Device Family
Indicated 30 Watt Regulated DC/DC Converter
Model Number
Selected from Table of Electrical Characteristics
Where:
xx = Input Voltage
y = Number of Outputs (Single “S”, Triple “T”)
zz = Output Voltage
Shell Connection
(C,F,M,N,P) refer to NOTES.
Remote On/Off Logic
Positive Logic - No Number
Negative Logic - 1
NOTES:
A “C” designator indicates the aluminum shell is connected internally to the common
output return pin.
An “F” designator indicates the aluminum shell is floating and is not connected to any
part of the converter circuitry.
An “M” designator indicates the aluminum shell is connected internally to the main
output return pin.
An “N” designator indicates the aluminum shell is connected internally to the negative
input voltage pin.
A “P” designator indicates the aluminum shell is connected internally to the positive
input voltage pin.
