Kollmorgen S30301-NA

Kollmorgen S30301-NA

Product Introduction
S30301-NA is the US order code for the SERVOSTAR 343, a 5A RMS digital servo amplifier from Kollmorgen’s SERVOSTAR 300 (S300) family. The “-NA” suffix indicates the standard version without a built-in expansion card. It belongs to the 230V to 480V voltage class (types S3xx0) and provides a balanced combination of current capacity and high-voltage operation for mid-range servo applications.
