GYSFLASH 102.12 HF Battery Support Unit (5m Cables)
100A Vertical Power Supply. Fanless, Silent & Dust-Proof.
Silent Power for Showrooms & Workshops. The GYSFLASH 102.12 HF is a high-power 100A stabilized power supply specifically designed to be mounted vertically on a wall or car lift. Unlike standard chargers, it features Fanless Technology (no external ventilation), making it completely silent and impervious to dust ingress.
Delivering up to 100 Amps, it keeps 12V batteries at a perfectly stabilized voltage during diagnostic work or showroom demonstrations. This model comes equipped with extended 5-meter cables, offering exceptional reach for overhead or wall-mounted installations.
Why Choose the 102.12 HF?
- ✓ Vertical Design: Space-saving wall or trolley mount.
- ✓ Fanless Tech: 100% Silent & Dust Proof electronics.
- ✓ 100A Output: Sustains modern vehicle diagnostics.
- ✓ 5-Meter Reach: Heavy-duty long cables included.
5 Operating Modes
Diag+ (Diagnostic)
Supplies up to 100A to maintain the battery voltage of diagnostic vehicles. The voltage is fully adjustable from 12V to 14.8V to meet strict manufacturer specifications during ECU flashing.
Showroom Mode
The silent, fanless design makes it perfect for showrooms. It provides current compensation when using electrical accessories (lights, windows, infotainment) without the noise of a cooling fan.
Charging
Advanced charging cycle for all 12V Lead-Acid, AGM, Gel, and EFB batteries. It ensures a 100% charge without supervision, making it safe to leave connected overnight.
Battery Change
Ensures a stabilized power supply during battery replacement to preserve vehicle memory settings (radio codes, seat positions, ECU adaptions).
Power Supply
Transforms the charger into a stabilized, high-power DC source. Adjustable voltage and current limits allow for safe testing of electrical components on the bench.
No Ventilation
The internal electronics are cooled by a massive heat sink rather than fans. This prevents dust, dirt, and metal filings from being sucked into the unit, significantly increasing reliability.
