Model: ACTii AC6916

EAN: 6931240069165 SKU: 691649116

• All basic components are originally imported, our transceiver modems have a lot of advanced features with smaller size and lower cost.
• The maximum TX power is 100mW, all technical parameters meet European industrial standards
• Temperature compensators are designed to improve frequency stability than: SPPM
• Aluminum alloy housing, compact size, great heat dissipation, good shielding, excellent electromagnetic compatibility and strong anti-interference
• The functions of reverse power and overload protection and antenna surge protection greatly improve the reliability
• The parameters can be configured by programming, such as TX power, frequency point, data rate, address and so on.
• Very low power consumption, standby current is only 28mA (even less in energy saving and sleep modes), TX current 0.2A
• Built-in watch-dog and precise time circuit, the modem will automatically restart in case of an abnormal situation and will work with the previous parameters.
• The transceivers have the original SEMTECH SX1278 chip, customers appreciate this chip very much for its reliability

Description

Wireless data transceiver with standard RS232 RS485 interfaces. They are a half-duplex TX and RX modem with LoRa technology and transparent transmission mode. Supply voltage range from 8 V to 28 V, operating frequency: 425-450.5MHz (default: 433 MHz)

LoRa spread spectrum technology with direct sequence provides greater communication distance and better concentration of power density, as well as excellent anti-interference ability. The FEC algorithm provides higher coding efficiency and correction ability. Disrupted data packets will be proactively corrected in case of sudden disruptions, which greatly improves the reliability and distance of communication. Without FEC, the disrupted data packet will be discarded. Transceivers have data encryption and compression. Data sent by air is randomized, a rigorous algorithm makes data capture more reliable. The data compression function has the ability to shorten the data transmission time, which in turn reduces the possibility of interference, and thus improves the reliability and efficiency of communication.
