MEAN WELL RSP-75-15 75W 15V 5A 1U Enclosed Power Supply with Active PFC

Industrial and commercial systems often struggle to find a power supply that delivers stable 15V DC output within tight space constraints. The MEAN WELL RSP-75-15 solves this by packing 75W of reliable power into a slim 1U low-profile metal enclosure, making it ideal for rack-mounted equipment, automation controllers, and LED lighting arrays where every millimetre counts.

Who is it for

System integrators, panel builders, and maintenance engineers who need a dependable 15V DC source for industrial electronics, test fixtures, or communication devices. Its wide input range and active PFC make it suitable for both 115V and 230V mains environments, including generator or unstable grid conditions.

Tips

When mounting multiple RSP-75-15 units side by side, leave at least 15mm clearance on all sides for proper convection airflow. For applications with high inrush current at startup, consider using an external soft-start circuit or ensure the upstream breaker is rated accordingly. The output voltage can be fine-tuned via the front-panel potentiometer to compensate for voltage drops in long cable runs.
