Overview  Sorensen SGI Series 
1-2  M550221-01 Rev U 
 
For units up to 999 V/999 A, voltage and current are represented in numeric format, e.g., “100” 
represents 100 V. For units at 1000 V/1000 A and above, the voltage and current are 
represented by the format “xKx”, e.g., “1K0” represents 1000 V.
