The HiSmart US-400-24 is a slim-type switching power supply designed to provide a stable 24V DC output with a maximum current of 16.5A and a total power capacity of 396W. Engineered for efficiency and reliability, this unit operates in pulse mode to deliver consistent power for various electronic and lighting systems. Its compact aluminum housing and lightweight design facilitate easy integration into space-constrained environments, while the passive cooling system ensures quiet operation without the need for internal fans.
Advantages
This power supply unit offers high operational efficiency of up to 92%, which helps minimize energy waste and heat generation during continuous use. The robust aluminum shell provides excellent durability and effective heat dissipation through free air convection. With built-in protection mechanisms against short circuits and overloads, the device ensures the safety of connected equipment. Its slim profile makes it particularly suitable for installations where space is limited, such as behind signage or within narrow control cabinets.
Suitable for
- LED lighting systems
- LED luminous subtitles
- LED mobile signage
- Industrial automation equipment
- Electronic control systems
When it may not be suitable
This power supply is designed for indoor use and is not waterproof, so it should not be installed in environments exposed to rain, high moisture, or direct water contact. It is also not intended for applications requiring variable voltage output or high-frequency switching environments outside of its specified input range.

How to use
Installation should be performed by a qualified professional. Connect the AC input wires to the corresponding terminals, ensuring the input voltage matches the 200-240V range. Connect the DC output wires to your LED or electronic device, observing correct polarity. Ensure that the total load does not exceed the rated 396W capacity. The unit relies on free air convection for cooling, so it must be mounted in a location with adequate airflow and sufficient clearance around the housing to prevent overheating.
What to consider before purchase
- Verify that your total load does not exceed 396W.
- Ensure the installation environment is dry and well-ventilated.
- Check that the input voltage matches your local power grid.
- Confirm that the physical dimensions fit your intended mounting space.
Usage recommendations
For optimal longevity and performance, it is recommended to operate the power supply at approximately 80% of its maximum rated capacity. Ensure that the ventilation holes are not obstructed by dust or debris to maintain efficient heat dissipation.
