Q. How much clearance do I need to provide from the honeycombed surfaces when designing an enclosure for the LS25-12
A. Hi Mike, thank you for your question. This Chassis Mount Power Supply is not suitable for wall or bench mounting. This must be used in open air.

Very capable & compact power supply. Adjusted for 12.5V output and followed by a low dropout linear regulator in our application. Produced 12V @ 2A with very low noise.
