Description: "The N-IP12A2 Isolated Power Supply supplies a regulated 13.8 Volts DC at 2 Amps from an input voltage of 9 to 16 Volts DC. The main feature of the N-IP12A2 is that output voltage is NOT connected to the input voltage. This means that as long as the load does not touch the car's chassis, the N-IP12A2 will supply a new ground reference that is clean, regulated, and free of the car's accessory noise. Uses for the N-IP12A2 include powering non-powered processors such as equalizers, electronics crossovers, DSPs, etc."
