Shipping
We are an online wholesale platform and shipping costs are charged separately for greater benefit to you.
Air freight costs are based on the weight of the product (including packaging bags and cushioning materials). For products under 2kg, freight is calculated in 50g increments. For products between 2kg and 4kg, freight is calculated in 100g increments. For products over 4kg, freight is calculated in 1kg increments.
If your order exceeds 4kg or the shipping cost exceeds $70, we recommend contacting our customer service for an accurate shipping quote. You will need to provide your zip code address when you contact us.
Air freight options include DHL, UPS, FedEx, and Yun Express, with a delivery time of 7-12 days.
When the weight of the express delivery exceeds 12kg or air shipping cost exceeds US$100 or sea shipping cost exceeds US$50, you can choose B2B shipping:
Air freight(10-14 days)
Yun quik boat sea freight (15-20 days)
Quik boat sea freight(20-25 days).

Processing starts after your payment confirmed. Normally, it needs 2-5 days. The processing time depends on the quantity of items.
Connect to a power supply (3-40V), adjust the blue potentiometer knob (generally clockwise for increased voltage, counter-clockwise for decreased voltage), and use a multimeter to monitor the output voltage until the required voltage is reached.
Wiring Methods:
1. Soldering: Directly solder the power cord to the input (output) port.
2. Soldering Pins: Insert leads into pins or use the module on a perforated board; alternatively, add pins and solder directly onto the PCB.
Application Examples:
1. Car Power Supply: Simply connect the module's input to the car's cigarette lighter socket, adjust the potentiometer, and the output voltage can be adjusted arbitrarily from 1.25-30V, powering many devices such as mobile phones, MP3 players, MP4 players, and PSPs. It's very simple and convenient.
2. Powering Electronic Devices: When a device requires 3-35V power and you don't have a corresponding power supply, this module can easily adjust the voltage to the required level, solving the problem.
3. System Operating Voltage Testing: During project work, this module can be used to debug various voltage testing system operating voltage ranges, making it very easy and convenient.
X7R high-Q, high-frequency bypass capacitors are added to both the input and output terminals, ensuring superior electromagnetic compatibility!
Input voltage range: DC 3.2V to 46V. Recommended for use within 40V! (The input voltage must be at least 1.5V higher than the output voltage. Boosting is not supported.)
Output voltage range: DC 1.25V to 35V. Continuously adjustable voltage, high efficiency (maximum 92%), maximum output current 3A.
Measured load regulation is less than 1% with a 12V input and a 5V output current of 1A.
Note: This is a step-down module; the input voltage must be higher than the output voltage.
Outputs below 2A can operate without a heatsink for extended periods. For output currents greater than 2.5A (or output power greater than 10W), a heatsink is required for prolonged operation.
Input voltage: 3.2V~46V (recommended for use within 40V)
Output voltage: 1.25V~35V
Output current: 3A (maximum)
Conversion efficiency: 92% (maximum)
Output ripple: <30mV
