DINZHHENGYIN DC–DC Buck Converter — reliable step-down power for electronics and vehicles Key benefits - Converts common vehicle and battery voltages (12V or 24V) down to precise working voltages, preventing over-voltage damage to sensitive electronics. - Wide current range (1A to 30A) covers small control boards up to higher-current loads, letting you choose the right model for your power needs. - Multiple fixed output options (3V, 3.3V, 3.7V, 4.2V, 6V, 7.5V, 9V) for direct compatibility with standard logic levels, battery targets, and peripheral devices. - The 4A Aluminum S model provides a dedicated 3.3V output from 12V or 24V input and is built in an aluminum enclosure for improved thermal handling and durability. - Stable voltage reduction provides consistent power delivery to prevent resets, noise, or component stress in sensitive systems. Features and specifications - Function: DC to DC buck (step-down) converter for converting higher DC input voltages to lower DC outputs. - Input compatibility: 12V or 24V DC. - Available output voltages: 3V, 3.3V, 3.7V, 4.2V, 6V, 7.5V, 9V. - Output current range across models: 1A to 30A to match different load requirements. - Model highlight: 4A Aluminum S — 3.3V output from 12V/24V input, aluminum housing for heat dissipation and mechanical protection. - Intended use: provides a stable, regulated supply for electronic devices and subsystems. Practical applications - Embedded systems and sensors: power 3.3V microcontrollers, sensors, and communication modules directly from vehicle or battery sources without separate regulators. - Vehicle and industrial electronics: step down 12V or 24V automotive or industrial power rails to 6V, 7.5V or 9V for lighting, control modules, or actuators. - Battery-powered systems and testing: provide 3.7V or 4.2V outputs for development, bench testing, or powering circuits that match lithium cell voltages. Why choose this converter - Flexible selection of output voltages and currents lets you match the converter to the device requirements without extra wiring or adapters. - DINZHHENGYIN brand models are designed to integrate with common 12V/24V systems and to deliver steady output under varying loads. - The Aluminum S variant combines a specified 4A output with a protective aluminum enclosure for reliable thermal performance in continuous operation. Compatibility and installation notes - Designed to accept 12V or 24V DC inputs; select the model that matches your required output voltage and current capacity. - Choose a model within the 1A–30A range to ensure safe, reliable operation for your load. - Use appropriate wiring, fusing, and mounting practices consistent with the chosen current rating and installation environment.
