2. Sikkerhedsoplysninger
Please read and understand all safety warnings and instructions before operating this device. Failure to do so may result in electric shock, fire, or serious injury.
- Do not exceed maximum or minimum input/output voltage og nuværende grænser. Operating outside specified parameters can damage the module and connected devices.
- Avoid short-circuiting the output. Adjusting output current by short-circuiting is strictly prohibited.
- Do not charge supercapacitors directly with this module.
- Ensure the input power supply capacity is at least 1.5 times the load power to prevent instability or damage.
- This module generates heat during operation. Ensure adequate ventilation and do not obstruct the cooling fan.
- Handle with care. This is an exposed circuit board and requires caution to prevent accidental contact with live components.
- Afbryd altid strømmen, før du foretager tilslutninger eller justeringer.
- Use appropriate wire gauges for input and output connections to handle the expected current.

5. Opsætning og forbindelser
Before connecting the module, ensure all power sources are disconnected.
- Identificer terminaler: Locate the input (VIN+, VIN-) and output (OUT+, OUT-) terminals on the module.
- Indgangsforbindelse: Connect your DC input power source to the VIN+ (positive) and VIN- (negative) terminals. Ensure correct polarity. The module has reverse polarity protection, but incorrect connection should still be avoided.
- Udgangsforbindelse: Connect your load to the OUT+ (positive) and OUT- (negative) terminals.
- Montering: Use the provided standoffs and nuts to securely mount the module in a well-ventilated area, ensuring the cooling fan has unobstructed airflow.
Figure 5.1: This diagram illustrates the input (VIN+, VIN-) and output (OUT+, OUT-) terminals, along with the adjustment potentiometers for output voltage (CV), output current (CC), and input undervoltage protection (UVP). Indicators for output voltage and overcurrent are also shown.
6. Betjeningsvejledning
The module features three adjustable potentiometers:
- CV (Constant Voltage) Potentiometer: Justerer udgangsvolumentage. Turn clockwise to increase, counter-clockwise to decrease.
- CC (Constant Current) Potentiometer: Adjusts the output current limit. Turn clockwise to increase, counter-clockwise to decrease.
- UVP (Undervoltage Protection) Potentiometer: Adjusts the input undervoltage protection threshold. Turn clockwise to increase the protection voltage, counter-clockwise to decrease.
6.1. Udgang Voltage Adjustment (CV)
- Connect the input power supply.
- Connect a voltmeter to the output terminals.
- Adjust the CV potentiometer until the desired output voltage er nået.
- Note: When setting the output voltage to 120V, the input voltage must be 20V or higher.
6.2. Output Current Adjustment (CC)
- First, set the output voltage (CV) to the desired level.
- Connect an ammeter in series with the output load, or use a suitable electronic load.
- Adjust the CC potentiometer until the desired output current limit is reached.
- Vigtig: Do not adjust the output current by short-circuiting the output terminals. This can damage the module.
6.3. Input Undervoltage Protection Adjustment (UVP)
- Connect the input power supply.
- Adjust the UVP potentiometer to set the desired minimum input voltage. Hvis input voltage drops below this threshold, the module will stop outputting power to protect the input source (e.g., battery).
- The UVP indicator LED will illuminate when undervoltage-beskyttelsen er aktiv.
Calculation for Operating Current: Output Power / Input Voltage * 1.06 (1.06 accounts for power loss). Ensure the calculated operating current does not exceed the maximum input current of your power source.
7. Vedligeholdelse
Regular maintenance helps ensure the longevity and optimal performance of your boost converter module.
- Rensning: Periodically clean the module, especially the heat sink and fan, to remove dust and debris. Use compressed air or a soft brush. Ensure power is disconnected before cleaning.
- Ventilatorbetjening: The cooling fan is temperature-controlled and will only activate when the heat sink temperature reaches approximately 40°C. This reduces noise and extends fan life. Ensure the fan is spinning freely when active.
- Udskiftning af sikring: The module is equipped with replaceable fuses. If a fuse blows, disconnect power, identify the faulty fuse, and replace it with a fuse of the same rating. Spare fuses are included.
- Forbindelser: Periodically check all input and output connections to ensure they are secure and free from corrosion.
