PF3 technology: beyond the traditional transformer

At the heart of the PF3 series is a conversion system based on frequency multiplication. This design provides technical advantages usually reserved for high-frequency (HF) chargers, which are often more expensive and complex:

  • High energy efficiency.
    Reduces thermal losses, aligning energy consumption with that of common HF forklift chargers.
  • Grid quality.
    Thanks to the integrated Power Factor Correction (PFC) system, the PF3 lead-acid charger features an average power factor exceeding 0.99. This ensures maximum plant efficiency and avoids reactive energy penalties on utility bills.
  • Charging stability.
    The output current is stable and leveled, eliminating spikes that stress the internal battery plates.

Charging for lead-acid traction batteries and intralogistics

The PF3 forklift charger is designed to handle multi-shift workloads without performance drops, making it the ideal partner for modern warehouse fleets powered by lead-acid traction batteries.

Advanced charging strategies

  • Conventional charging.
    Precise algorithms for traction batteries with automatic equalization and maintenance phases.
  • Opportunity charging.
    Supports short “top-up” sessions during breaks, increasing forklift autonomy.
  • Electrolyte management.
    Pulsed mixing system that counteracts acid stratification, extending battery life by up to 20% compared to traditional chargers.

Automatic cable voltage drop compensation ensures the battery always receives the correct energy. The advanced charging algorithm maintains stable conditions and preserves battery performance over time.

Supported lead-acid battery types

The PF3 charger is designed for charging the main types of vented lead-acid batteries for electric traction, compliant with European (DIN) and international standards:

  • PzS tubular plate batteries (DIN standard).
    Including low-maintenance PzS-ET variants and versions ready for electrolyte circulation.
  • PzB tubular plate batteries (British standard).
  • Flat plate batteries.

This compatibility makes the PF3 suitable for most applications in the logistics and intralogistics sectors.

Eco-friendly design, repairability, circularity

Unlike mass-market commercial products, the PF3 series is designed by integrating circular economy principles:

  • Steel enclosure.
    Ultra-robust mechanical structure, resistant to impacts and vibrations typical of charging areas.
    No plastic structural or aesthetic components    .
  • Guaranteed repairability.
    The discrete component design allows for quick and simple maintenance, reaching maximum longevity. GEBAT guarantees spare parts availability for at least 20 years.
  • Eco-design.
    Engineered for easy disassembly and end-of-life recycling, in full compliance with WEEE and RoHS directives.

Industrial charger monitoring

Fleet management is simplified by an intuitive digital interface:

  • LCD display.
    Real-time visualization of voltage, current, charged Ah, charging time, and any charger anomalies.
  • Cycle history.
    The internal datalogger stores parameters of the latest charging cycles for preventive diagnostics.
  • Energy counter.
    Immediate verification of consumption for precise operational cost control.
  • Fleet management integration.
    Option to add USB or WiFi ports for data collection and remote control.

Charging room installation

PF3 chargers offer easy integration into industrial charging areas:

  • Wide range.
    Available in various cabinet types and configurations, including IP54 versions.
  • Flexible installation.
    in centralized stations or distributed layouts. 
  • Operational simplicity.
    Installation, software reconfiguration, and AC/DC cable replacement are immediate and require no special equipment.

Reliability and protection

The PF3 is designed for continuous operation in demanding industrial environments. The power conversion system prioritizes robustness and long operational life.

The electronic protection system constantly monitors critical parameters (over-temperature, overload, anti-arcing) and prevents abnormal operating conditions, ensuring minimal downtime.

In case of an anomaly, the automatic diagnostic function provides useful information for effective troubleshooting.
This design philosophy makes the PF3 particularly suitable for plants where industrial lead-acid chargers must operate daily with zero interruptions.
