The PSU-PC12 provides two outputs. The primary output is +12V and can provide up to 6.3 amps
(75 Watts). The secondary output is +5V to power USB devices (such as the Audigy 2NX sound
USB sound card) with up to 3 amps (15 Watts). The PSU-PC12 can accept battery input as low as 7
volts under full load (90 watts) during cranking while providing a well-regulated output so that your
