DESCRIPTION:

The Professional Sound Corporation PowerMax power distribution system has
been designed and built specifically to provide clean, quiet power for your
complete digital audio recording package. This new design easily handles the
heavy power requirements of today’s digital recorders and mixers. When
connected to one or two sealed lead acid batteries it can output 12Vdc at up to
12 amps continuous, as well as 18Vdc to power your audio mixer and wireless
receivers. In addition, the PSC PowerMax outputs 6Vdc for use in powering
consumer RDAT’s, small video monitors and other equipment. The PSC
PowerMax contains a high capacity, on board battery changer that is designed to
operate from 100 to 240Vac for worldwide operation. Each of the PSC
PowerMax’s six output connectors contains dedicated EMI/RFI output filters to
ensure clean, noise-free power for your equipment.

CHARGING:

The PSC PowerMax contains a built in charger designed to charge up to two
external Sealed Lead Acid (SLA) batteries. That means you can connect either
one or two separate SLA batteries such as pelican battery boxes to the
PowerMax. The PSC PowerMax will operate from 100 to 240Vac so you can
plug it in anywhere worldwide without adjustment or modifications. The changer
circuits used in the PowerMax have been specifically designed for charging the
batteries while the batteries are in use powering low noise audio equipment.
Unlike most battery chargers, ours have a very low noise floor. Using a typical
33amp/hour SLA battery you expect a recharge time of 4 hours. When using two
33amp/hour SLA batteries, you can expect a recharge time of 8 hours. The
charging function is automatic and thus, it does not require your assistance in
any way. Simply plug the PSC PowerMax into any AC outlet and the charging
begins. Beware that the heat-sink top of the PowerMax may get hot during use.
Do not touch this surface and be sure to allow at least a one-inch air gap above
the heat-sink surface for proper heat dissipation.

Because the PSC PowerMax is equipped with a high capacity charger, care must
be exercised in the type and condition of batteries to be charged. The PowerMax
is designed to charge Sealed Lead Acid (SLA) batteries only. Additionally, it is
recommended that you inspect your batteries monthly for any signs of damage
such as case cracks, leaks or bulging cases. Do not connect the PSC

PowerMax to batteries that are damaged, or beyond their recommended life
span. Failure to heed this warning could result in product damage and/or

personal injury. Bulging battery cases are a sure sign of a damaged battery
and/or shorted battery cell. Charging a battery in this condition can result in
excessive heat build up and battery venting (hydrogen gas discharge).

The PSC PowerMax is designed for use with Sealed Lead Acid batteries. These
batteries do not have the memory effects associated with NiCad batteries and
