Owner's Manual

Connecting the P100A Power Supplies
Caution: Make all connections before you connect the power supply to AC power
1. Assure that the device requiring power is turned off
2. Assure that the power supply switch is turned off
3. Assure that the Master/Slave switch is set to Master (see instructions below for
trapping multiple supplies)
4. Set the output voltage selector to the required voltage (13.5 volts for most car
electronics)
5. Connect the volt meter if you will be using it
6. Connect the Positive, and then the Negative power cables from the device to the
power supply. USE Extreme Caution and assure that the positive and negative
power connections are correct, as reversing polarity may well damage both the
power supply and the device being powered. The connected device should be
fused as per the manufacturer's recommendation
7. After double checking items 1~5, connect the A/C cord to a correct standard 110B
or 220I power receptacle, depending on the power supply model
8. Flip the power switch to the ON position and the blue LED will light to indicate the
powered up condition
Notes on the Operation of the P100A Power Supplies
Master/Slave Switch: When using a single P100A supply, the Master/Slave switch must
be set to Master or the Supply will go into protect and the red LED will light.
Included Volt Meter: Your package include a panel mount volt meter. You can plug the
meter's cable into the Volt Meter port in the supply's control end plate.
Temperature Controlled Fans: The fans will stay off until temperatures reach 50⁰C (120⁰F),
when they begin to cool the unit. If the temperature should ever exceed 75⁰C (167⁰F)
the unit will go into thermal protection until the unit cools to operating temperature.
Over Current: If the device connected requires more than 16Volts, or more than 100
Amps of current to operate, the power supply will sense this and go into protect and
the red protect LED will light.
