Factory Customization

This 400W switching power supply features an all-in-one design with built-in AC power inlet, on/off switch, and DC output terminals, making it plug-and-play for quick setup.

With 100% true full power output, it avoids the power inflation common in cheap power supplies. We recommend reserving 20% power margin for industrial loads to handle startup surge, voltage fluctuations and long-term aging.

Built-in cooling fan ensures efficient heat dissipation, supporting 24-hour continuous full-load operation. Multiple safety protections include overvoltage, overcurrent, short circuit and overheat protection.

The compact metal case with ventilation holes ensures good heat dissipation and long lifespan. It is widely used in applications requiring stable DC power with easy connection.

Use Cases：

• Desktop 3D printers and CNC equipment power supply
• Industrial automation equipment, PLC and control systems
• DIY projects, electronic testing and laboratory power supply
• LED lighting, signboards and display screens
