Sorensen M51A - Post Sale Upgrade
The Sorensen DLM4k-M51A-Upg is a post-sale upgrade option for the DLM 4k Series programmable DC power supplies. This upgrade enables the M51A digital interface, which provides advanced digital communication capabilities for enhanced remote control and monitoring of the power supply. The M51A interface supports multiple protocols, including GPIB, RS-232, and RS-485, allowing for flexible integration into automated test systems and remote operation environments. This upgrade is intended for users who initially purchased a DLM 4k Series unit without the M51A interface and wish to add this functionality after the original sale. Installation and activation of the upgrade should be performed according to Sorensen's official procedures to ensure proper operation and maintain warranty coverage.
