Power supply
- Nominal voltage range: 18V..45V DC, 20V..30V AC
- Maximum continuous (average, depends on supply voltage) supply current: +800 mA max
- Peak (momentary) supply current: 2 A
RF specification
Antenna
The antenna must meet the requirements as in the table below:
| Antenna frequency range | GSM/LPWA supported frequencies as described in RBVND-Lite_General |
| 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 RBVND-Lite modem.
| Parameter | Condition | Min | Max | Unit |
|---|---|---|---|---|
| Ambient operating temperature | 0 | 60 | °C | |
| Storage temperature | -40 | 85 | °C | |
| ESD | At antenna connector Contact |
± 6 ± 15 |
KV | |
| Humidity | % |
Warning! Exceeding the above values may cause permanent damage to the modem.
