Electrical specification
Power supply
- Nominal voltage range: 5..30 V, 10%.
- Maximum continous (average) supply range: 2.5 W.
- Maximum continous (average) supply current: 200 mA at 12V, 100 mA at 24V.
RF specification
Antenna
The antenna must meet the requirements as in the table below:
| Antenna frequency range | Supporting GSM, UMTS or LTE frequencies |
| Impedance | 50 Ω |
| DC impedance | 0 Ω |
| Gain | 0 dBi w/o cable; 2dBi w/ cable |
| VSWR (with cable) | -10 dB |
The antenna chosen for working with the modem should best fit to the circumstances of the environment it is used in. When the modem is placed in a room, or somewhere where the range of networks signal is too low, an outdoor or a specific indoor antenna should be used.
Environmental characteristic
Table below gives the environmental operating conditions of RB900SG modem.
| Parameter | Condition | Min | Max | Unit |
|---|---|---|---|---|
| Ambient operating temperature | -20 | 60 | °C | |
| Storage temperature | -20* | 45* | °C | |
| ESD | At antenna connector Contact |
± 6 ± 15 |
KV | |
| Humidity | 5 | 85 | % |
* - For long period of storage the recommended temperature range is from 15℃ to 35℃
Warning! Exceeding the above values may cause permanent damage to the modem.
