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.
