The Taramps Smart Charger 70A/90A is an intelligent battery charger and fixed DC power supply engineered for high-performance car audio systems, battery banks, and 12V power applications. Designed with microprocessor control, it automatically manages float and equalization charge cycles to extend battery lifespan while supplying up to 90A of dynamic current during heavy musical transients.

Key Features

  • Dynamic Power Mode (Up to 90A): Delivers a continuous rated output of 70A and up to 90A dynamic peak current (for up to 2 minutes) to power high-demand sound systems without voltage drop.

  • Dual Operation Modes: Functions as an automatic multi-stage battery charger (cycling through 12.6V, 13.8V, and 14.4V) or as a fixed DC power supply selectable at 12.6V, 13.8V, or 14.4V.

  • Automatic Bivolt System: Operates seamlessly on both 127V AC (90–140V) and 220V AC (190–250V) main power grids without requiring manual voltage switching.

  • Integrated Digital Display: Features a real-time voltmeter and ammeter for continuous monitoring of system voltage and current consumption.

  • Smart Cooler & Active Protection: Built-in variable-speed cooling system with integrated electronic protection against thermal overload, battery low/high voltage, and short circuits.
