YS-U5S AC DC Switching Power Board Module with PWM Control 5V 3-150W Output

This switching power board module provides a compact and efficient solution for converting standard mains voltage to a regulated 5V DC output. Ideal for powering electronic circuits, LED lighting, or small appliances, it uses pulse width modulation (PWM) to maintain stable voltage under varying loads. The single-ended transistor connection ensures reliable switching performance. With an input range of 110 to 220V AC, it suits both domestic and international settings. The output power can be adjusted from 3 to 150W, offering flexibility for a range of applications.

Features and Construction

The module is built around a metal casing that aids heat dissipation, ensuring consistent operation even during extended use. Key electrical specifications are clearly defined for predictable performance.

PWM Control

Pulse width modulation allows precise regulation of the output voltage by rapidly switching the transistor on and off. This method reduces energy loss and improves working efficiency, which ranges from 60 to 90% depending on load and input conditions.

Electrical Specifications

The module delivers a fixed output of 5V DC with an accuracy of 3%. Output ripple noise is kept between 50 and 300mV, ensuring clean power for sensitive electronics. Voltage regulation rate is also 3%, meaning output stays within tight limits as input voltage fluctuates.

Uses and Placement

This power board is designed for integration into larger electronic assemblies, such as control panels, automation systems, or custom power supplies. Its compact size and metal enclosure allow mounting in confined spaces.

Industrial Applications

Use it to power microcontrollers, relays, sensors, or small motors that require a stable 5V supply. The wide input voltage range makes it suitable for equipment operating on different mains standards.

DIY and Repair Projects

Hobbyists and technicians can replace failed power modules in appliances or build new circuits around this board. The clearly labelled input and output terminals simplify wiring.

Benefits and Buying Value

This module offers practical advantages for anyone needing a reliable AC-to-DC conversion at low cost. Its specifications are grounded in measurable data, allowing confident integration into projects.

Efficiency and Stability

With working efficiency up to 90%, the module wastes less power as heat compared to linear regulators. The 3% output accuracy and low ripple noise help maintain consistent performance of connected devices.
