Technical Data INSYS GPRS 5.0 serial

104

12.3 Power Supply

All specified technical data was measured with a nominal input voltage, full load,

and an ambient temperature of 25.0 °C. The threshold value tolerances are sub-

ject to typical fluctuations. A maximum of one value may be operated in the

threshold value range.

The values were determined for a GSM receiving field strength of 16. For lower

field strengths on site, the values will increase, especially for CSD or GPRS data

transmissions.

The current consumption during data transmissions may also increase if the an-

tenna is not adjusted correctly.

This can occur when:

 The antenna and/or the antenna cable are not adjusted to 50 Ω impedance.

 The antenna that is being used is misaligned due to the situation at the instal-

lation site (metal parts …).

To operate the INSYS GPRS 5.0 serial, a suitable device protection must be used.

Power supply: 10.0.60 V DC

Current consumption - during normal operation -:

Supply Voltage 10V 24V 36V

Field strength 26 26 26

Standby 140 mA

60 mA 42 mA

CSD Data transmission 195 mA

84 mA 60 mA

GPRS Data transmission 290 mA

84 mA 60 mA

Note: Average values during data transmission and switched-on relay

(AT**OUT1=close, AT**OUT2=close).
