The PowerMax Ultra™ 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 either 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 100Vac to 240Vac 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 from the front panel Bi-color LED's. A green LED indicates proper operation, a red LED, indicates a tripped Polyfuse (overload condition).
