Power supply for router is required b9 V to +36 V DC supply. Protection against
reversed polarity without signaling is built into the router.
The power consumption during receiving is 2.0 W. The peak power consumption during
data sending is 5.5 W. However, values of consumption can be increased, if some expansion
port is equipped. For correct operation it is necessary that the power source is able to supply
a peak current of 1.2 A.
Circuit example:
