DC-DC Boost Converter Voltage Step Up Module 400W 12A
This compact yet powerful boost converter is designed to elevate input voltages ranging from 8.5 V to 50 V up to 10 V–60 V, delivering up to 400 W of power and a maximum output current of 12 A. Housed on a 6.7 × 4.8 × 2.8 cm board with integrated screw terminals, it offers a practical and durable form factor for labs and workshops alike. Dual heat sinks efficiently manage thermal performance as current demand rises.
The module employs a non‑isolated switching design at around 150 kHz frequency, providing a clean, stable voltage output suitable for driving high-power LEDs, charging battery packs, or adapting solar panel output. Users can finely adjust voltage via a “CV‑ADJ” trimmer and set current limits using the “CC‑ADJ” potentiometer, allowing for custom constant-current or constant-voltage regimes depending on the load. A low quiescent current (~10 mA) ensures minimal energy draw when idle.
Built-in over-current protection steps in if input current surpasses 15 A, safeguarding against overloads without interrupting operation. Rated for -40 °C to +85 °C ambient with reinforced heat dissipation, this module is rugged enough for automotive, DIY, and renewable-energy setups. Whether powering laptops from 12 V batteries or regulating solar output, this 400 W boost converter offers a compact, versatile power solution optimized for hands-on power conversion tasks.
Features:
- Suitable for various electric equipment, digital products, and laptops.
- Equipped with screw terminals for easy wire connection/disconnection.
- High efficiency up to 96%, dependent on input/output voltage, current, and voltage difference.
- Enhanced heat dissipation with two built-in heat sinks.
- Versatile application as a driver for high-power LED lights or a voltage regulator for solar panels.
Output Voltage/Current Adjustment:
- Use the “CV-ADJ” potentiometer:
- Clockwise to reduce voltage.
- Counterclockwise to increase voltage.
- Adjust the “CC-ADJ” potentiometer:
- Rotate counterclockwise about 30 circles before connecting to load (clockwise to increase current, counterclockwise to reduce current).
- For battery charging, connect after the battery fully discharges to optimize charging efficiency.
