Item # 257.001
Key figures
- ultrawide input voltage range:15 ... 35 VDC
- very high efficiency:up to 97%
- peak input voltage:37 VDC
- output voltage / max. output current:28.0 VDC / 13.0 ADC
Applications
Short-circuit proof buck-boost charging converter for primary use in supercapacitor-powered autonomous systems with an output-side backup battery. The converter with 28V output and up to 13A short-circuit current is designed to power to 13.8V batteries in parallel. The alternative 258E-28-SD with an extended input voltage range of 16 ... 55V for 48V supercapacitor powered systems complements the input voltage range generously.
