Cobalt Accessory Decoders Cobalt iP DCC Decoder Stall Motor Drive Type (1 Output/High Power) AD-HP is a Single output high power DCC accessory decoder for Cobalt type motors. On DC or DCC, AD-HP is easily capable of powering several Cobalt Classic... and also works well with "other brand" higher current devices. (Interfaced properly, it even makes Lemaco and Fulgurex point motors a little less angry sounding.) The AD-HP has zero current draw when not changing so many of them can connect straight to track power and not load the bus. The ability to change several points at once and also operate with DCC or push-button switches as required keeps wiring really simple for complex crossovers and large fiddle yards too. Really simple set up and addressing. Designed to fit neatly into the side of Cobalt Classic Analog or iP Analog and give you the option of digital or push-button control. AD-HP Also works really well on DC power to make DC control and wiring the simplest it has ever been.
