DINZHHENGYIN DCDC Step-Down Module — Reliable voltage conversion for home and mobile systems Why you need it - Safely power 12V or 5V devices from higher-voltage sources. This module prevents overvoltage damage when you need to run 12V appliances or 5V electronics from 24V systems. - Versatile compatibility with a wide range of power sources — batteries, alternators, solar charge controllers, and other DC supplies — thanks to a broad input range. - Rugged, waterproof, and shockproof design lets you use it in demanding environments where moisture or vibration are a concern. Key benefits - Multiple output options: choose the appropriate current rating (1A, 2A, or 3A) for 24V-to-12V conversion to match the load and improve reliability. - High-current 5V output: built-in buck converter converts 24V to 5V with a 5A output for USB hubs, controllers, or other 5V peripherals. - Wide input voltage range: accepts 8–35V input, making it compatible with 12V and 24V systems and tolerant of voltage variation. - Rugged construction: waterproof and shockproof module housing increases durability in outdoor, automotive, or industrial installations. - Brand assurance: product from DINZHHENGYIN, maintaining the specified functions and options. Specifications (models and functions) - Input voltage: 8–35V DC - 24V → 12V output options: 1A, 2A, or 3A (selectable model) - 24V → 5V output: 5A (buck converter) - Specific model example: 24V → 12V at 3A - Alternate version available: converts 12V/24V → 12V at 3A - Environmental protection: waterproof and shockproof module Typical applications - Home appliances and electronics: run 12V lamps, fans, or control modules from a 24V supply without risk of overvoltage. - Mobile and automotive use: power 5V devices (up to 5A) or 12V accessories in trucks, RVs, or boats where the vehicle electrical system is 24V. - Renewable energy and backup systems: step down variable battery or solar outputs (8–35V range) to stable 12V or 5V supplies for controllers, sensors, and small loads. Selection tips - Choose the 24V→12V 1A/2A/3A model based on the continuous current your 12V device requires; the 3A variants are available for heavier loads. - If you need to power high-current 5V devices, choose the 24V→5V 5A buck converter model. - For installations where the supply may be either 12V or 24V, consider the 12V/24V→12V 3A version to simplify wiring and inventory. DINZHHENGYIN DCDC modules provide straightforward, durable voltage conversion for systems that require reliable 12V or 5V power from higher-voltage sources.
