Iso-DAM is optically
isolated so no significant current can flow from input
terminals of the preamplifier to ground. The instrument is
intrinsically safe and cannot cause any electrical
stimulus or shock to the subject. Noise from ground loops
is eliminated. Iso-DAM’s small-box structure allows the
instrument to be placed close to the site of measurement.
The front stage of this device is battery powered by six
AA Ni-Cd batteries (included). Running time after full
charging is about seven days. Power for the output stage
is supplied by a compact wall power unit, which also
charges the Ni-Cd batteries when the amplifier is not in
use. Up to four units may be daisy-chained with power
jumper cables, drawing power from a single AC adapter.
Iso-DAMs can be configured in groups of four in a
convenient rack Mount. Two units may be powered with Power
Jumper Cable #13246.
