Power supply function
and description

The PS2A200 power supply provides the high-
current capability required for such electrophoresis
applications as tank and semidry electrotransfers.
The backlit liquid crystal display (LCD) reports
power supply status, and displayed parameters are
set by pressing the keys indicated by raised dots
and arrows on the power supply face. Two pairs
of recessed output jacks accept 4 mm plugs, which
are connected in parallel.
