B. Introduction
EPS-200 X power supply is compact, space saving and light weight in design. It can be
used with many electrophoresis applications, such as running standard PAGE gels, multiple
PAGE mini gels, horizontal/vertical agarose gels, semidry transfer and mini-gel tank transfer.
The LED display reports power supply status. Parameters are set by pressing UP/DOWN arrow
buttons in combination with a MODE 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 both 4 mm
unshielded and shielded (banana) plugs. 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 EPS-200 X operates in constant voltage or constant current
modes. Power output is controlled by setting a maximum value for voltage (up to 200 V), or
current (up to 2 A). The maximum output power at any time is 200 Watts. The Run duration can
be continuous or programmed to a maximum duration of 1440 minutes. The EPS-200 X
automatically “crosses over” or switches the limiting parameter according to the programmed
limits as the resistance of the electrical load changes during a run.
