Introduction 

 

Floating DC supply voltages 

 

DC : 0 - 30V; 0-2 Amp 

 

Constant voltage & constant current operation 

 

Digital display for voltage and current 

 

Adjustable current limiter 

The 

ST4073  30V,  2A  Power  Supply

  has  been  designed  as  a 

constant  current  (CC)

 

and 

constant  voltage  (CV)

  source  for  laboratories,  industries  and  field  testing 

applications, featuring low power loss, compact and light weight. It provides floating, 
DC output voltages and is ideally suitable for complex analog and digital applications. 

The  DC  output  can  be  continuously  adjusted  from  0  -30V  with  coarse  and  fine 
controls.  Current  limit  is  also  adjustable  from  0-2A.  Any  over  loading  for  adjusted 
current  limit,  is  indicated  by  flashing  "CC"  LED.  When  the  maximum  setting  is 
crossed or the overheating has occurred, the LED will lit up. 

A  3-digit  display  for  voltage  and  current  is  used  to  read  the  instantaneous  values. 
These  two  parameters  are  switchable  for  indicating  either  voltage  or  current.  In 
addition to low residual ripple and noise, it has excellent line and load regulation. The 
30V- 2A Power Supply is also provided with all  protective circuits to ensure trouble 
free operation.
