DC-Transformer 142E-13.8-SD

MINIMUM ORDER QUANTITY

Converter can be used in various applications

Key figures

  • ultrawide input voltage range: 16 ... 70 VDC
  • very high efficiency: up to 96%
  • peak input voltage: 75 VDC
  • output voltage / max. output current: 13.8 VDC / 15.0 ADC

Applications

DC/DC step-down converter for 24VDC, 48VDC and 57VDC systems with CC-CV charging characteristics. This Demke converter is optimised for 48V low-voltage networks and can be supplied by 57V Li-Ion battery systems with sufficient reserves. The still very high output current or short-circuit current of 15A is designed for 12V consumer and 13.8V battery charging applications. The flat and compact design with a specific power of 1.25Watt/gram is ideal for space-critical applications. News article available.
