Product Description
CB1.1
These products are component switch-mode power supplies intended to be built into an end
product. Input/output connectors are provided for factory wiring in the end use equipment.
CC1.0
Model Differences
CC1.1
All models within the Model Series GEM600 are similar with exception to the Main Power
Transformers and minor component changes.
All models within the Model Series GEM750 are similar with exception to the Main Power
Transformers and minor component changes.
Model Series GEM600 and GEM750 are nearly identical to each other with exception to the
difference to the Power FETS, which are more robust in the GEM750 Series.
Models GEM600-VV-WXY-ZZ G and GEM750-VV-WXY-ZZ G have following nomenclature
differences:
Where VV is the output Voltage 24-48VDC
W is an alpha character A or T, which represents the Input Connector
X is an alpha character A, B or T which represents the Output Connector
Y is an alpha Character D, which represents the Optional OR-ing Diode
-ZZ is any numeric character 00-99 which represents Value Added Configurations not related to
safety
"G" indicates the manufacturer's claim of compliance with the RoHS directive
