range of AC or DC power so you can plug it in anywhere in the world without
having to worry about making adjustments. The charger circuit used in the
Power Star has been specifically designed for charging the batteries while the
batteries are in use powering low noise audio equipment. Unlike our competitor’s
battery chargers, our design has a very low noise floor. Using a typical
33amp/hour SLA battery you can expect a recharge time of about 2.5 hours. The
charging function is automatic and it does not require your interaction in any way.
Simply plug the PSC Power Star into an AC outlet, and the charging begins. A
front panel mounted BLUE LED indicates AC is on and charging is possible if a
battery is connected. The Power Star may get warm during use. Be careful when
touching the surface of the Power Star and be sure to allow a minimum of a 1” air
gap around the top panel mounted ventilation slots for proper heat dissipation.
The PSC Power Star is designed primarily for use with Sealed Lead Acid
batteries. These batteries do not have the memory effects associated with
NiCad batteries and unlike NiCads, SLA battery life expectancy is based on how
deeply it is discharged, how long it is left in that condition and the number of
discharge cycles. If you want to get the greatest life from your SLA batteries, you
should keep them charged at all times. This is easily accomplished with the PSC
Power Star as it can be used while charging. The PSC Power Star has a built in
Voltage meter that allows you to visually see the remaining battery capacity at a
quick glance. The Power Star is also designed to protect your batteries from
over discharge. When your battery voltage drops to a pre-determined level
(approximately 10.8Vdc) the Power Star will automatically shut itself off and
disconnect the load from the battery. You cannot over discharge your batteries
from misuse or by accidentally leaving your equipment on over a weekend, etc.
Because the PSC Power Star is equipped with such a high capacity charger,
care must be exercised in the type and condition of batteries to be charged. The
Power Star is primarily designed to charge Sealed Lead Acid (SLA) batteries.
Additionally, it is recommended that you inspect your batteries weekly for any
signs of damage such as case cracks, leaks or bulging cases. Do not
connect the PSC Power Star 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 and/or explosion). While charging, the sealed lead acid batteries
should only get slightly warm to the touch. If they get very warm or hot,
something is wrong and charging should be discontinued immediately and the
batteries should be inspected by a qualified technician.
When used with one 12V, 33AH Pelican style battery and no AC power
connected, your battery only run time may be anywhere from 2 to 6 hours
depending upon your equipment’s power requirements. When connected to AC
power, your run time is virtually limitless. We highly recommend that you use
