West Mountain Radio Operating Manual

Choosing a Mounting Location

Pick a location that is close or central to the power supply, battery,

as well as the load or 12V distribution panel. Radios and many 12V

devices draw large amounts of current. All wires have resistance, so it

is good practice to keep them as short as possible and to use a larger

gauge wire to minimize voltage drop.

The PG40S can be installed in any orientation. It is recommend to

use in a cool dry location and preferably well ventilated. Do not tightly

enclose the unit as the heat sink can become quite warm under

maximum current. At 40A continuous current it will rise about 40

degrees Fahrenheit over ambient temperature in free air. If placed in

direct sunlight, it will absorb heat and get unnecessarily hot.

The Super PWRgate can be mounted using number 8 hardware in the

two mounting holes.

Please read the following instructions

BEFORE installing the PG40S

The PG40S transfers 40 amperes at 12 volts DC in a continuous safe

manner. It connects a battery and a power supply to a load, while

electrically isolating both the battery and the supply from each other.

Whenever the power supply is on, the supply feeds the load. It also

charges the battery with a high-current four-state safe battery charger.

Whenever the power supply is off, the battery will feed the load. If either

the power supply or the battery is malfunctioning, neither draws current

from the other. The switching is instantaneous.

A PG40S is very useful in the ham shack, and even more useful in a

repeater installation. Communication equipment will remain operative

during AC power blackouts and power supply failures. Power supplies

and batteries can be swapped out while equipment continues to be

powered and without glitches.

Additionally, the PG40S and a power supply may be used solely as a

permanently installed battery charger. This also may be congured to

run a radio station directly from the battery. (See the article by W1ZR in
