PRODUCT DESCRIPTION
The Specialty Concepts Digital Monitor Mark III (DM3) is a
flush-mounted digital meter for monitoring the performance of
an alternative energy system. The DM3 uses a large, easy to
read, liquid crystal display, a rotary switch for selection of
voltage and currents, and indicator lights for "HIGH
VOLTAGE ALARM" and "LOW VOLTAGE ALARM". The
standard DM3 measures the battery voltage and a single
current reading of up to 30 amps. With a separate (optional)
remote shunt, an additional 100 or 500 amp current reading is
available. The internal 30 amp shunt can be cut and replaced
with a remote shunt allowing two current readings to be made
using remote shunts. The two current readings allow the DM3
to monitor a charging circuit and a load circuit that may be a
power distribution box or an invertor. An auxiliary input allows
the monitoring of a second system voltage or a third current.
An optional knock-out box (4x7 BOX) is available for wall
mounting, or to protect the DM3 for in-wall flush mounting.
Many of the features of the DM3 are user programmable and
can be easily changed in the field.
This unit operates in nominal 12 to 48 volt systems.
Electrical connections are easy to make to the back of the
unit with bare wire or with terminal lugs.
