automatically cuts off output if the input voltage drops below a safe threshold. Increase input voltage to resolve.
- زيادة الحجمtagالحماية الإلكترونية (OVP): Shuts down output if the output voltagيتجاوز e الحد المحدد.
- الحماية من التيار الزائد (OCP): Disables output if the output current surpasses the set limit.
- Over-Temperature Protection (OTP): Activates if the module's internal temperature becomes too high, reducing power or shutting down to prevent damage.
- Over-Power Protection (OPP): Limits output power to prevent exceeding the module's maximum capacity.
تأكد دائمًا من أن مستوى صوت الإدخالtage and current are within the specified ranges to avoid triggering protection mechanisms or damaging the module.
8. استكشاف الأخطاء وإصلاحها
- No Output/Low Output Voltage: Check input power supply for sufficient voltage and current. Verify output connections and load. Ensure LVP is not active (increase input voltage if necessary).
- ارتفاع درجة حرارة الوحدة: Ensure adequate ventilation. Consider installing a 30mm 5V fan to the dedicated port if operating at higher loads or in warm environments.
- مشاكل العرض: Check power connections. If the display is unresponsive, try power cycling the module.
- Protection Activated: If any protection (OVP, OCP, OTP, OPP) is triggered, identify and resolve the underlying cause (e.g., reduce load, check for short circuits, ensure proper cooling) before resuming operation.
