The Sennheiser NT 1-1 CW EU is the genuine switch-mode plug-in mains unit for Sennheiser's ASA 1 active antenna splitter and the L 2015 charging station, sold as a spare or replacement. It accepts any mains supply from 100 to 240 V and delivers a 13.8 V DC output through a 1.6 m cable with a barrel plug, with EU-style mains prongs on the wall unit. It is useful for rental houses, venues and installers who need a spare so a splitter or charger is never out of action, or to replace a lost or damaged original. Standby consumption is very low (at most 0.075 W at 230 V), and it is rated to operate between -10 and +55 degrees C in 5 to 95 percent non-condensing humidity. The unit measures about 164 x 80 x 73 mm, weighs roughly 230 g and carries a 2-year Sennheiser warranty. The splitter and charger themselves are sold separately.
