Product Overview

RENT SORENSEN SGA800-37.5 DC Power Supply (call for availability)

The Sorensen SGA800-37.5 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  SGA800-37.5 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 current, 3 ½ digit LED readout, plus front panel over-voltage protection (OVP) preview/adjustment and reset.

Features and Specifications of the Sorensen SGA800-37.5 DC Power Supply include:

• High Power Density: Up to 30 kW in a 6U chassis
• Wide Voltage Range: 0-10V up to 0-800V, in increments of 3 kW from 5 to 30 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 current within the power supply single-unit specifications, with exception of the DC output current 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

• Frequency:  47 – 63Hz , 400Hz
• Power Factor: 
• >0.9 typical for 208/220 VAC input (10V - 800V)
• >0.78 typical for 380/400 VAC input (40V - 800V)
• >0.9 typical for 380/480 VAC input (10V - 30V)
• >0.7 typical for 440/480 VAC input (40V - 800V)
• >0.9 typical for 440/480 VAC input (10V - 30V)
• Protection:  ½ cycle ride-though on all three phases, 3 cycle ride through on single phase; missing phase shutdown (800V model 6.4 msec on all 3 phases)
