Product information

Description

The MEAN WELL RSP-320-15 is a high-performance 321W power supply unit engineered for demanding industrial environments. Featuring a compact 1U low-profile design with a height of only 30mm, this unit is optimized for space-constrained installations. It supports a universal AC input range from 88V to 264V and incorporates an active power factor correction (PFC) function to ensure efficient energy utilization. With a robust build quality and a high MTBF of 206,500 hours, it provides consistent and reliable power delivery for various electronic systems.

Advantages

This power supply unit offers exceptional efficiency reaching up to 90%, which helps in reducing heat dissipation and operational costs. The inclusion of an active PFC function with a power factor greater than 0.95 ensures compliance with power quality standards. Its low-profile 1U form factor allows for seamless integration into standard rack-mount systems or tight enclosures. Furthermore, the integrated cooling fan maintains optimal operating temperatures, while the built-in LED indicator provides immediate visual confirmation of the power status.

When it may not be suitable

This unit is designed specifically for industrial and professional electronic applications and may not be suitable for consumer-grade home appliances or environments requiring silent operation, as the built-in cooling fan generates audible noise. It is not intended for outdoor use unless housed in a protective, weather-resistant enclosure.

  • Active PFC: Built-in (PF > 0.95)
  • Safety standards: UL60950-1, TUV EN60950-1

How to use

Installation should be performed by qualified personnel. Connect the AC input lines to the designated terminals, ensuring the voltage matches the specified range. Secure the unit to a flat surface or chassis using the mounting holes provided, ensuring adequate airflow around the cooling fan intake and exhaust. Connect the DC output to your load, observing correct polarity. Verify the connection by checking the LED indicator after powering on the device.

What to consider before purchase

  • Verify that the 15V output matches the requirements of your specific equipment.
  • Ensure the installation environment provides sufficient ventilation for the cooling fan.
  • Check if the physical dimensions fit your intended mounting space.
  • Confirm that the total power consumption of your system does not exceed the 321W limit.
