DESCRIPTION:
The Professional Sound Corporation PowerMax Ultra 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
30 amps continuous, as well as 15 to 18Vdc (internally adjustable) to power your
audio mixer and wireless receivers. In addition, the PSC PowerMax Ultra
outputs 5 to 9Vdc (internally adjustable) for use in powering consumer digital
recorders, small video monitors and other equipment. The PSC PowerMax Ultra
contains two high capacity, on board battery chargers that are designed to
operate from either 100Vac to 240Vac or from 127Vdc to 370Vdc for worldwide
operation without adjustment. Each of the PSC PowerMax Ultra’s 12 output
connectors are equipped with dedicated EMI/RFI output filters to ensure clean,
noise-free power for your equipment. In addition, each of the 12 output
connectors are individually Polyfuse protected and is monitored for proper
voltage output and over current faults. The status of all of these monitors can be
viewed form the front panel BI-color LEDs. A green LED indicates proper
operation, a red LED, indicates a tripped Polyfuse (overload condition).
CHARGING:
The PSC PowerMax Ultra contains two built in chargers designed to charge up to
two external Sealed Lead Acid (SLA) batteries. That means you can connect
either one or two separate SLA batteries to the PowerMax Ultra. These batteries
can be 12V. 33AH Pelican battery boxes or large Deep Cycle batteries such as
Optima Yellow Top batteries. The PSC PowerMax Ultra will operate from a wide
range of AC or DC power so you can plug it in anywhere world without having to
worry about making adjustments. The charger circuits used in the PowerMax
Ultra 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 about 2.5 hours. Because of the two
independent onboard chargers, when you are using two 33amp/hour SLA
batteries, you can expect the same recharge time of about 2.5 hours. The
charging function is automatic and thus, it does not require your assistance in
any way. Simply plug the PSC PowerMax Ultra into an AC outlet, turn on the AC
rocket switch located on the left side of the front panel and the charging begins.
Beware that the PowerMax Ultra may get warm during use. Be careful when
touching the surface of the PowerMax Ultra and be sure to allow ventilation air
gaps around the top panel mounted ventilation fans and also around the sides of
the Powermax Ultra for proper heat dissipation.
