China 24V 350W SMPS Switching Power Supply Suppliers, Manufacturers - Factory Direct Price

Product Details

Buy quality 24V 350W SMPS Switching Power Supply from STARWELL, a professional manufacturer in China. Designed for efficiency, this switching power supply operates with a typical efficiency of over 80%, minimizing energy loss and heat generation. Its compact, fully enclosed metal case provides durability, effective shielding, and easy mounting. A built-in cooling fan automatically manages internal temperatures, ensuring stable output even during prolonged high-load operation.

Power Your Projects with Industrial Reliability

The S-350 Series Aluminum Switching Power Supply delivers uncompromising 350W of clean, stable DC power. Available in 12V (29A) and 24V (14.6A) outputs, this unit is the ideal solution for LED displays, CCTV systems, CNC routers, 3D printers, audio amplifiers, and industrial automation.

Genuine Industrial-Grade Components

Unlike inferior "copper-clad aluminum" counterfeits on the market, our S-350 power supply is built for longevity. It features a pure copper transformer (never short on weight) and high-quality brand capacitors—not reconditioned or secondary processed parts. An integrated EMI filter ensures cleaner output with reduced electrical noise, providing better stability for sensitive equipment.

Comprehensive Protection Suite

Your devices are fully guarded. The S-350 includes Overvoltage Protection (OVP) , Overload Protection (OLP) , Over-Temperature Protection (OTP) , and Short-Circuit Protection (SCP). These safety features automatically shut down the unit under fault conditions, preventing damage to both the power supply and your connected load.

User-Friendly & Adjustable

The enclosed aluminum housing measures 215mm × 115mm × 50mm, offering efficient passive cooling and durable shielding. An onboard potentiometer allows output voltage adjustment of ±10% , giving you fine-tuning flexibility. Clearly labeled terminals (AC input L/N/Ground, DC output +/-V) simplify wiring.

Fast Delivery & Warranty

We ship via FedEx or UPS, with the fastest delivery available in 24 hours. Official invoices are provided, and every unit is backed by a long warranty.
