400W 15A DC-DC Step Up Boost Converter CC CV Adjustable Power Module

Specifications

• Module Type: Non-isolated step-up module

• Input Voltage: DC 8.5V - 50V

• Input Current: 15A (Max); please enhance heat dissipation if current exceeds 8A

• Output Voltage: DC 10V - 60V (Continuously adjustable)

• Output Current: 12A (Max); related to the input and output voltage difference (higher difference = lower output current)

• Constant Current Range: 0.2A - 12A

• Output Power: = Input Voltage * 10A (e.g., 12V * 10A = 120W; 30V * 10A = 300W)

• Conversion Efficiency: Up to 96%

• Operating Frequency: 150KHz

• Operating Temperature: -40°C to +85°C

• Protection: Over-current protection (input exceeds 15A, output voltage reduces)

Key Applications & Projects

• DIY Bench Power Supply: Step up a standard 12V adapter to any voltage up to 60V for testing.

• Automotive Power Booster: Run laptops or high-power audio amplifiers in a car/truck environment.

• Solar Battery Charger: Step up solar panel voltage to charge higher voltage battery banks (e.g., 12V panel to 24V battery).

• LED Driver: Drive high-power 100W+ LED COBs with precise constant current to prevent burnout.

Project Evolution

• Past Projects (Prerequisites): If you've used basic MT3608 or XL6009 boost modules, you'll be familiar with the "step-up" concept but likely frustrated by their 2A-4A limits.

• Feature Upgrade: This board unlocks High-Current Constant Current (CC) control. This means you can limit the "push" of the electricity, making it safe to charge batteries directly or drive LEDs without external resistors.

• Effort/Requirements: Beginner-Intermediate. You just need a screwdriver and a multimeter to set your desired levels.

Virtual Technician & Wiring

⚠️ Critical Safety Note: This is a BOOST converter. The output voltage must be at least 2V higher than the input voltage for the regulation to work. Never short-circuit the output while in CC mode at high voltages.

• Input + / -: Connect your source (Battery, PSU).

• Output + / - : Connect your load (LED, Motor, Battery).

• Potentiometer 1 (CV): Adjusts Output Voltage.

• Potentiometer 2 (CC): Adjusts the Output Current limit.

Accessories

• Included: 1x 400W 15A DC-DC Boost Converter Module.

• Required Additional: Thick gauge wire (14 AWG recommended for high current), Multimeter for calibration.

Frequently Asked Questions (FAQ)

• Can this module lower the voltage? No, it is a Boost (Step-up) converter only.
• What happens if my input is 12V and I set the output to 5V? The output will be approximately 11-12V (input voltage minus diode drop); it cannot step down.
• Does it have input reverse polarity protection? No, please use a diode in series with the input if you are prone to wiring errors.
• Is the output isolated from the input? No, they share a common ground.
• How do I set the Constant Current (CC) limit? Turn the CC pot counter-clockwise (~20 turns), connect a multimeter in 10A current mode to the output, and turn clockwise until you reach the desired current.
• Can I charge a 48V battery with a 12V source? Yes, this is a perfect application for this module.
• Does it need a fan? If your output power exceeds 200W or current exceeds 8A for long periods, active cooling is highly recommended.
• What is the maximum input current? 15A.
• Can I use this to drive a 100W LED? Yes, use the CC mode to set the exact current required by the LED datasheet.
• What is the quiescent (idle) current? Approximately 15mA.
• Can I use this with a solar panel? Yes, as long as the panel's Voc does not exceed 50V.
• Are the pots multi-turn? Yes, they are high-precision 25-turn potentiometers.
• Why is my output voltage not changing? You may need to turn the pot 10-15 times counter-clockwise before you see a change if it's at the limit.
• Can I use this for an e-bike? Yes, commonly used to boost 36V batteries to 48V or 52V.
• Is it waterproof? No, it is an open-frame module.
• What is the conversion efficiency? Typically 92% to 96% depending on the voltage gap.
• Can I parallel two modules for 30A? Not recommended as the modules will not share the load equally.
• Does it have a power LED? Yes, it has an on-board indicator.
• What is the ripple voltage? Approx 50mV.
• Can I use this as a laptop car charger? Yes, it is excellent for boosting 12V to 19.5V.
