Our chargers are completely unique to our competitors’.

  • For over 15 years we’ve used a ZVT full bridge topology which guarantees high efficiency (>95%) and low noise levels. Only in very recent times have our competitors begun using this topology in like manner
  • Our control circuits, both for power and charging cycles, are reliable with several redundancies to avoid control losses and components failure
  • We use power modules instead of discrete semiconductors. Although these prove greater in expense, this guarantees higher reliability with vibrations, high currents, thermal heating and protection from dust and acids
