MEAN WELL RS-150-15 150W 15V 10A Enclosed Switching Power Supply with PFC

The RS-150-15 stands out in the 150-watt class by delivering a full 10 amps at 15 volts in a compact enclosed chassis, with a wide-range 88–264 VAC input that eliminates the need for a voltage selector switch. Unlike many competitors that derate above 40°C, this unit maintains full output up to 50°C and only derates to 60% at 70°C, making it a dependable backbone for industrial automation, LED signage, and test fixtures.

Highlights

• 150 W continuous output with 15 VDC / 10 A single rail
• Universal AC input: 88–264 VAC (47–63 Hz) or 125–370 VDC
• High efficiency up to 84% and low no-load consumption
• Built-in protections: overload, overvoltage, and short circuit
• Free air convection cooling – no fan, no noise, no maintenance
• Compact metal case with chassis-mount screw terminals

In daily use

Installation is straightforward: the RS-150-15 mounts directly to a panel or DIN rail adapter with four screws, and the clearly marked terminal block accepts ring or fork lugs. The output voltage can be trimmed from 13.5 to 18 V via the front-panel potentiometer, allowing you to compensate for cable drops or fine-tune for sensitive loads. Ripple and noise are held to 150 mVp-p, ensuring clean power for analog circuits and motor drivers. The hold-up time of 28 ms at full load (230 VAC) keeps your system alive through brief mains interruptions, while the 3 kVAC input-to-output isolation provides a solid safety barrier.
