SGA200/25E Datasheet Supplemental Document
As part of the Sorensen SG Series, the SGA200/25E DC Power Supply, 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, 3½ digit LED readout plus front panel over-voltage protection (OVP) preview/adjustment and reset.

  • High Power Density
  • Wide Voltage Range
  • 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
Sorensen SGA200/25E Specs
Remote Sense Load-line loss compensation for models <= 100 V is 10% above full scale voltage total (5% per load-line), and models > 100 V is 4% above full scale voltage total (2% per load-line).
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)
