Design and Construction

The RFX-90 is housed in a compact aluminum enclosure measuring 214 × 208 × 50mm and weighing 2.9kg. The design incorporates dedicated input and output terminals for positive and negative power connections, allowing the capacitor to be integrated directly into the vehicle’s power distribution path.

An integrated digital voltage display provides real-time monitoring of system voltage, while the REM terminal allows synchronized operation with the vehicle’s audio system.

The unit also incorporates four 25A protection fuses to support safe operation within the audio system.

Power Support Function

The RFX-90 is designed to function as an energy storage device within the vehicle audio system.

Installed between the vehicle battery and amplifier, the capacitor stores electrical energy and makes it available when the audio system requires additional current. This operating principle helps support the power supply during periods of increased demand from connected amplifiers.

According to the connection diagram, the RFX-90 receives power directly from the vehicle battery and distributes power to one or more amplifiers while remaining integrated with the system’s remote turn-on circuit.

System Integration

The RFX-90 is designed for use with aftermarket car audio systems utilizing external amplifiers.

Its dedicated power input and output terminals simplify installation within the vehicle’s electrical system, while the REM control connection allows the unit to operate together with the source unit and amplifier system.

The compact dimensions also allow installation in a variety of vehicle configurations where space efficiency is important.

Product Positioning

Within the Rebec ecosystem, the RFX-90 serves as a dedicated power management accessory designed to support amplifier-based audio systems.

Rather than functioning as an audio processor or amplifier, the RFX-90 focuses on electrical energy storage and power delivery support, making it a complementary component for systems that utilize external amplification.

Its large capacitance, integrated voltage monitoring, and dedicated installation architecture make it a practical addition to advanced car audio systems.
