GYS FLASH 100.12 HF 100 A 12 V cargador de batería automático de alta frecuencia y fuente de alimentación con pantalla LCD 029415

The GYS FLASH 100.12 HF stands apart from conventional wheeled chargers by using high-frequency conversion to deliver a full 100 A in a remarkably compact, fan-cooled enclosure. It is not merely a charger but a complete workshop energy station: a stabilized 12 V power supply, a diagnostic assistant, and a battery support unit during ECU flashing or showroom demonstrations. With its multi-stage IUoU curve and cable-loss compensation, it charges exactly to the battery’s needs, from 20 Ah motorcycle batteries up to 1200 Ah banks, and maintains up to 1600 Ah. The clear digital LCD keeps every parameter visible, while short-circuit, reverse-polarity, overvoltage, and thermal protections ensure safe unattended operation.

Highlights

• High-frequency technology: 100 A output in a compact, lightweight design
• Stabilized power supply mode for diagnostics, ECU flashing, and showroom use
• Multi-stage IUoU charging curve with automatic voltage adjustment
• Cable compensation for accurate voltage at the battery terminals
• Supports lead-acid (liquid, gel, AGM, MF, Ca/Ca) and lithium LiFePO4 batteries
• Digital LCD display for real-time voltage, current, and mode status
• Forced-air cooling for continuous high-current operation
• IP21 ingress protection for workshop environments

In daily use

Connect the clamps, select the battery type, and the FLASH 100.12 HF takes over. In charge mode it runs the full IUoU profile, bringing the battery to full capacity without overcharging. Switch to diagnostic mode and the stabilized 13.5 V output supports vehicle systems during fault finding. The showroom mode maintains a constant voltage to power demonstration electronics, while battery change mode keeps memory settings alive when the battery is disconnected. The LCD shows the charging current and voltage at a glance, and the fan keeps the unit cool even during long sessions. Its compact size and robust housing make it easy to move between bays or store on a shelf.
