Description
The power section is built on a mains-frequency transformer and a rectifier, without high-frequency conversion. Such a design is not very sensitive to mains fluctuations and is easy to repair on site, although the unit is heavier and larger than the HF counterpart. As options, the trak | air electrolyte mixing compressor, which equalises the acid density in the cells during charging, and extended cables for charging places remote from the machine are installed. Electromagnetic compatibility is confirmed to EN 55011, EN 61000-3-2 and EN 61000-3-3, i.e. the unit limits harmonics and flicker in the plant's mains.
How to choose
The model is selected by battery voltage and capacity; the range of 24–80 V DC and 45–1800 Ah covers most warehouse forklifts. If the battery is flooded and works in multi-shift mode, the trak | air option should be ordered. When efficiency, lower weight and fast charging matter more, look at the high-frequency trak | charger HF range, where HF giant charges to 95% in 2.5 h and the single-phase HF classic has an efficiency of over 85%.

FAQ
Which batteries is trak | charger LF classic suitable for?
For traction batteries of 24–80 V DC and 45–1800 Ah used in forklifts and other warehouse equipment.
Can an electrolyte mixing system be connected to LF classic?
Yes, trak | air is among the options together with extended cables. Mixing is appropriate for flooded batteries in intensive use.
How does a transformer charger differ from a high-frequency one?
LF classic works at the 50 Hz mains frequency, is simpler and more durable, but larger in size. The high-frequency trak | charger HF units are more compact, and HF classic has an efficiency of over 85%.
Which EMC standards does trak | charger LF classic conform to?
EN 55011, EN 61000-3-2 and EN 61000-3-3, so the unit is connected to the plant's general mains without additional filters.
