THE LW SERIES FROM WALL INDUSTRIES
The LW Series is a family of ultra wide input voltage range
(4:1), highly efficient, 15 watt DC/DC converters. Features
include a pi-input filter to reduce input reflected ripple, con-
tinuous short circuit protection with over-temperature shut-
down and 500 VDC (minimum) input/output isolation. The
LW Series is ideally suited for any telecommunications, auto-
motive test equipment, process control, minicomputers, or
geosurvey equipment applications demanding variable input
voltage ranges and high reliability.
