DALI Individual Metering Switch


The MES controller is designed to monitor and transmit telemetry from HID Street Light fixture based on magnetic ballast and PF capacitor, 70W-1,000W or LED luminaires.

It is communicating using ENELTEC’s proprietary commands over standard DALI protocol.

The switching process is synchronized with the line voltage.

The load switching (ON/OFF) is done at zero current.

The MES controller is designed for installation as additional device in the base of the pole between the mains line and the luminaire.

The MES unit is designed to be controlled by remote control system using DALI communication according to DALI standard IEC62386.
