Description
Product Overview
The 250W DC-DC Boost Converter Module is a high-performance step-up power supply designed for demanding applications requiring efficient voltage elevation. Engineered with Constant Voltage (CV) and Constant Current (CC) control, this module provides precise power management for battery charging, LED driving, and industrial equipment.
This non-isolated boost converter accepts a wide DC input range of 12V to 60V and delivers an adjustable output of 12V to 90V with up to 250W of power. Whether you need to boost a 12V car battery to charge a 48V LiFePO4 bank, power high-voltage LED arrays, or create a variable bench power supply, this module delivers exceptional efficiency—up to 96%—while maintaining stable operation under heavy loads .
The module features independent CV (voltage) and CC (current) adjustment via multi-turn potentiometers, making it ideal for lithium battery charging and current-sensitive applications. An integrated heatsink provides passive cooling, and the input reverse polarity protection prevents damage from accidental miswiring .
