ERCO Minirail track made of aluminium for 48 V operation The Minirail track is very flexible in terms of possible control types; switching, dimmable, DALI, ZigBee or Casambi are possible depending on the configuration. The aluminium profile is also particularly space-saving thanks to its slim design and requires only two conductors. Supplemented with the appropriate accessories, Minirail can be used to implement a compact, versatile and high-quality lighting solution - two insulated copper conductors (4.15 mm² each), one circuit - max. 500 W (48 V / 10 A)
