Power supply for router is required between +9 V to +36 V DC supply. Protection against
reversed polarity without signaling is built into the router. Note: The protection against re-
versed polarity is lost if the negative pole is grounded!
The power consumption during receiving is 2.3 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:
The positive pole VCC is marked by a red socket on the power.
Description
Positive pole of DC supply voltage (+9 to +36 V DC)
