Master/ Slave operation of the SM3300 series

This interface card enables parallel or series operation of the SM3300 series, while ensuring optimal dynamic response, swift reaction times ranging from 100 to 200 microseconds, and the potential for high-speed operation in Master/Slave parallel configurations. Additionally, built-in safeguards prevent exceeding of maximum total voltage.


Functionality-wise, multiple power supplies seamlessly integrate to function as a single cohesive system, with all information visible on the master unit. Up to 8 units can operate in M/S configuration. Easily pluggable by users on-site. For more information, consult the data-sheet and manual in the downloads section.
