- Dimensions (without shell): 120 × 96 × 28 mm
- Condition: Brand New
- High-Concern Chemicals: None
Why Choose This Buck Module?
- ✅ Wide input range – Compatible with a broad array of DC power sources from 25V to 90V
- ✅ Broad adjustable output – Dial in precisely the voltage your project demands (2.5V–50V)
- ✅ High peak current – Handles the surge demands of power tools without flinching
- ✅ Robust, enclosed design – Shell provides physical protection for the circuitry
- ✅ Compact & mountable – Fits neatly into custom enclosures or workshop setups
Important Notes
- This module is a step-down (buck) converter only — the output voltage must always be lower than the input voltage; it cannot boost voltage.
- This module does not have a constant-current function and is not suitable for direct battery charging applications.
- If the module temperature exceeds 75°C during prolonged use, ensure adequate ventilation and additional heat dissipation (e.g., a heatsink fan).
- Measurements are taken manually; slight dimensional tolerances may apply — actual product dimensions prevail.
Made in Mainland China.

Frequently Asked Questions
Q: What is the maximum output power of this DC-DC buck converter module?
A: This step-down converter module delivers a maximum output power of 1000W, with a continuous output current of 35A and a peak current of 50A, making it well-suited for high-demand applications like power tools and custom power supplies.
Q: Can I use this buck module to charge batteries?
A: No. This module does not feature a constant-current (CC) function and is therefore not suitable for directly charging batteries or other devices that require constant-current output. It is designed purely as a voltage regulator for powering loads.
Q: What input voltage range does this step-down converter accept?
A: The module accepts an input voltage range of DC 25V to 90V. The output can be adjusted between DC 2.5V and 50V, provided the output voltage is always set lower than the input voltage (step-down only).
Q: What should I do if the module gets too hot during extended use?
A: If the module's temperature exceeds 75°C during prolonged operation, you should improve airflow and heat dissipation — for example, by adding a heatsink, fan, or placing the module in a better-ventilated enclosure. This helps maintain stable performance and prolongs the module's service life.
