Description
Product Overview
The 400W 15A High-Power DC-DC Boost Converter is a professional-grade step-up voltage regulator designed for demanding applications requiring efficient voltage elevation. This non-isolated boost module can increase a lower DC input voltage (8.5V-50V) to a higher, user-adjustable output voltage (10V-60V), delivering up to 400W of power and 15A of peak current .
This module stands out with its dual-mode constant voltage (CV) and constant current (CC) control, which is essential for applications like high-power LED driving and battery charging. The onboard multi-turn potentiometers allow independent adjustment of both output voltage and current limit, while the dual heatsinks ensure effective thermal management during high-power operation .
Whether you need to power a 36V LED array from a 12V battery, charge a 24V lithium battery pack, or create a variable bench power supply, this 400W boost converter provides the power, flexibility, and reliability required for professional and DIY projects .
