DC-Transformer 757-27-SDB4

Converter can be used in various applications

Key figures

  • ultrawide input voltage range: 24 ... 70 VDC
  • very high efficiency: up to 95%
  • peak input voltage: 75 VDC
  • output voltage / max. output current: 27.0 VDC / 22.0 ADC

Applications

The DC/DC converter with 27VDC or 29VDC output voltage at 25A rated current is ideally suited for 24/7 supercapacitor operated AGVs or shuttles.The constant short-circuit current of approx. 26A and the wide input range of 18 to 58VDC give this galvanically isolated DC/DC step-up and step-down converter ideal properties in harsh applications. Due to the polyurethane potting and the integrated cable connections, the unit has excellent climate-proof properties.Adjustments to the open-circuit voltage and thus the final charging voltage are very simple and possible at any time. We are looking forward to your enquiry!
