DC-Transformer 145E-27.5-ON

Converter can be used in various applications

Key figures

  • ultrawide input voltage range: 30 ... 100 VDC
  • very high efficiency: up to 97%
  • peak input voltage: 120 VDC
  • output voltage / max. output current: 27.5 VDC / 4.4 ADC


Battery charger with constant short-circuit current and integrated polarity protection diode to avoid battery back discharge. Output optimized for 27V batteries with e.g. two 13.8V battery modules connected in series. The battery charging current can be changed without any hardware difficulties. The 145 series can be customized universally in the output current and in the output voltage. Just configure your supercapacitor module yourself!
