TD-CPU-192 Technical Specifications
Universal controller for Telcodium High Ef ciency Modules
FEATURES
• Low profile, small size
• Vertical or horizontal mount
PRODUCT OVERVIEW
The Telcodium CPU module integrates the software
required to manage all the functions of a all
Telcodium High Efficiency Modules. Both input and
output current and voltage, are monitor by the CPU,
the led, sensor and fan are also monitor by the CPU and
this information are available with the PMBUS interface
to the optional redundant feed control (patented technology).
