Idle Stop Power Booster

A Start-Stop or Stop-Start (Idle Stop) system automatically shuts down in many modern vehicles. It restarts the engine to lessen the time spent idling, reducing fuel consumption and emissions. The Alpine KPX-100B eliminates problems commonly seen with this technology, which can cause various voltage drops in CD Tuners and Mobile Media Stations. This can lead to the unit turning off when the vehicle cranks the engine at the traffic lights.

By detecting the vehicle's battery voltage, the KPX-100B can buffer the output voltage at 12VDC when sudden drops in the input voltage are detected. The Alpine KPX-100B is equipped with a DC/DC converter controlled by a microprocessor that continuously monitors the input voltage. In standby mode, the current bypasses the DC/DC converter. When activated by a sudden voltage drop, the DC/DC converter will engage and stabilise the output voltage to 12 VDC.

The Alpine KPX-100B is suitable for buffering a CD Tuner, Mobile Media Station, or similar product, plus a steering wheel remote control interface. It enables installations into vehicles that were previously impossible due to their restrictive technologies.
