MEAN WELL LRS-50-15 50W 15V Enclosed Power Supply

Automation engineers and system integrators often need a reliable, compact power source for industrial control panels, LED lighting arrays, or test benches. The MEAN WELL LRS-50-15 delivers a stable 15 V DC output in a slim metal enclosure, making it a practical choice for space-constrained installations that still demand dependable performance.

Key specifications

• Output: 15 V DC, 3.4 A, 51 W maximum
• Wide input range: 85–264 V AC or 120–370 V DC
• High efficiency up to 85% and low no-load consumption below 0.5 W
• Built-in protections: short circuit, overload, over voltage
• Free air convection cooling – no fan required, silent operation
• Operating temperature: -30 °C to +70 °C
• Safety approvals: UL60950-1, TUV EN60950-1, CB, CE
• EMC compliance: EN55032 Class B, harmonic current EN61000-3-2 Class A
• Isolation: 3 kV AC input to output
• Compact metal case with chassis mount screw terminals

Why choose it

This power supply balances cost and capability. Its wide input voltage range handles unstable mains or DC bus systems, while the metal housing provides durability in industrial environments. The adjustable output (13.5–18 V) lets you fine-tune for voltage drop over long cable runs. With no fan, it runs silently and reduces maintenance concerns.

Ideal use cases

• Industrial automation and control systems
• LED lighting and signage
• Test and measurement equipment
• Telecommunication devices
• General electronic projects requiring a reliable 15 V rail
