Dispositivo LB40 e3tcity

E3TLight devices integrates remote control, on/off switching of streetlight network, dimming and scheduled programming, monitoring electrical parameters and WiFi communication, in a single unit.

Esquema de instalación LB40 e3tcity

Box control is the best choice for installations where lighting must be controlled by groups, where all luminaires behave the same way.
LB40 controller enables MODBUS communication with three-phase network analyzers and lighting board flow regulators. It also enables communication with any individual streetlight through WiFi.
