High frequency charging devices

Economy due to high reliability

Sustainability through maximum energy efficiency

Legal certainty through professional project engineering

Occupational safety through expert testing concepts

There are many high frequency charging devices. But we harmonize economic efficiency, sustainability, legal certainty and occupational safety. This is because our HF charging devices are the only ones with a modular design that can be individually parameterized. And with a high energy efficiency due to an efficiency of up to 96%, the investment in an Allgäu battery HF charging device is covered by the saved electricity costs after approx. 2 years.

Maximum energy efficiency

High reliability

Future viability through CAN bus communication

Extended battery service life

The high-end ALLtrac® Plus charging device leaves nothing to be desired. Sustainable energy efficiency through modern high-frequency technology is just as much a must as optimum operational reliability and high serviceability. Freestyle: ALLtrac® Plus offers a wide range of benefits that make it unique. Technical features such as high-current charging, automatic battery recognition, integrations via CAN bus or intelligent networking for Industry 4.0 make your everyday work in intralogistics easier. And quite incidentally: Future viability is already assured through compatibility with lithium-ion batteries!
