Specifications of TC65 TERMINAL

• Rohs Compliant: YES

3.5
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 1.25A with melting integral I²t (0.9 … 1.3 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.
