DINZHHENGYIN DC–DC Buck Converter (12V/24V to selectable fixed outputs, 1A–30A) Key benefits - Provides stable, stepped-down DC power from common 12V or 24V sources so your electronics run reliably without overvoltage stress. - Multiple fixed output options (3V, 3.3V, 3.7V, 4.2V, 6V, 7.5V, 9V) let you match the exact voltage your device requires without extra components. - Wide current availability (models from 1A up to 30A) supports small control boards to higher-current loads; a 10A Aluminum L version is available for improved thermal performance and mechanical robustness. - Compact, board-level design simplifies integration into automotive, industrial, or hobby projects where space and heat management matter. Core features - Function: Buck (step-down) DC–DC converter for efficient voltage reduction from 12V or 24V input. - Input compatibility: accepts 12V or 24V DC power sources (vehicle batteries, solar/battery systems, DC power supplies). - Fixed output voltages: 3V, 3.3V, 3.7V, 4.2V, 6V, 7.5V, 9V. Explicit support for converting 12V/24V to 3.3V for common digital electronics. - Current range: available in variants spanning 1A to 30A; the DINZHHENGYIN 10A Aluminum L version offers a durable aluminum housing for better heat dissipation. - Performance: provides a stable power supply suitable for sensitive electronics and higher-current loads. Why choose this module - Reduces design complexity by offering fixed, commonly used output voltages and a range of current capacities. - The Aluminum L version improves thermal handling and mechanical protection, increasing reliability under continuous load. - Compatible with standard 12V/24V systems used in vehicles, battery packs, and many DC power setups. Typical applications - Embedded electronics: power 3.3V microcontrollers, sensors, and communication modules from a 12V or 24V vehicle or battery supply. - Automotive and mobile power: run lighting, control modules, or accessories that require 6V–9V or low-voltage supplies from a car or RV electrical system. - Industrial and hobby projects: drive LED strips, small DC motors, or power distribution for prototyping where a stable stepped-down voltage and selectable current capacity are needed. Notes for integration - Select the model with the required output voltage and current rating (1A–30A) for your application. The 10A Aluminum L version is recommended where continuous current and heat dissipation are concerns. - Ensure correct input voltage (12V or 24V) and wiring to match the converter’s specifications.
