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.

SPECIFICATIONS: L SERIES

All specifications apply @ +25 C ambient unless

otherwise noted.
