Product Overview

The Sorensen SGI60-167 is a Programmable Precision High Power DC Power Supply that is designed for exceptional load transient response, low noise and high power density which is enhanced by a stylish front air intake allowing supplies to be stacked without any required clearance between units. The SGI60-167 combines onboard intelligent controls with outstanding power electronics.  Looping of sequences makes the SGI60-167 ideal for repetitive testing. 

Features of the Sorensen SGI60-167 Programmable Precision High Power DC Power Supply include:

• 10kW in a 3U chassis providse high power density
• Wide voltage range of 0-60V and 0-167amp
• Fast load transient response provides protection from undesired voltage excursions
• Low RMS and P-P noise for very sensitive applications
• Parallelable up to 150 kW making it expandable as requirements increase
• Upgradeable modular design
• Sequencing allows programming custom waveforms
• Easy-to-read fluorescent display supports 8 languages
• Context sensitive soft keys
• Front panel keyboard
• Onboard intelligent controls enable sophisticated sequencing, constant power mode and save/recall of instrument settings
• Precise control with 16-bit Resolution, optional IEEE-488.2, RS-232C, and Ethernet 

Specifications of the Sorensen SGI60-167 Programmable Precision High Power DC Power Supply include:
