Designed from the ground up to power your complete audio system. This power supply can provide a total of 1000W of audio power at 48Vdc making it the ideal power source for D2Audio* modules and other 48V systems. It also provides +5v, +/-12v, +3.3v for other system components including pre-amps and DSPs. A universal AC input range (90-265VAC) with power factor correction allows the P-1000-48 to work around the world. Outputs are fully protected against short circuits and over temperature conditions. Standby mode shuts off the main converter leaving the 3.3v output active for a DSP to monitor audio inputs and command turn on. It's powerful and green.
