MEAN WELL RSP-1000-24 960W 1U Enclosed Switching Power Supply 24V 40A with PFC

Delivering 960 watts of continuous power from a compact 1U low-profile metal chassis, the RSP-1000-24 is engineered for demanding industrial and network applications. Active power factor correction (PFC) achieves >0.95, while high efficiency up to 90% reduces energy waste and cooling requirements. With a universal AC input range of 90–264 VAC and full protections including short circuit, overload, over voltage, and over temperature, this power supply ensures reliable operation in critical systems.

Overview

The MEAN WELL RSP-1000-24 is a 24 V DC, 40 A enclosed switching power supply designed for 1U rack-mount and industrial installations. Its built-in DC fan with speed control adjusts cooling based on load and temperature, maintaining optimal performance and extending component life. The output voltage is adjustable from 20 to 26.4 V, allowing fine-tuning for specific requirements. Remote ON/OFF, remote sense, and DC OK signal provide advanced monitoring and control capabilities for integration into complex systems.
