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.
