Car Audio Amplifier Power Supply. Can be used for audio amplifiers which need Supply voltage in range of +-30V to +-72V at a current from 3.5A to 8.5A and has an auxiliary regulated differential voltage of +-12V at 500mA which can be used for preamplifier's or other stages of the amplifier. All the outputs are galvanically isolated from the input. Has remote turn on function. The input voltage should be in range of 10.4V to 15.9V DC and the output voltage is regulated, and can be one of the following values: +-30V +-36V +-42V +-48V +-54V +-60V +-72V.
