MEAN WELL RS-150-48 Enclosed Switching Power Supply 158.4W 48V 3.3A 88-264VAC

The MEAN WELL RS-150-48 stands out in the RS series with its high efficiency and robust enclosed design, delivering reliable 48V DC output for industrial and commercial applications. Unlike open-frame units, its fully enclosed metal case provides superior protection against dust and accidental contact, making it suitable for integration into machinery, automation systems, and LED lighting installations where safety and longevity are paramount.

Highlights

• 158.4W total power with 48V DC output and 3.3A current
• Wide input range: 88-264VAC (47-63Hz) or 125-370VDC
• High efficiency up to 87% reduces energy waste and heat
• Comprehensive protections: overload, overvoltage, short circuit
• Free air convection cooling – no fan, silent operation
• Compact enclosed form factor for easy integration

In daily use

This power supply operates reliably across a wide temperature range from -25°C to +70°C, with full power available up to 50°C and derating above. Its hold-up time of 28ms at full load ensures stable output during brief input interruptions. The unit meets UL60950-1 and TUV EN60950-1 safety standards, and EN55022 Class B EMC compliance minimizes electromagnetic interference. With no fan, it requires no maintenance and is ideal for noise-sensitive environments.
