NOTE: External energy storage with MS590N18
Due to the extreme miniaturization
, the “Next decoder” MS590N18 does NOT contain previsions
to connect an external energy storage directly.
It is possible to connect ELCOs (practically without limitation) to “GEM. Pluspol” (common posi-
tive) and ground, although, WITH additional components and a dielectric strength suitable for the
running voltage (usually 25 V):
The resistor prevents an inrush current too high, the diodes enable Service mode programming,
software updates and sound loading by dropping the voltage despite higher capacities.

Controller
STACO1/STACO3 STACO2
2 mini Goldcaps, STACO3 and Next-Decoder (example MS590N18) in series
The StayAlive controller is connected via wires to the solder pads
“
common positive
” and "
GROUND " of the decoder (two-pole!).
STACO3A: 2 mini Goldcaps à 0.3 F /2.7 V, 4 x 12 mm, 150,
000 µF;
STACO3B: 2 mini Goldcaps à 1 F /2.7 V, 6.4 x 9.8 mm, 500,
000 µF
The STACO1 comes with 3 mini Goldcaps à 0.3 F/2.7 V, 4 x 12 mm as the
actual energy storage, which, connected in series, represent a capacity of
100,000
µF.
Of course, all 3 should preferably be connected, but it also works with 2 (with
about 50
% runtime) if there is a lack of space.
The wire connections between the
controller board and the mini Gold-
caps make their positional separation
possible, and thus in many cases the
accommodation of the StayAlive tech-
nology.
The STACO boards contain a step-up
voltage converter that sucks the Gold-
caps from their full charge state (8
V
for 3 pcs; 5.2
V for 2) to their almost
full discharge (2
V) and delivers a
constant 10 V voltage. This is enough
for driving and for uninterrupted sup-
ply of the sound amplifier (runs on
5
V) without volume loss.

Next18-connection
A Next18 decoder can be
plugged on like on an adapter
board, the STACO2 then outputs
the decoder connections via 13
soldered strands.
The STACO2A set contains
13 soldered wires and
