HW-788 DC 6-100V to 5V 2A Step-Down Voltage Module

HW-788 DC 6-100V to 5V 2A Step-Down Voltage Module

The HW-788 DC 6-100V to 5V 2A Step-Down Voltage Module is a high-voltage buck power module designed to convert a wide DC input range into a stable 5V output. Supporting an output current of up to 2A, it is ideal for directly powering microcontrollers, sensors, communication modules, and other 5V electronic components from high-voltage sources.

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

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

Specifications

• Input Voltage: 6-100V DC
• Output Voltage: 5V DC
• Current: Maximum 2A

Output Voltage Adjustment

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