Custom KIT napájecí deska PLUS2 8-42V

Engineers prototyping a low-voltage system often need a reliable way to step down a wide input range to a precise output. The Custom KIT Power Supply Board Plus2 accepts 8–42V DC and delivers an adjustable output from 1.25V to 36V, making it a flexible building block for embedded projects, industrial controls, and battery-powered devices. Its compact board with screw terminals and a potentiometer allows quick integration and on-the-fly voltage adjustment.

Why choose it

This module combines a wide input range with high efficiency, reducing heat and power loss in your design. The adjustable output means one board can serve multiple voltage requirements, simplifying inventory. Screw terminals make wiring secure and tool-free, while the LED gives instant status feedback. Robust protection features safeguard both the module and your load from common faults.

Ideal use cases

• Prototyping DC-powered circuits in labs and workshops
• Powering sensors, microcontrollers, and small motors from 12V/24V batteries
• Industrial automation panels requiring a regulated low-voltage rail
• Automotive and marine electronics with fluctuating input voltages
• Educational projects and DIY electronics

Good to know

The board is designed for through-hole mounting, allowing it to be secured inside an enclosure or onto a chassis. As a non-isolated converter, it shares a common ground between input and output, which is typical for buck regulators. For best performance, ensure adequate airflow and keep input wiring short to minimize noise.
