THE L SERIES FROM WALL INDUSTRIES
The L Series features a low profile package of 2.0 x 2.0 x
0.40” with output power to 7.5watts. This series has excellent
line and load regulation, input filtering, and low output ripple,
as well as low input reflected ripple. Specifications include
high I/O isolation (500VDC), low output ripple (<50mV P-P)
and current limiting/thermal shutdown.
TO 7.5 WATTS
