SELC Photocell Controller / Radio Reciever


Vossloh Schwabe Powerswitch Controller


Here you see the SELC Controller and Powerswitch wired inside my Urbis ZX3 Streetlight

How it works

The Photocell switches the street light on at dusk then at Midnight the Radio Reciever picks up the International Time Signal from Rugby this then switches the powerswitch over to the 100w coil on the ballast and dims the street light  in the summer the light switches off at Dawn, in the winter the Radio reicieves the Signal at 05:30am this then switches the powerswitch over to the 150w coil on the ballast and the street light then swiches back to 100% lightout put then the light switches off at Dawn.
