DCD-SA2SS1 DCC Concepts Stay-Alive Super High-Power

Zen SUPER high 2-wire power stay alive has exceptional power storage.

In fact, once charged, they have enough power to run an average OO or HO Locomotive more than two metres with the track power removed!

They are available singly (DCD-SA2-SS.1) (was DCD-ZNSSA-1) or in cost-saving packs of three (DCD-SA2-SS.3) (was DCD-ZNSSA-3). Click HERE for a quick video!

Super Stay Alive is the natural partner for your Zen Decoders, however they are also ideal for adding to high quality sound decoders which allow stay alive installation – such as ESU, Zimo and others

Despite their excellent power storage ability, the Super Stay Alive is very good value… and slightly smaller than competitive products.

Installation is easy – Just match the blue and black wires to the blue and black stay-alive wires already attached to your Zen decoder. The overall size of Super Stay-Alives is a compact 32.3mm long x 16.1mm wide x 5.3mm high

(Turn off DC operation using CV29 – if you’re not sure what value to use, click HERE to use a handy calculator from The 2mm Scale Association)

Using Zen with other brand decoders:

Yes, all Zen Stay-Alive products will work with many decoder brands that have stay-alive connections provided along with any DCC Concepts decoder with V9 or above software. Please note however that while any Zen Stay-Alive will also work with many decoders which do not provide stay-alive connections ex-factory, soldering directly to the PCB of a decoder would be required and this needs excellent soldering skills. Please plan and work carefully if you intend to do so.

Unfortunately, because any error will damage the decoder, we do not feel it appropriate that we advise you regarding direct soldering points on any decoder that does not advertise stay alive ability.

(PS: For those who like to know, the blue wire is the positive wire).
