4. معلومات السلامة
- حجم الإدخالtagه الحد: Do not exceed 30V DC input. Exceeding this limit can damage the module.
- Buck Module Operation: تأكد من مستوى الصوت المدخلtage is always at least 1V higher than the desired output voltage for proper operation. This is a step-down (buck) converter, it cannot boost voltage.
- No Reverse Polarity Protection: This module does not have reverse connection protection. Carefully observe input and output polarity (+/-) during wiring to prevent damage. Incorrect wiring will damage the module.
- تبديد الحرارة: While the metal case acts as a heat sink, ensure adequate ventilation, especially when operating at higher currents or in enclosed spaces.
- السلامة الكهربائية: Always disconnect power before making or changing any connections. Handle with care to avoid static discharge.

6. الإعداد والأسلاك
Follow these steps for proper setup and wiring of the module:
- تجهيز الاتصالات: Ensure all power sources are disconnected before wiring. Use appropriate gauge wires for your current requirements.
- اتصال الإدخال: Connect your DC input power source to the terminals labeled في+ (positive) and في- (negative). Double-check polarity.
- اتصال الإخراج: Connect your load or device to the terminals labeled خارج + (positive) and خارج- (negative). Double-check polarity.
- الفحص الأولي: Before applying power, visually inspect all connections to ensure they are secure and correctly polarized.
Note: The module does not include reverse polarity protection. Incorrect wiring will cause damage.
7. تعليمات التشغيل
Once wired, follow these steps to operate the buck converter:
- تطبيق طاقة الإدخال: Connect your DC input power source. The red LED voltmeter display will illuminate.
- شاشة حجم الصوتtage: The voltmeter will initially display either the input or output voltage. A short press of the button located below the digital tube will switch between displaying the input voltage (indicated by the 'IN' LED) and the output voltage (indicated by the 'OUT' LED).
- ضبط مستوى الصوت الناتجtage: Use a small screwdriver to carefully turn the potentiometer (labeled 'ADJ' or similar, typically a blue square component with a screw) to adjust the output voltagهـ. أدر باتجاه عقارب الساعة لزيادة الصوتtage, counter-clockwise to decrease. Monitor the output voltage on the LED display while adjusting.
- تحقق من المخرجات: بمجرد وصول حجم الإخراج المطلوبtage is set, you can connect your load.
المجلدtage display is factory calibrated and does not require additional calibration.
8. الصيانة
The DROK DC-DC Buck Converter Module is designed for reliable operation with minimal maintenance. Follow these guidelines:
- حافظ على نظافة: Ensure the module is free from dust, dirt, and moisture. Use a soft, dry cloth for cleaning.
- تهوية: Maintain good airflow around the module, especially during continuous high-current operation, to prevent overheating.
- فحص الاتصالات: قم بإجراء فحص دوري لجميع توصيلات الأسلاك للتأكد من إحكامها ووجود علامات التآكل أو التآكل.
- تجنب الصدمة الجسدية: Protect the module from drops or impacts that could damage internal components.
