## Long description

The MEAN WELL HRP-300-12 is a reliable power supply unit delivering a total power of 324W designed for continuous and efficient electrical conversion. Operating within an AC input voltage range of 85V to 264V and supporting a frequency range of 47 to 63 Hz, this unit accommodates a universal power input to suit various electrical environments. It features active cooling with one built-in fan and a built-in cooling fan ON-OFF control mechanism to manage thermal performance effectively. Built with safety and compliance in mind, the unit meets recognized standards and includes a 1U low profile design measuring 105mm in width, 199mm in depth, and 41mm in height.
Advantages
This power supply unit stands out with its high efficiency rate of up to 89 percent, which helps minimize energy losses during operation. The incorporation of a built-in active power factor correction function with a power factor greater than 0.95 ensures optimized power utilization. For enhanced resilience, the device can withstand a 300VAC surge input for up to 5 seconds, protecting the internal circuitry from unexpected grid fluctuations. Comprehensive safety is provided through built-in protections against short circuits, overloads, over voltages, and over temperatures, complemented by a constant current limiting circuit. Additional integration capabilities include a built-in DC OK signal and a remote sense function for precise voltage delivery.
Suitable for
Industrial automation systems requiring stable 324W power
LED lighting installations and large display setups
Control panels and machinery with 1U low profile space constraints
Electronic test equipment and laboratory setups
When it may not be suitable
This device may not be suitable for environments that require completely silent operation, as it utilizes active cooling with a built-in fan that generates operational noise. Additionally, applications operating outside the specified voltage range or those requiring water-resistant enclosures will need alternative power solutions.
Key specifications
Total power output: 324W
AC input voltage range: 85-264V
Frequency range: 47-63 Hz
Efficiency: Up to 89%
Dimensions: 105mm width x 199mm depth x 41mm height
Cooling: Active cooling with one built-in fan
Certifications: UL60950-1 and TUV EN60950-1
How to use
Installation should be performed by qualified personnel in accordance with standard electrical safety guidelines. Ensure that the input voltage matches the specified range of 85 to 264 volts AC before connecting the wiring to the designated terminals. Mount the unit securely within an enclosure or rack that allows adequate airflow for the active cooling fan. Connect the load to the output terminals, observing correct polarity, and utilize the built-in remote sense and DC OK signal connections if required by your specific system architecture.
What to consider before purchase
Verify that the 324W power output matches the total electrical load requirements of your application
Check the physical dimensions of 105mm x 199mm x 41mm to ensure it fits within your available mounting space
Account for the active cooling fan noise in acoustically sensitive environments
Confirm that input voltage sources align with the 85-264V operating range
Usage recommendations
For optimal longevity and safety, ensure proper ventilation around the unit to allow the active cooling fan to function efficiently. Avoid obstructing the airflow paths and periodically check terminal connections to maintain secure electrical contact.
