DC-Transformer 757-24-SD
Key figures
- ultrawide input voltage range: 18 ... 70 VDC
- very high efficiency: up to 95%
- peak input voltage: 75 VDC
- output voltage / max. output current: 24.0 VDC / 25.0 ADC
Applications
Galvanically isolated DC-DC converter with 24V output for the electric vehicle sector, optimized for the 48V input of Li-Ion batteries. Supercapacitor-powered mobile applications are another possible area of application. The DC-DC converter discharges the supercaps up to 12V. The high input currents up to 40A and the very low internal resistance of the supercapacitors do not cause this device any trouble!
