Protection
The MFJ-4275MV has fault protection for output terminal short or overload
(over 75 Amps), over voltage (pre-set at 16 Vdc) and component over heated. If
any the above conditions occur, the warning LED will come on. Under fault
condition, the power supply will automatically shut off. To reset, turn the unit
OFF and wait 20 seconds, then turn the unit back on.
Battery Charger
MFJ-4275MV has built-in battery charging circuit. Battery to be charged must
be connected to the charger output binding posts on the back of the unit.
Charging output is set at 13.8 Vdc fix. Maximum charging current is 20 Amps
for 20 seconds and 5 Amps continuous. When the battery reaches its capacity
the charging circuit will reduce charging current to trickle charge at 30 mA.
Powerpole®
connector assembly
Two sets of Anderson
Powerpoles
®
connectors are provided.
The terminals accommodate wires from 12 to 16 gauge.
Follow the following instructions to assemble the connectors.
First, slide two connector housings together to match the configuration
of the corresponding connectors on your power strip. It’s easier to do
this now rather than after the wired terminals have been inserted in the
housings.
You can install the
Powerpoles
®
connectors on your wires by either
soldering or crimping, as long as you make sure you have good, solid
connections. Wires smaller than 12 gauge will
not
allow for crimping,
and must be soldered to the terminals.
To crimp, first strip the wire, making sure not to damage the wire strands.
Insert the wire into the terminal and crimp.
Be careful not to deform or
squash the terminal body
. If you do, crimp again to return it to its original
shape. Otherwise, the terminal may not fit inside the housing. Be sure that
you have a good firm connection to reduce resistance.
