HPC-1 High Power Voltage Converter

Product Description

Aurora Design HPC-1 High Power Voltage Converter for 6V and Positive-Ground Classics

The HPC-1 is Aurora Design's power converter for cars with original 6-volt or 12-volt positive-ground systems, or 6-volt negative-ground systems. The FMR-3.2 receiver runs on 8.5-16.0V DC, so these vehicles need a separate supply, and the HPC-1 is the one Aurora Design specifies for the FMR-3.2. Aurora Design says it delivers 70% more power than competing converters, which makes both two-speaker and four-speaker installations practical.

The Problem It Solves

Owners of 6-volt and positive-ground vehicles used to be stuck with weak sound from their converted radios because available converters couldn't supply enough power. The HPC-1 can fully drive two 4-ohm speakers, or four speakers at reduced power.

Performance

• Up to 56W output from a 6V positive-ground system with the engine at fast idle
• Up to 90W output from a 6V negative-ground system with the engine at fast idle
• High-efficiency synchronous design for low power loss
• Filtered on all connections, with proprietary EMI reduction circuitry

Thanks to its filtering and EMI reduction, the HPC-1 provides a very clean output without large external filters that waste power. That matters in a classic car, where electrical noise can easily creep into AM reception.

Protection Built In

The HPC-1 has full reverse-battery and transient protection. A low-voltage lockout circuit makes sure the converter always operates properly, so a weak battery won't cause blown fuses or a damaged converter. Those protections fit the rest of the FMR-3.2 system, which is built to withstand reverse battery, load dump and double-battery jump starts.

Simple Installation

One HPC-1 board covers every installation it supports, so you don't need different versions for different vehicles. Its very small size and low EMI let it mount directly inside the converted radio, which keeps the installation tidy and hidden. There's no separate box under the dash.

Where It Fits in an Aurora Design System

The HPC-1 is listed among Aurora Design's optional FMR-3.2 accessories, along with the FMR-DRH1/DRD1 digital radio modules, the FMR-CM2 courtesy module, the FMR-MC1 motor controller and the FMR-HV1 high-voltage relay driver. A typical 6-volt build might combine an FMR-3.2 receiver, the HPC-1 converter and a BTU Smart-3.2 or BTL Smart-3.2 for Bluetooth, all hidden inside the original radio.

Quality

Like all Aurora Design products, the HPC-1 is designed to SAE specifications and built in the USA in an ISO 9001:2000 facility.
