MEAN WELL RSP-150-24 150W 24V 6.25A Enclosed Power Supply with Active PFC and 1U Low Profile

The MEAN WELL RSP-150-24 stands out as a remarkably slim 1U-height enclosed power supply that delivers a full 150 watts from a 24V rail, making it an excellent choice for space-constrained industrial and automation systems where conventional bricks simply won’t fit. Unlike many compact units that sacrifice efficiency or protection, this model combines active power factor correction, a wide 85–264V AC input, and a robust set of safety features in a passively cooled chassis that runs silently and reliably.

Highlights

• 150W output power with 24V DC at 6.25A for demanding loads
• Active PFC (>0.95 at 230VAC) reduces harmonic distortion and improves energy efficiency
• Ultra-low profile 1U form factor (30mm height) fits into shallow racks and tight enclosures
• Wide input range: 85–264V AC or 120–370V DC, with 47–63Hz frequency support
• Comprehensive protections: short circuit, overload, over voltage, and over temperature
• Free air convection cooling – no fan, no noise, no moving parts to wear out
• High efficiency up to 89% and low ripple & noise (150mVp-p)
• Meets UL60950-1, TUV EN60950-1, CB, and CE safety standards; EMC compliant with EN55022 Class B

In daily use

In a typical control cabinet or LED signage installation, the RSP-150-24 provides clean, stable power without the acoustic footprint of fan-cooled supplies. Its active PFC ensures compliance with modern power quality regulations, while the wide operating temperature range from -30°C to +70°C allows deployment in harsh environments. The 3KVAC input-to-output isolation adds an extra layer of safety for sensitive downstream electronics, and the >300,000 hour MTBF means you can install it and forget it. Setup time is a quick 500ms at full load, and the 16ms hold-up time keeps outputs stable during brief mains interruptions.
