MEAN WELL RSP-500-24 500W 24V 20,9A gesloten voeding met actieve PFC en 1U low profile

The MEAN WELL RSP-500-24 stands apart from generic enclosed power supplies through its combination of high power density, active power factor correction, and a slim 1U profile. Built for industrial, automation, and networking environments, it delivers a regulated 24 V DC output with a rated power of 501.6 W, ensuring stable operation even under demanding loads. The built-in DC fan with speed control keeps thermal performance consistent while minimising acoustic noise at lower loads, making it suitable for both rack-mounted and standalone installations.

Highlights

• Active PFC (>0.95 at full load) reduces harmonic distortion and improves energy efficiency
• Wide input range: 85–264 V AC or 120–370 V DC, suitable for global mains and industrial DC bus applications
• Remote ON/OFF, remote sense, and DC OK signal outputs for system integration and monitoring
• Comprehensive protection: short circuit, overload, over voltage, and over temperature
• Complies with EN55022 Class B EMC and EN61000-3-2 harmonic current standards
• High MTBF of over 200,000 hours (MIL-HDBK-217F), ensuring long-term reliability

In daily use

Whether powering LED lighting arrays, motor drives, or communication equipment, the RSP-500-24 maintains a tight output regulation with a voltage adjustment range of 20–26.4 V. The remote sense function compensates for voltage drops over long cable runs, while the DC OK signal provides a real-time status indicator for control systems. The 1U height allows dense rack mounting, and the silver enclosure blends into standard equipment racks. The fan speed control reduces noise when the load is light, making it acceptable for office-adjacent installations.
