د خوندیتوب معلومات
Please read and understand the following safety precautions before using the module. Failure to do so may result in electric shock, fire, or damage to the module or connected devices.
- د ننوتلو حجم ډاډمن کړئtage does not exceed 38V DC.
- د ننوتلو حجمtage must always be at least 1.5V higher than the desired output voltage for proper step-down operation.
- Do not exceed the maximum output current of 5A (4.5A recommended for continuous use) or the maximum output power of 75W.
- Observe correct polarity when connecting input and output wires. Incorrect connections can damage the module.
- Avoid touching the module components while it is powered on, especially the heatsink, as they may become hot.
- Use appropriate wire gauges for connections to prevent overheating.
- This module is intended for use by individuals with sufficient knowledge of electronics.
تنظیم او پیوستون
Follow these steps to connect and prepare your DC-DC step-down module for operation.
- ایښودل (اختیاري): Use the provided pillars and screws to mount the module securely to a surface or enclosure. Ensure adequate ventilation around the module.
- د بریښنا نښلول: Connect your DC power source to the IN+ او په- د سکرو ترمینل.
- Connect the positive (+) terminal of your power source to IN+.
- Connect the negative (-) terminal of your power source to په-.
- د ننوتلو حجم ډاډمن کړئtage is within the 4.0V to 38V range.
- د محصول بار اتصال: Connect your load (the device or circuit you wish to power) to the بهر + او بهر- د سکرو ترمینل.
- Connect the positive (+) terminal of your load to بهر +.
- Connect the negative (-) terminal of your load to بهر-.
- لومړی ټوکtagد سمون Before connecting a sensitive load, it is recommended to adjust the output voltage.
- Power on the module. The LED voltmeter will display the voltage.
- Use a small screwdriver to turn the multi-turn potentiometer (usually a blue square component with a metal screw) to adjust the output voltage. Turn clockwise to increase voltage, counter-clockwise to decrease.
- مهمه یادونه: که د تولید حجمtage does not change initially, or if it always equals the input voltage, turn the potentiometer counter-clockwise for at least 10-15 full turns. This is because the potentiometer may be set to its maximum resistance from the factory, preventing immediate voltage کمول.
- د محصول حجم تایید کړئtage with an external multimeter for precise adjustment, especially for critical applications.
عملیات
Once connected and adjusted, the module is ready for operation.
Voltmeter Functions
- The integrated LED voltmeter displays the voltage.
- د لیبل شوي تڼۍ فشار ورکړئ S1 (or similar, typically near the display) to switch between displaying the input voltage او د محصول حجمtage. An indicator LED (e.g., "IN" or "OUT") will illuminate to show which voltage is currently being displayed.
- To turn off the voltmeter display, press and hold the S1 button for approximately 1-2 seconds. Press it again briefly to turn the display back on.
- The module remembers the last display setting (input/output/off) even after power cycling.
د محصول Voltage سمون
د محصول حجمtage is adjusted using the multi-turn potentiometer.
- Turn the potentiometer clockwise to increase the output voltage.
- Turn the potentiometer counter-clockwise to decrease the output voltage.
- Make small adjustments and observe the voltmeter or an external multimeter to reach the desired voltage.
ساتنه
The HiLetgo DC-DC Step Down Power Module is designed for reliable operation with minimal maintenance.
- Keep the module clean and free from dust and debris.
- Ensure proper ventilation to prevent overheating, especially when operating at higher currents.
- Periodically check wire connections for tightness and corrosion.
- Avoid exposing the module to moisture or extreme temperatures.
د ستونزو حل کول
- ستونزه: د تولید حجمtage does not change or is equal to input voltage.
- حل لاره: The potentiometer may be at its maximum setting from the factory. Turn the adjustment potentiometer counter-clockwise for at least 10-15 full turns. You should then observe the voltage starting to decrease and become adjustable.
- Problem: No display on the voltmeter.
- حل لاره: د ننوتلو حجم ډاډمن کړئtage is at least 4.5V for the voltmeter to function accurately. Check if the voltmeter display was intentionally turned off (press the S1 button briefly to toggle it on). Verify input power connections.
- ستونزه: د تولید حجمtage is unstable or fluctuates.
- حل لاره: Check input power source stability. Ensure connections are secure. Verify that the load current does not exceed the module's maximum rating (5A, 4.5A recommended).
- Problem: Module becomes excessively hot.
- حل لاره: Reduce the load current or ensure adequate ventilation. Consider adding a larger heatsink if operating at higher currents for extended periods.
