Industrial Protection
Adopts industrial design, 7*24 hours high load all weather reliable work, to meet the outdoor poor working environment needs.
supports Level 4 ESD (Static), level 3 Surge (Surge),level 3 EFT(Electrical Fast Transients),internal process watchdog and external hardware watchdog, to ensure normal operation of the equipment and immunity from the outside environment interference.
Data Penetration
Lianbo series products, no matter serial to ethernet connector or Cellular Modems, are transparently transmitted networking devices.
Transparent transmission means that the original data of the serial port can be converted into TCP/IP packets for transmission without changing the original data communication content. As a result, the DTU can be connected to various user devices using serial communication without modifying the user devices.
Quality Assurance
For 10 years of advance, we have always been remaining true to the concept of reliability and stability in building our quality strength. Our products have passed the certification of the ISO9001 quality management system. With nearly 100 patents and software copyrights, we have won many certificates from authoritative bodies, such as the Ministry of Industry and Information Technology, CCC, CE, FCC, RoHS.
Solutions & Applications
Intelligent Remote Distribution Box Monitoring Solution The distribution box is embedded with the DTU distribution device, distribution device power module, and distribution device power supply. By leveraging the intelligent remote monitoring function, you can remotely collect the electric meter readings and implement networked transmission. In addition, with the help of electricity monitoring platform of USR Cloud, you can manage and control the electricity safety and electric energy over the cloud.
