PARSTAT 4000 External Current Booster Connections 
 
 
General 
 
This add-on option consists of a specially configured bipolar power supply from 
KEPCO®, Inc., an internal (inside PARSTAT 4000 chassis) Princeton Applied Research 
Current Booster Interface, and cabling. 
 
NOTE: The PARSTAT 4000 is factory configured and calibrated to operate with the 
bipolar power supply purchased with the option.  Using a different power supply 
could damage your system.  Before using a different KEPCO with your PARSTAT 
4000 with booster option, contact your local Princeton Applied Research representative 
or service center 
 
All experiments are computer-controlled via the VersaStudio software which correctly 
scales the current entry and measurement. No correction factor is required as with 
some other power booster options. 
 
The PARSTAT 4000 functions on a fixed current range of 2mA when operating in 
“Booster Mode” with the KEPCO power supply.  The interface board scales the current 
signals from the KEPCO to allow current measurements to ± 20 amps. 
 
The system frequency response has been modified in booster mode to provide stability 
for the complete closed-loop response for electrochemical cells with a very high 
capacitance and very low resistance. 
 
Connections and settings are identical among the three external power booster options.   
 
The power booster interface operates in power-boosted or normal modes --- a simple 
cable connection and flip of a switch convert between the two modes.  This section 
discusses the boosted mode only.
