DC-Transformer 757-28-SD

BUILD TO ORDER

Converter can be used in various applications

Key figures

  • ultrawide input voltage range: 19 ... 70 VDC
  • very high efficiency: up to 95%
  • peak input voltage: 75 VDC
  • output voltage / max. output current: 28.0 VDC / 25.0 ADC

Applications

The DC/DC converter with 28VDC output voltage at 25A rated current is best suited for 24/7 supercapacitor operated AGVs or shuttles.The constant short-circuit current of about 26A and the wide input range of 18 to 70VDC give this galvanically isolated DC/DC up/down converter ideal characteristics in harsh applications. Due to the polyurethane encapsulation and the integrated cable connections, the device has excellent climate-proof properties. Adjustments in the open circuit voltage and thus the charging end voltage are very easy and possible at any time. We are looking forward to your inquiry!
