MEAN WELL RSP-500-48 504W 48V 10.5A Enclosed Switching Power Supply with PFC

Industrial-grade enclosed AC/DC power supply delivering a regulated 48V DC output at up to 10.5A, with a total rated power of 504W. The RSP-500-48 combines active power factor correction, a wide input voltage range, and comprehensive protection features to ensure reliable operation in demanding automation, control, and communication systems.

Advantages

The RSP-500-48 achieves up to 90% efficiency, reducing energy waste and heat generation. Active PFC (typically 0.95) minimizes harmonic distortion and improves power utilization. A built-in DC fan with speed control automatically adjusts cooling based on load and temperature, extending component life. Remote ON/OFF, remote sense, and DC OK signal outputs simplify system integration and monitoring.
