DC-Transformer 344DH-13.8
Key figures
- ultrawide input voltage range: 22 ... 160 VDC
- very high efficiency: up to 92%
- peak input voltage: 170 VDC
- output voltage / max. output current: 13.8 VDC / 5.0 ADC
Applications
Galvanically isolated DC-DC buck converter with ultra wide input voltage range for use as a battery charging converter. The DC/DC converter is designed for use in Supercapacitor powered systems with 12V backup battery. Due to the isolation, the converter is used where the negative output voltage must be connected to the chassis.The 13.8V output voltage can easily be modified to a 12V output voltage. Fields of application: DC/DC converter 12V, DC/DC converter 13.8V and DC/DC converter 19V for IT-systems.
