 Référence : EP 560 000
              
               
             
      Specifications:  
  
Each branch is equipped with one insulated probe with BNC output. 
  
Chopper: 
▪ Serial 
▪ Voltage reversible 
▪ Current reversible 
▪ Four quadrants 
▪ Serial, dual mixed ( 0 +E 0 / 0 –E 0 ) 
 
Inverters: 
Single-phase 
▪ Full-wave, shifted control, fixed frequency. 
▪ Full-wave, shifted control, variable frequency. 
▪ PWM +/-E, +/0/-E. 
 
Closed loop control (linked with the EP 561 000 control console): 
▪ Speed & position servo-control of a DC motor. 
▪ Study of different correctors: P, PI, PID, cascade, state feedback, Z transform. 
▪ Generation of new correctors by integrated C compiler.... 
 
Safety devices: 
▪ Excitation current monitoring. 
▪ Protection against short-circuits (short-proof, even at full load). 
▪ Supervision of power supply: min 12 V / max 240 V before start. 
▪ Load current control of the filter capacitor when powering up. 
▪ Emergency stop if the reversible capacitor voltage exceeds 260 V.  
▪ Monitoring of the current in the discharge transistor. 
▪ Monitoring of the reversible capacitor voltage.  
▪ Monitoring of the heat sink. 
 
Control panel: 
The control panel ensures  the user's interface & the system control. 
   
Optional: 
▪ EP560200, D_CCA: Study of the servocontrol of  DC motors , 
▪ EP560800, D_Scil: Automatic generator of real time correctors with Scilab/Xcos®.
