4. Gwybodaeth Diogelwch
- Mewnbwn Voltage Terfyn: Do not exceed 30V DC input. Exceeding this limit can damage the module.
- Buck Module Operation: Sicrhau bod y mewnbwn cyftage 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.
- Gwasgariad gwres: While the metal case acts as a heat sink, ensure adequate ventilation, especially when operating at higher currents or in enclosed spaces.
- Diogelwch Trydanol: Always disconnect power before making or changing any connections. Handle with care to avoid static discharge.

6. Gosod a Gwifro
Follow these steps for proper setup and wiring of the module:
- Paratoi Cysylltiadau: Ensure all power sources are disconnected before wiring. Use appropriate gauge wires for your current requirements.
- Cysylltiad Mewnbwn: Connect your DC input power source to the terminals labeled YN+ (cadarnhaol) a YN- (negative). Double-check polarity.
- Cysylltiad Allbwn: Connect your load or device to the terminals labeled ALLAN+ (cadarnhaol) a ALLAN- (negative). Double-check polarity.
- Gwiriad Cychwynnol: 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. Cyfarwyddiadau Gweithredu
Once wired, follow these steps to operate the buck converter:
- Cymhwyso Pŵer Mewnbwn: Connect your DC input power source. The red LED voltmeter display will illuminate.
- Monitor Cyftage: 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).
- Addasu Allbwn Voltage: 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 voltage. Turn clockwise to increase voltage, counter-clockwise to decrease. Monitor the output voltage on the LED display while adjusting.
- Gwirio Allbwn: Unwaith y bydd yr allbwn a ddymunir cyftage is set, you can connect your load.
Mae'r cyftage display is factory calibrated and does not require additional calibration.
