The AC / DC power supplies of the GW Instek ASR-2000 series are suitable for system integration or desktop applications. The ASR-2000 series power supplies offer nine output modes that meet your test requirements in the development of various electronic products: 
-  AC output mode (AC-INT mode) 
-  DC output mode (DC-INT mode) 
-  AC / DC output mode (AC-DC-INT mode) 
-  External AC signal source mode (AC-EXT mode) 
-  External AC / DC signal source mode (AC-DC-EXT mode) 
-  External AC signal overlay mode (AC-ADD mode) 
-  External AC / DC signal overlay mode (AC DC-ADD mode) 
-  External AC signal synchronization mode (AC-SYNC mode) 
-  External AC / DC signal synchronization mode (AC DC-SYNC mode) 
 The GW Instek power supplies of the ASR2000 series offer you a simulation mode with which you can simulate power failure, voltage rise, voltage drop and frequency fluctuations. 
 You receive the power supplies of the ASR-2000 series both as a 3 U ½ rack-mount and as a desktop model and both with an output capacity of 500 VA or 1,000 VA.
