Description
Logitek's PS-55 Series is a family of high power density, low pro-
file, 28 V
IN
DC/DC switch mode converters. This family extends
from 25 Watt through 150 Watt in single, dual, and triple configura-
tions. The PS-55 Series is ideally suited for airborne, shipboard,
ground mobile and C
3
I applications. All Logitek DC/DC Converters
and Power Supplies are designed and qualified to the most stringent
performance and environmental requirements. Full-Mil units receive
ESS Screening, including burn-in and temperature cycling.
