Sorensen SGA75-266

SORENSEN SGA75-266 DC Power Supply (call for availability)

The Sorensen SGA75-266 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 units.

The Sorensen  SGA75-266 DC Power Supply (SGA = Sorensen General Purpose Analog), with its high performance power electronics, meets the need for simple front panel analog controls or external control. It provides essential features like 10-turn potentiometers for setting voltage and cur, 3 ½ digit LED readout, plus front panel over-voltage protection (OVP) preview/adjustment and reset.

Features and Specifications of the Sorensen SGA75-266 DC Power Supply include:

High Power Density: Up to 20 kW

Wide Voltage Range: 0-75V up to 0-266V, in increments of 3 kW from 5 to 20 kW

Fast Load Transient Response: Protection from undesired voltage excursions

Low RMS and P-P Noise:  Suitable for the most sensitive applications

Parallelable up to 150 kW: Expandable as your requirement grows

Modular Design: Upgradeable for the ultimate in investment protection

16-bit Resolution:  Optional IEEE-488.2 + RS-232C + Ethernet provides precise control

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
