The Ametek/Elgar 20V Mod. Master Power Module is a DC power supply module engineered for integration into the Elgar AT8000 series programmable multi-output DC power systems. This plug-in module delivers stable 20V DC output and operates as part of a modular architecture supporting up to 16 independent channels across master and expansion chassis configurations. The module employs linear design topology for fast transient response and minimal ripple, with complete output isolation and comprehensive protection circuitry. It is controlled via IEEE-488 GPIB remote interface or front-panel keyboard, supporting MATE, CIIL, and SCPI 1995.0 programmability standards.
