Owner's Manual

Using Multiple Power Supplies

Up to four P100A power supplies can be strapped to provide more DC current if

required by the powered device. Each supply will add 100 Amps to the circuit for a max-

imum of 400 Amps. The first supply in such a circuit must be set to Master. All following

supplies are set to Slave, then the Master supply's voltage control will set the voltage for

all the supplies.

See above: Using the supplied connecting cables, the control OUT of #1 goes to the IN

of #2. OUT of #2 goes to IN of #3, etc. Only Supply 1 is in Master mode, all others are in

Slave mode.

Interference: The Zapco power supplies are high power switching supplies and as such

may cause some interference to TV or radio reception. If you experience this you should

turn the power supply off and move it further away from the receiving device. Correct

Input Voltage: Your P100A supply is set for to the proper input voltage for the country in

which it was first sold. If you should move or need it changed for some other reason,

you may contact your Zapco Dealer of Zapco directly about modifying your unit.

Using Power Supplies with Batteries

The Zapco power supplies can be used in combination with a battery or batteries,

depending on the usage requirements. Batteries should be 12 volt automotive type.

Higher voltage commercial batteries should not be used and will put the supply into

protection. Multiple batteries must be connected in parallel.

For safety, there should be a 100A fuse at the output of the power supply and a fuse of

manufacturer's recommended amperage at the amplifier.
