Power supply unit MEAN WELL RSP-200-48 201.6 W 48 V 1U metallic, 88–264 V AC input

MEAN WELL RSP-200-48 is a compact industrial power supply that delivers 48 V DC at a total output power of 201.6 W in a 1U low-profile metallic enclosure. Designed for use where a reliable, efficient 48 V source is required, this unit accepts a wide AC input range of 88–264 V at 47–63 Hz and incorporates active PFC to maintain a power factor greater than 0.95. The product’s dimensions (115 × 215 × 30 mm) and metallic construction make it suitable for rack-mounted systems, embedded equipment and other industrial installations that require a robust, space-saving power solution.

Advantages

The RSP-200-48 offers high conversion efficiency of up to 90%, reducing heat generation and improving overall system energy use. Built-in active PFC and universal AC input ensure stable operation across a wide mains voltage range and improve compatibility with different power environments. Its 1U low-profile metallic case provides mechanical strength and effective electromagnetic shielding, and the optional conformal coating increases resilience in harsher environments. An LED status indicator simplifies basic operational checks.

How to use

Install the RSP-200-48 into a compatible 1U mounting space or secure it within the equipment chassis following the manufacturer’s mechanical guidelines. Connect the AC supply within the specified 88–264 V range and verify correct grounding to maintain safety and reduce interference. Connect the 48 V DC output to the load using appropriately sized wiring and secure terminal connections to handle the rated current. Allow adequate ventilation around the unit and avoid obstructing airflow through the housing.

Usage recommendations

Operate the supply within rated ambient temperature limits, ensure proper chassis grounding, and follow local wiring codes. For deployments in dusty, humid, or corrosive environments, consider the optional conformal coating. Periodically inspect connections and ventilation paths; when integrating into racks, provide clearance for airflow and heat dissipation to maintain efficiency and longevity.
