Matching the supply to the load
The 3A rating makes this a different choice from higher-current 5V supplies used for larger LED loads. Use the load specification and the temperature derating curve to determine whether this model has sufficient capacity.
The specification PDF provides the terminal layout, mounting drawing and operating conditions. Allow ventilation around the enclosure when installing it.
Frequently asked questions
What is the output of the RS-15-5?
It is rated at 5V DC, 3A and 15W.
How large is the RS-15-5 enclosure?
The manufacturer specifies 62.5 × 51 × 28mm, in length × width × height order. Check the PDF drawing for mounting details.
Is it suitable for every 5V LED screen?
No. The connected equipment must match the voltage and stay within the available current and thermal limits. Check the total load before choosing a 15W supply.
Does it need a cooling fan?
The supply uses free-air convection. Its enclosure still needs ventilation and must be installed within the datasheet operating conditions.
