MEAN WELL RSP-75-24 76.8W 1U Low Profile Enclosed Power Supply 24V 3.2A

The MEAN WELL RSP-75-24 stands apart from typical power supplies by packing 76.8 watts into a slim 1U metal enclosure—ideal for space-constrained industrial and telecom systems. Its free-air convection cooling eliminates fan noise and maintenance, while the wide 88–264 VAC input range ensures reliable operation on unstable mains. With adjustable output voltage (21.6–26.4 V), comprehensive protections, and a >700,000-hour MTBF, this unit delivers dependable 24 VDC power for years.

Highlights

• 76.8 W output power in a 1U low-profile metal case
• 24 VDC output, adjustable from 21.6 to 26.4 V
• Universal AC input: 88–264 VAC (also accepts 124–370 VDC)
• Convection cooled—no fan, silent operation
• Protections: short circuit, overload, over voltage, over temperature
• High efficiency up to 88%
• 3 kVAC isolation, certified to UL/TUV/CE

In daily use

Install the RSP-75-24 on a chassis or DIN rail and connect your load to the screw terminals. The output voltage can be fine-tuned via the built-in potentiometer to compensate for cable drops. Its rugged metal housing withstands harsh environments, and the wide operating temperature range (-30 to +70 °C) suits outdoor cabinets or unheated equipment rooms. The power supply starts reliably even at low temperatures, making it a favorite for LED lighting, test equipment, and industrial automation.
