Enclosed 3.3 V 198 W AC/DC Supply
This Mean Well RSP-320-3.3 unit delivers a fixed 3.3 V DC output rated at 60 A for 198 W total power. It suits industrial control, LED lighting, A/V equipment and RF applications that need a stable low-voltage rail in an enclosed chassis.
Verify Input Range and Mounting Space
Confirm your mains supply falls within the 100-240 V AC range before wiring the unit. Check that the enclosure dimensions fit your cabinet or rack and that the built-in fan can draw unrestricted airflow for cooling.
Thermals Noise and Protection Behaviour
The integrated fan spins during normal operation to keep internal temperatures in check, producing audible airflow noise typical of enclosed supplies. Efficiency reaches 79.5 % at full load with 1.5 % load regulation. Over-voltage, over-current, short-circuit and over-temperature protections trigger automatic recovery once the fault clears.

Questions about this item
What is included with the Mean Well RSP-320-3.3 power supply and what must be purchased separately?
The unit is an enclosed AC/DC switching power supply with built-in fan and PFC. Input and output wiring, mounting hardware and any external enclosures are not included and must be sourced separately.
Which output voltage setting should I choose for the adjustable 2.97-3.8V range on this 3.3V 60A model?
The default output is 3.3V at 60A. Adjust within the 2.97V to 3.8V range only if your load requires a different nominal voltage; ensure the connected equipment tolerates the selected setting.
What does the 198W rating mean for real-world use with 1.5% load regulation and 79.5% efficiency?
The supply delivers up to 198W continuous DC power. At full load the output voltage stays within 1.5% of the set value, and about 79.5% of input power is converted to usable DC output.
