MEAN WELL RSP-320-5 Switching Power Supply 300W 5V 60A

MEAN WELL RSP-320-5 is a high-performance 5V power supply designed for versatility and reliability. This compact unit delivers 300W of power with a rated current of 60A, making it ideal for applications requiring high current in a slim form factor.

Its universal AC input (88-264VAC) and built-in active PFC function (PF>0.95) ensure global compatibility and efficient power usage.Key features include comprehensive protections against short circuits, overloads, over-voltage, and over-temperature conditions.

The unit employs forced air cooling with a built-in DC fan and speed control, maintaining optimal operating temperatures in a low-profile 30mm height design.

With an adjustable voltage range of 4.5-5.5V, low ripple (150mVp-p max), and excellent load regulation (±1.0%), the RSP-320-5 offers precise power delivery. It boasts UL60950-1 and TUV EN60950-1 safety approvals, along with EMC compliance for both emissions and immunity standards.

Backed by a 3-year warranty and featuring an LED power indicator, this power supply combines durability, performance, and user-friendly design for demanding industrial and commercial applications.

Note 

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25 of ambient temperature.

2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.

3. Tolerance : includes set up tolerance, line regulation and load regulation.

4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives.

5. Derating may be needed under low input voltages. Please check the derating curve for more details. ¢J For guidance on how to perform these EMC tests, please refer to EMI testing of component power supplies.
