Đặc tính

A professional wireless data transceiver has a frequency band of 150 MHz with air rates of 9600 bps and 19200 bps. The maximum RF output power is 25 watt, which may be configured in five levels from 25 watts to 5 watt. It is appropriate for long-distance data transfers.

1. The industry’s smallest 10W radio in the 150MHz band;
2. Set the transmit power through the setting software, providing 5 levels of selectable power;
3. Use a temperature-compensated frequency reference source to ensure high and stable transmitting and receiving frequencies;
4. The power indicator light, transceiver indicator light and data indicator light make the working status clear at a glance;
5. Precision die-cast aluminum structure combined with professional circuit design has strong anti-interference ability;
6. Using frequency synthesis technology, the frequency can be easily set through the setting software;
7. Provides a variety of data interface configurations to facilitate connection of various external devices for data transmission;
8. Transparent data transmission, supporting point-to-point, point-to-multi-point, and flexible networking;
9. Compatible with voice transmission, making calls easy;
10. Optional handheld intercom accessories allow direct intercom to facilitate construction;
11. Industrial-grade product design with a wide temperature range.

Feeder cable length

If you use the Yagi directional antenna for the receiver, the feeder cable can be chosen from 2 meters to 10 mét. How long do you need for your radio telemetry? The feeder cable is USD2.9 per meter, Feeder connector is USD4.5 per pair.

Bộ chuyển đổi điện

12V 12A for 20-watt power amplifier. 20-watt data transceiver usually works at 5A, but the power supply needs to have room for fluctuations. vì thế, we generally recommend a power supply of more than ten amps. If the power supply used for a long time, there will be aging problems, so the quota should be left a little wider.
