Note: The four pairs of output
jacks always operate at the
same voltage.
The sum of the current of all four
outputs is displayed. This value
can never exceed 2.0 A.
Power supply function
and description
The Hoefer ® PS200HC power supply provides
the high current capability required for such elec-
trophoresis applications as standard- and large-
format tank and semidry electrotransfers. It is
also suitable for all mini-vertical gel electropho-
resis, most standard vertical gel electrophoresis
applications and submarine gel electrophoresis.
The LED display reports current status. Param-
eters are set by pressing UP/DOWN arrow
buttons in combination with a SELECT button.
Four pairs of output jacks accept 4 mm plugs,
which operate in parallel. The output jacks are
color coded, recessed for safety, and accept 4 mm
shielded (banana) plugs that come standard with
most Hoefer equipment.
The user interface consists of a three digit,
LED readout, and five buttons on a membrane
keypad. Diagrams of the front and rear panel
are shown on the following pages.
The PS200HC operates in constant voltage or
constant current modes. Output is controlled
by setting a maximum value for voltage (up to
200 V), or current (up to 2.0 A). The maximum
power output is 200 Watts. Run duration can be
continuous or programmed to a maximum dura-
tion of 999 minutes.
