This technology is mostly
relevant to industrial specifications.
This is the most tried and tested
technology still in use today. Its reputation is based on its good performance in extreme
conditions and its excellent track record over 20 years.
The most requested voltages are
currently 24 DC, 48 VDC, 110DC, 127VDC and 220VDC. Capacity is almost unlimited.
Chargers of this type are often
associated with industrial inverters or NiCd batteries.
Their main advantage is that they
are easily adapted to meet specific needs. Their principal limitations are their size that
requires specific installation rooms, and, an only average electrical output.
