Product Overview

RENT SORENSEN SGA60-333 DC POWER SUPPLY (Call for Availability)

The Sorensen SGA60-333 DC Power Supply (SGA = Sorensen General Purpose Analog), is a high powered, programmable power supply designed for exceptional load transient response, low noise, and the high power density. The power density is enhanced by a stylish front air intake allowing supplies to be stacked without any required clearance between units. The Sorensen SGA60-333 with its high performance power electronics, meets the need for simple front panel analog controls or external control.
