YWACDhttps://www.cca.co.uk/image.php?filename=ywacd.jpg&stockcode=YWACD&category=0007003c000a&width=1000&height=1000The YWACD is an 8 way lamp test module designed for use with modern LED based indicator lamps. Filament lamp test modules utilise diodes and only allow a half cycle to pass which invariably is not sufficient to strike a LED. The new YWACD is constructed in a manner that allows the full potential to pass, gives full isolation per lamp circuit and at the same time gives full back feed protection. The YWACD is designed to save on wiring time where "lamp test" is called for in specifications and cable congestion on crowded doors.
