What Stands Out
High Output Power
With 275W and 55A output, the Mean Well SP-320-5 delivers powerful performance, ideal for driving high-demand LED signs and ensuring efficient operation without compromise on brightness.
Stable Voltage
The power supply maintains a consistent 5V output, reducing flicker and enhancing the lifespan of your LED fixtures, providing reliability for demanding signage applications.
Compact Design
The compact form factor of the SP-320-5 allows for easy installation in tight spaces, making it an excellent choice for various LED installations where space is a constraint.
