N-IP12A2 IS A 12 VOLT DC @ 2 AMP ISOLATED POWER SUPPLY
The N-IP12A2 Isolated Power Supply is a great product for noisy MP3 players — including iPods. Only four wires needed. You feed it +12 Volts and chassis ground, and the N-IP12A2 supplies a super clean +12 Volts and ground for your accessories. The ultimate “noise filter.”
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. There is a 3-Amp fuse on the + Input Lead.
The best test to see if a system would benefit from an isolated power supply is to temporarily power the component with a small 12 Volt DC motorcycle battery. If the noise goes away and the component performance improves with the motorcycle battery, then the isolated supply should be considered. An isolated power supply is not an in-line filter. The supply actually generates its own energy and when installed correctly, acts like a small motorcycle battery that never needs to be charged.
