3.4.3 Power Supply
The INSYS GPRS Ethernet requires a power supply of 10 to 60 V (DC) at a maximum of 5%
ripple.

Caution - No overvoltage protection!
The INSYS GPRS Ethernet does not have a fuse.
Surges and excessive voltages may result in the destruction of the de-
vice.

The following table shows the values that were determined for a signal field strength of
26 and an ambient temperature of
77°F (25°C). The current consumption and therefore
the power consumption may increase during poor network conditions. The threshold
value tolerances are subject to the typical fluctuations. A maximum of one value may be
operated in the threshold value range.
value tolerances are subject to the typical fluctuations. A maximum of one value may be
operated in the threshold value range.
These are average values for estimating the current consumption. The current consump-
tion during data transmissions may also increase if the antenna is not adjusted correctly.
This can occur for the following cases:

This can occur for the following cases:
The antenna and/or the antenna cable are not adjusted to 50 Ω impedance.
