The Sorensen SGA60X250D is a 15 kW programmable DC power supply engineered for high-demand research, development, automated testing, and industrial applications. This analog-controlled unit delivers 0–60 V at 0–250 A with exceptional load transient response and low ripple, meeting stringent precision requirements across voltage and current regulation. Built on a modular 5 kW platform, the SGA60X250D fits a 3U package while supporting parallel operation of up to 5 units for increased current capacity and series connection of up to 2 units for elevated voltage. Its high power density, flexible input compatibility, and tight regulation specifications make it suitable for demanding bench and system-level applications.
