MEAN WELL SP-320-3.3 Switching Power Supply (Output 3.3Volts, 55Amps)

The MEAN WELL SP-320-3.3 is an impressive, enclosed power supply offering rated 181.5W output power with 74% efficiency for optimal performance. It takes full-range 100-240 VAC inputs and offers 3.3V producing 55A with an adjustable range of 3.14-3.63V in three consistent output channels.

The SP-320-3.3 maintains a constant duty cycle to regulate the output voltage and reduces load regulation error to an outstanding ±0.5% level due to its high switching frequency (100KHz). It is ideal for LED and A/V equipment, and industrial applications requiring consistent and reliable performance.

In addition to the excellent protections such as overload, over temperature protections (with automatic recovery), and over-voltage, short circuit protections, it is certified by UL60950-1, EN55032, EN61000-3-2, EN61000-4-2, EN55024 which allow it to meet the worldwide energy requirement.

This AC/DC, standard-sized SP-320 series ensures long-term operation in demanding environments through its built-in DC fan, which performs without faults in various temperatures ranging from -20°C to +60°C.

Meanwell's AC/DC power supplies are a leading brand considering their high reliability and stable operation due to their complete protection functions, long lifespan, small and space-saving design, and 2G anti-vibration capability (range of 10-500Hz) along all three axes, which ensures compatible performance in expected conditions at an affordable price.
