Sorensen SGI Series Modular Programmable DC Power Supply 5kW – 30kW

Description

The Sorensen SG series (hereafter SG Series) represents the next generation of high power programmable DC power supplies. The SG Series is designed for exceptional load transient response, low noise and the highest power density in the industry. With a full 15 kW available down to 20Vdc output, and 12kW at 10Vdc and 1200ADC in a 3U package, the SG leads the industry in power density. The SG provides models up to 1000Vdc at 15amps. The power density is enhanced by a stylish front air intake allowing supplies to be stacked without any required clearance between units.

At the heart of the SG series is a 5 kW power module. Depending on the output voltage, one to six modules can be configured in a single chassis to deliver 5 kW to 30 kW of power. Combinations of these chassis can then be easily paralleled to achieve power levels up to 150 kW. Paralleled units operate like one single supply providing total system current. Available in two control versions, the SGA has basic analog controls, while the SGI provides intelligent control features.

(Sorensen General purpose Analog) The SGA, with its industry leading price performance, is available for customers requiring simple front panel analog controls or external control. With the same high performance power electronics as the SGI, the SGA provides essential features like 10- turn potentiometers for setting voltage and current, 3 ½ digits LED readout plus front panel over-voltage protection (OVP) preview/adjustment and reset.

Features

  • High Power Density: up to 15 kW in 3U, 30 kW in a 6U chassis
  • Wide Voltage Range: 0-10V up to 0-1000V, from 4 to 30 kW
  • Fast Load Transient Response: Protection from undesired voltage excursions
  • Low Ripple and Noise
  • Hardware Trigger (Ethernet Option)
  • Parallelable up to 150 kW
  • Sequencing: Free system controller & speed up test
  • Low audible noise: Temperature controlled variable speed fans

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 (see Output Float Voltage)
