> 3.5 | Power Supply

> The power supply of the TC65 Terminal has to be a single voltage source of POWER=8V…30V capable of providing a peak during an active transmission. The uplink burst causes strong ripples (drop) on the power lines.
> The TC65 Terminal is protected from supply voltage reversal and overvoltage. An internal fuse ensures an electrical safety according to EN60950. This fuse is not removable.
> A fast acting fuse I=0.8A with melting integral I²t (0.8 … 1.5 A²s) is necessary to use the TC65 Terminal at a 24V power supply system for vehicles.
> The power supply must be compliant with the EN60950 guidelines.
