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.

NOTES:
1. All case and pin to case dimensions reference only
unless otherwise noted.
2. All DC/DC converters should be externally fused for pro-
tection.
3. Significant capacitive load may impact start-up and oper
ation, consult factory.
4. For Remote On/Off, add “R” to end of part number.
Available on triple output units only.
