The STACO3A is the latest innovation in keep alive from Zimo, providing 150,000uF of keep alive for your locomotive in a very small package. The STACO3A consists of a charging controller board (10×7.3x2mm) and 2x 2.7V 300,000uF capacitors (4x12mm each). With the capacitors connected in series, they provide 150,000uF at 5.4V, which the board boosts to around 10V for connection to the decoder.
It is recommended to supply the STACO3A with a maximum of 18V, ensure your track voltage is no higher than this. I also recommend insulating all parts of this capacitor setup with kapton tape. Failure to do so may result in the capacitors overheating dangerously, failure of the connected decoder and/or damage to the locomotive body or mechanism.
The components of the STACO3A can be distributed inside your locomotive as desired, making this capacitor setup ideal for very tight installations, particularly N scale.
- 150,000uF 5.4V capacitor
- 10×7.3x2mm – board, 4x12mm – capacitors (each, diameter x height)
- ~2s supply time for a sound equipped N scale locomotive driving with sound and lights on, up to ~3s still turning wheels with sound interruption
Using the supplied diagrams included in the box, simply connect the common positive + wire (blue) and ground wire (grey) from your decoder to the STACO3A board, and the pre-soldered blue and grey wires from the STACO3A board to the capacitors, noting the polarity as described in the diagram. Note, you may have to solder your own ground wire onto your decoder of choice. Feel free to get in contact if you require wiring or installation assistance.
