Power supply unit Synergy21 MEAN WELL RS-150 130 W, AC 115–230 V, metallic casing

Synergy21 MEAN WELL RS-150 is an AC-to-DC power supply unit delivering up to 130 W in a compact metallic housing (98 × 199 × 38 mm). It accepts a wide AC input range of 115–230 V at 47–63 Hz and provides stable, low-noise DC power for industrial and embedded applications. The unit is designed for continuous operation with a fast 20 ms rise time, 2% voltage tolerance and an MTBF of approximately 244000 hours, making it suitable where reliable long-term performance is required.

Advantages

The metallic casing supports efficient heat dissipation and mechanical robustness while cooling is achieved by free air convection, eliminating moving parts. Built-in protections include short-circuit, overload and over-voltage safeguards. The supply uses long-life electrolytic capacitors rated for 105 °C and passes a 100% full-load burn-in test to ensure consistent performance. Additional design features include the ability to withstand a 300 VAC surge for 5 seconds, operation at ambient temperatures up to 70 °C, and resistance to 5 g vibration. An LED power indicator provides immediate visual status.

How to use

Install the power supply in a dry, well-ventilated location with sufficient clearance for convection cooling and secure it using the provided mounting points. Connect the AC input within the specified 115–230 V range and attach the DC output to the load ensuring correct polarity. Verify connections before powering on and observe the LED indicator for power status. Avoid covering ventilation openings and maintain ambient temperature below the maximum rated value for continuous operation.

Recommendations

For reliable long-term operation, perform initial commissioning under full-load conditions to confirm stable output, and allow periodic visual inspections for secure connections and adequate ventilation. If the application experiences frequent transients, consider additional upstream surge protection despite the unit's 300 VAC surge tolerance. Follow applicable safety and grounding practices when installing in industrial environments.
