1500W DC-DC Step Up Boost Converter Module

High-Power DC-DC Boost Converter for Demanding Projects

This 1500W DC-DC step up boost converter is designed for applications that require higher output voltage from a lower DC input source. It is well suited for powering high-power LEDs, motors, battery systems, solar setups, and other electronics projects where adjustable voltage and current control are important.

Powerful Design with Heavy-Duty Components

The module uses double sendust magnetic cores wound with thick 1.2 mm copper wire for improved efficiency and current handling. High-current, low-resistance MOSFETs allow the converter to handle large input and output power levels, making it suitable for demanding loads that require stable performance.

Adjustable Voltage and Constant Current Control

Both output voltage and output current are adjustable using onboard potentiometers. This allows the module to be used for general power conversion as well as constant current applications such as battery charging or LED driving. Voltage adjustment is smooth, though changes may respond slowly due to large output capacitance.

Built-In Protection for Safer Operation

This boost converter includes multiple protection features to help prevent damage during use. Reverse input protection helps guard against accidental wiring mistakes. Adjustable low input voltage protection helps protect batteries from over-discharge. Over-current and short-circuit protection are also included for added safety during operation.

Active Cooling and Thermal Management

A thickened heatsink combined with an intelligent temperature-controlled cooling fan helps dissipate heat effectively during high-power operation. Additional airflow or external cooling is recommended when operating at higher currents for extended periods.

Basic Adjustment and Usage Notes

Voltage is adjusted using the V-ADJ potentiometer with no load connected. Output current should be set to minimum before connecting a load, then adjusted upward as needed. For battery charging applications, connect the battery after it is fully discharged to allow proper current regulation.

Important Usage Notes

• Do not reverse or short the output wiring
• For inductive loads, higher input voltage and reduced output power are recommended
• When using batteries, solar panels, or generators, add your own low voltage protection carefully to avoid damage
