Product Description
POWER MODULAR is SMPS based highly efficient unit that provides option of 48V/24V outputs. The output detection is auto-sense based, which automatically provides correct o/p voltage to the port where corresponding load is connected.
The modular design allows step-by-step increase of current capacity by adding modules.
A subrack supports up to a total of 4 plug-in Modules.
