GW-1800-DC09WMLR/4G data concentrator utilizes the latest developments in LoRa technologies to configure and collect data from GATEWAY’s intelligent LoRa lighting controllers and transmits data to and from the GATEWAY cloud-based central server. Data concentrators provide extensive fault monitoring to report on day ON/OFF of circuit breakers, cabinet opening, over/under voltage, abnormal power consumption, low power factors, communication failures, leakage current. All faults are sent to GATEWAY’s cloud-based Central Management System for alarm routing, visualization, and fault correction. Alerts can be sent directly to relevant users via emails or text messages (SMS) or WeChat immediately when they occur. Alerts are time stamped and contains key parameters associated with the fault/alarm.
