HW-788 DC 10-100V to 9V 2A Step-Down Voltage Module

HW-788 DC 10-100V to 9V 2A Step-Down Voltage Module

The HW-788 DC 10-100V to 9V 2A Step-Down Voltage Module is a compact, high-efficiency step-down voltage regulator designed to provide reliable power conversion. By delivering a stable 9V output from a wide input range of 10V to 100V, it offers an ideal solution for automotive, e-bike, and industrial electronics applications. Featuring built-in over-current and over-temperature protection, low-ripple output, and natural heat dissipation, this module ensures safe and stable operation in space-constrained systems.

Its wide input range makes it suitable for automotive systems, industrial equipment, battery-powered systems, and solar energy applications. Its compact and efficient design delivers stable performance with reliable voltage regulation, making it an excellent choice for both hobbyist (DIY) and professional projects.

NOTE: Since this is a step-down (buck) converter, the output voltage must always be lower than the input voltage.

Specifications

• Input Voltage: 10-100V DC

Output Voltage Adjustment

The module provides the output voltage corresponding to the pad where the resistor is placed (as indicated in the image). This allows for selectable outputs of 5V, 9V, 12V, or 24V. Since this is a step-down converter, the output voltage must always be lower than the input voltage.
