4. የደህንነት መረጃ
- ግብዓት Voltagሠ ወሰን ፦ Do not exceed 30V DC input. Exceeding this limit can damage the module.
- Buck Module Operation: የግቤት ጥራዝ ያረጋግጡtage 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.
- የሙቀት መበታተን; While the metal case acts as a heat sink, ensure adequate ventilation, especially when operating at higher currents or in enclosed spaces.
- የኤሌክትሪክ ደህንነት; Always disconnect power before making or changing any connections. Handle with care to avoid static discharge.

Follow these steps for proper setup and wiring of the module:
- ግንኙነቶችን ማዘጋጀት; Ensure all power sources are disconnected before wiring. Use appropriate gauge wires for your current requirements.
- የግቤት ግንኙነት፡- Connect your DC input power source to the terminals labeled IN+ (አዎንታዊ) እና ውስጥ - (negative). Double-check polarity.
- የውጤት ግንኙነት፡- Connect your load or device to the terminals labeled ውጪ+ (አዎንታዊ) እና ውጪ - (negative). Double-check polarity.
- የመጀመሪያ ፍተሻ፡- 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. የአሠራር መመሪያዎች
Once wired, follow these steps to operate the buck converter:
- የግቤት ሃይል ተግብር፡ Connect your DC input power source. The red LED voltmeter display will illuminate.
- ሞኒተር ጥራዝtage: 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).
- የውጤት መጠን ያስተካክሉtage: 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 voltagሠ. ቮልትን ለመጨመር በሰዓት አቅጣጫ ያዙሩትtage, counter-clockwise to decrease. Monitor the output voltage on the LED display while adjusting.
- ውጤቱን አረጋግጥ፡ አንዴ የተፈለገውን ውፅዓት ጥራዝtage is set, you can connect your load.
ጥራዝtage display is factory calibrated and does not require additional calibration.
