Fonte de alimentação comutada industrial MEAN WELL HSP-300-5 300W com saída única 5V 60A com PFC ativo

Industrial and commercial systems often demand a stable, high-current 5V rail that can handle heavy loads without breaking a sweat. The MEAN WELL HSP-300-5 answers that call with a beefy 300W output and a full 60A at 5V, making it ideal for LED installations, test benches, automation controllers, and other power-hungry 5V applications.

Who is it for

This power supply is built for system integrators, machine builders, and maintenance engineers who need a reliable, compact, and efficient AC/DC converter for 5V loads. It suits indoor industrial environments where a fan-cooled unit is acceptable and where active power factor correction helps meet energy regulations.

Main features

• High power density: 300W from a compact enclosed chassis.
• Active PFC (Power Factor Correction) with PF >0.93 at 230VAC full load, reducing harmonic distortion.
• Wide input range: 180–264VAC, 47–63Hz, suitable for most mains supplies.
• Forced air cooling: requires 20CFM airflow for full 300W output.
• Comprehensive protections: short circuit, overload, over voltage, and over temperature.
• Low ripple & noise: 100mVp-p for clean 5V output.
• Safety approvals: UL60950-1 and TUV EN60950-1.

Tips

Ensure adequate airflow around the unit; without the specified 20CFM forced air, derating is necessary. For installations near sensitive electronics, consider additional filtering if the 100mVp-p ripple is too high. Always verify that the input voltage matches your mains supply (180–264VAC) before powering on.
