For the growing demands of smart grid, smart meter applications, WoMaster designs a new outdoor meter box specifically for power meter or DLMS meters. The SCB211DL is a smart DLMS COSEM Meter Cellular Gateway with LTE or NBIoT network. It saves electricity companies great cost and effort to integrating additional DLMS converter or NBIoT router with enhanced cybersecurity features. The IP54 Fire Resistance ABS Enclosure can protect from dust, moisture, and rain from the outdoor environment. The RJ45 connector from Cable Gland connector includes one two-wire RS485 for DLMS Power Meter to read OBIS codes and 12V power input from the Power Meter. No extra power supply is required. The SCB211DL can be customized by different types of DLMS meter and OBIS codes.
To safeguard cybersecurity, security features such as Firewall, OpenVPN, GRE tunnel are supported. The embedded COAP protocol enables HES integration for Smart Meter System. The ThingsMaster OTA safeguards the device from the remote-control center to detect and fix abnormalities at local sites.
