OUTPUT OVERLOAD PROTECTION:
The PSC PowerMax Ultra is equipped with Raychem Polyfuses that
automatically reset to protect the outputs of the PowerMax Ultra and also to
provide a degree of protection to your equipment. These solid state devices act
like ordinary fuses or circuit breakers. They interrupt the flow of dangerously
high electrical current in the case of a fault condition in the equipment being
powered. The PSC PowerMax Ultra contains Polyfuses on its battery inputs, its
voltage regulators and all 36 “hot” output voltage pins. The 36 separate
Polyfuses that protect the 12 output connectors are monitored separately.
The front panel of the PSC Powermax Ultra has 36 BI-color LEDs that provide a
convenient “quick glance” for user monitoring. Under normal operation, all 36 of
these LEDs should be lit green. This indicates that there are no faults on any of
the outputs. If any one of the LEDs has switched from Green to Red then that
particular polyfuse has been tripped. Because there are individual LEDs
monitoring the individual outputs, you can easily find out which output has the
problem. For example, the LED for output number 2, has turned from Green to
Red, you now know that whatever device you have plugged into output number 2
has a problem. Also, because each of the individual outputs is individually
polyfuse protected, if any one piece of your equipment has a fault, the rest of
your sound package will continue to operate. These Polyfuses will only reset
after the fault has been removed and the Polyswitch allowed time to cool down
(approximately 30 seconds).
Please note that these output protection
devices should not trip during normal use of the PowerMax Ultra! If you
experience tripping of these devices on any continuing basis, something is
wrong and a qualified technician should check your equipment and cables
immediately. Additionally, these polyfuses are rated at 4 Amps. This may
be higher than is safe for various types of equipment. Always make sure
your individual equipment is properly fused for its own protection.
