DC-Transformer 757-48-SD
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: 48.0 VDC / 15.0 ADC
Applications
The DC/DC converter 757-48-SD with 48VDC output voltage at 15A rated current is ideally suited for 24/7 supercapacitor operated AGVs, shuttles or EVs in common. The constant short-circuit current of approx. 16A and the wide input range of 19 to 70VDC makes this galvanically isolated DC/DC step-up and step-down converter ideal for harsh applications. Due to the polyurethane encapsulation and the cable connections integrated in the encapsulation, the unit has extremely climate-resistant properties. Adjustments to the open-circuit voltage and thus the final battery charging voltage are relatively easy to implement and can be made at any time. We are looking forward to your enquiry!
