7500-20000J/ 高压充电电源

These chargers constitute the high end range. Double Resonance Technology operating at high frequencies （50 kHz） offers a smooth switching to all the critical components and provides them a non-stressing behaviour.

Internal power dissipation, harmonics & ripple are significantly reduced.

Hence, they can operate without damage or interruption in rugged environments Many of them are used at full power 24 h/day, 7 days/week with no failure for many years. Four ranges of charge rates are offered in this series from 7.5 kJ/s to 20 kJ/s.

For higher charge rates, they can be configured to run in master/slave mode to reach 50 kJ/s and more.

An oil tank is integrated for the models from 20 kV and more.
