volts DC. The
Super PWRgate
voltage drop is approximately one-third of a
volt.
If connecting directly to a radio or other device, you will need to install
Powerpole
®
on those cords. Modern radios use
RED
wire for positive, and
BLACK wire for negative (or common or ground). Refer to the equipment
manual if you have non-standard equipment. Plug this wire into the
Super
PWRgate
terminal marked
OUT
.
If you are connecting the output to a power strip, such as a RIGrunner, it
is recommended to use #10 wire. At least one end will need Powerpole
®
installed; the other end can wire directly to the power strip or use connectors.
Note that West Mountain Radio carries 3, 6, and 10 feet long extension
cables, #10 red and black insulated wire, with Powerpole
®
on both ends.
System Checkout
When the power supply and battery are connected, and the
Super PWRgate
is driving a radio, a quick checkout procedure should be followed:
·
Run your radio, and unplug the power supply. The radio should operate
without interruption now from the battery.
·
Plug the power supply back in, and the radio will now be powered from
the supply. If you have an ammeter on the supply it will show current.
An in-line meter, such as PWRcheck by West Mountain Radio, may be
used to measures volts, amperes, watts, ampere-hours, and watt-hours
simultaneously.
Place the PWRcheck in series with the battery to get an accurate reading of
the charge current. Unplug the load from the
Super PWRgate
to measure the
battery’s charging current. Refer to the charging circuit description to verify the
different states when measuring the charging current.
Super PWRgate Charger
The charging circuit is a four-state high-current battery charger. The charging
circuit, which is always connected to the battery, uses the power supply as the
current source. It charges the battery automatically by knowing the battery’s
voltage. It also changes charging state if the power supply goes from “off” to
“on”, following a power outage, and it also changes state if the battery voltage
drops when supplying heavy current. These conditions are interrelated to
provide proper charging automatically.
The charger is a safe battery charger. It supplies the rated current if the battery
is heavily discharged. Current drops in a smooth and progressively diminishing
manner as the battery nears full charge. Note, that the charger is a feedback
