PSU Series User Manual

Remote monitoring 
  Voltage monitoring (VMON) and current 
monitoring (IMON) should be performed on 
both units. 
  The VMON voltage represents the voltage of 
that particular unit.  
Remote Sense 
  Please see the voltage sense chapter for details, 
page 61. 
External Voltage and Resistance Control  
  Voltage/Resistance controlled remote control 
should be used on both units separately. 
  The full scale voltage (in series) is equivalent to 
the maximum external voltage or resistance. 
Slew Rate 
  The slave rate should be set for both units. 
Internal Resistance 
  The internal resistance should be set for both 
units. 
Bleeder Control 
  The bleeder resistor setting should be set 
equally on both units. 
When using analog control connector to program 
or measure with PSU power supplies connected in 
series, make sure that each unit is separated and 
floating from each other. 
When PSU power supplies are connected in series 
and the load or one of the output terminals is 
grounded, no point on the output shall be more 
than ±600VDC above or below chassis ground.
