ATTE ASDC-30-AD0-OF Adjustable Step-Down Voltage Converter 3-12V 3A

The ATTE ASDC-30-AD0-OF is a high-efficiency DC/DC step-down (buck) converter designed to reduce input voltages from 12-30V DC to a continuously adjustable output of 3-12V DC. With a continuous output current of 3A (peak 4A) and maximum output power of 36W, this converter is ideal for powering a wide range of electronic devices and projects. Its compact, surface-mount design with screw terminals ensures easy integration into various applications.

Advantages

This converter offers exceptional flexibility with its adjustable output voltage, allowing you to precisely set the voltage to match your device requirements. The high conversion efficiency (>90%) minimizes power loss and heat generation, while the passive cooling design ensures silent operation. Built-in protection features (overload, short circuit, overvoltage, overheating) safeguard both the converter and connected equipment.

Suitable for

• Powering LED strips, motors, and other DC devices requiring a stable voltage lower than the input
• DIY electronics projects, robotics, and embedded systems
• Automotive and marine applications where input voltage varies (e.g., 12V or 24V systems)
• Industrial control systems and automation equipment
