Translated question:
“Hello everyone, I have a TU700-5 Permanent plus 48V, ignition 12V, are these different voltages a problem for the operation of the unit or should they be identical? thanks in advance Best regards”

Hello ​@Luke

I confirm that it is possible for the power supply voltage of the unit (48 Volts) to be different from the voltage received by the inputs (12 Volts).

Once the unit installed, do not hesitate to contact our Support team if you have any doubts about the unit's data at support@trackunit.com

We are happy to assist you.

Wishing you an excellent end of the day!
