SORENSEN SGI800-25 DC Power Supply (call for availability)The Sorensen SGI800-25 DC Power Supply is a high powered, programmable power supply designed for exceptional load transient response, low noise, and the highest power density in the industry. The power density is enhanced by a stylish front air intake allowing supplies to be stacked without any required clearance between unitsThe Sorensen SGI800-25 DC Power Supply (SGI = Sorensen General Purpose Intelligent) combines onboard intelligent controls with outstanding power electronics. These controls enable sophisticated sequencing, constant power mode and save/recall of instrument settings. Looping of sequences makes the Sorensen SGI800-25 DC Power Supply ideal for repetitive testing. An impressive vacuum fluorescent graphical display in eight languages, context sensitive “soft” keys and front panel keyboard simplify programming of the Sorensen SGI800-25 DC Power Supply.Features and Specifications of the Sorensen SGI800-25 DC Power Supply include:

Common:

Remote Sense:  Terminals are provided to sense output voltage at point of load. Maximum line drop 5% of rated voltage per line for 40-100V models, line drop 1V of rated voltage per line for 10-20V models, 1.5V for 30V models, 2% of rated voltage per line for models 160V and greater. (Greater line drop is allowed, but output regulation specifications no longer apply).

Parallel Operation:  Up to 5 units may be paralleled for additional cur within the power supply single-unit specifications, with exception of the DC output cur set accuracy. Additional paralleled SG units will add 0.3% inaccuracy per unit. To parallel more than 5 units, contact factory.

Series Operation:  Up to 2 units
