THE SI SERIES FROM WALL INDUSTRIES
The SI Series features a single case size (2.56 x 3.0 x
0.84”) for every unit - 15 to 30 watts. Specifications
include remote on/off, short circuit protection, Pi input fil-
ter, over-voltage protection and excellent line and load
regulation. SI Series units operate at case temperatures
from -25 to +85°C with no derating. Metallic case provid-
ed for shielding.
SPECIFICATIONS: SI SERIES
All specifications apply @ +25 C ambient unless otherwise
noted.
