FB200-2 MANUAL Page 3 7608175 Rev A 8/02
Introduction
Thank you for selecting a Fisher Scientific FB200 Electrophoresis power supply. This manual
describes the operation of the FB200. The power supply that you have purchased is the most
productive and easy-to-use unit available anywhere. This manual should answer any questions
that might arise in operating your power supply; however, don't hesitate to call our Fisher Lab
Equipment Technical Support Hotline at 1-800-943-2006 or 1-800-926-0505 if you need any
assistance.
The FB200 power supply is designed to provide constant voltage or constant current output to
apparatus used in electrophoresis applications. One to four sets of electrophoresis cells can be
connected in parallel and run simultaneously. The FB200 can deliver up to 200W of total output
power. When operating in constant voltage or constant current mode, the power supply
automatically limits the other parameter to either the power supply maximum, or a lower limit if
set by the user. If this non-constant limit is reached, the power supply will automatically switch
control modes, from constant voltage to constant current, or vice versa. In this way, the FB200
protects your electrophoresis cells from damaging over power conditions. The FB200 power
supply also provides for timed operation in either voltage or current modes, and allows an
automatic completion in the event of a power loss if enabled by the user.
