DC-DC CONVERTER (i-ELOOP) [i-ELOOP]

id131704503000


Purpose, Function

•  The DC-DC converter (i-ELOOP) supplies the electricity supplied from the capacitor (i-ELOOP) to the vehicle’s electrical devices.
•  If the electricity supplied from the capacitor (i-ELOOP) exceeds the rated voltage of an electrical device, the DC-DC converter (i-ELOOP) lowers the voltage to 12 V and then supplies the electricity to the electrical devices.

Construction

•  The DC-DC converter (i-ELOOP) is installed directly under the front seat (LH).
•  The DC-DC converter (i-ELOOP) has the following inputs/outputs.
