Power-1 Module 1
usp - "uninterruptable
signal processing
Ensures continuous data transfer
to the decoder even if electrical
contact to the track is interrupted.
POWER-1 usp Module
Art. No. 10490
August 2005
POWER-1 is an energy storage module for use with GOLD
Series decoders. This storage unit supplies the decoder and
the locomotive with power when there is an interruption of
electrical connection to the track (e.g. dirty tracks).
The USP circuit of the GOLD decoders allows the decoder
to receive the DCC signal without a direct electrical
connection to the track. During the period where track
electrical power is not present the USP circuit switches to
the backup power provided from the POWER-1 storage
module to ensure continued control of the motor. If digital
information is no longer transmitted, the motor will be
deactivated. This prevents the locomotive wheels from
continuing to turn, for example: in the case of a derailment.
POWER-1 is like an "electronic flywheel", but thanks to the
USP technology the stored energy is used only when
necessary.

Connecting and installing the POWER-1
storage module to the GOLD decoder
The POWER-1 storage module measures approximately
0.9" x 0.55" x 0.39" (22 x 13.3 x 9.4 mm) which allows easy
installation in most HO and larger locomotives and many N
scale tenders.
Three wires provide the connections between the POWER-1
storage module and GOLD decoder. The module is
encapsulated by a heat-shrinking sleeve that protects
sensitive components and facilitates installation. It also
serves to prevent short-circuits to the metal components
inside the locomotive - do not remove it from the module on
any account.
GOLD decoders are equipped with soldering pads to which
the cables of the POWER-1 storage module must be
soldered. The precise location of these surfaces is
described in the respective decoder manual:

When connecting the POWER-1 storage module to a GOLD
decoder, please proceed as follows:
•Solder the blue cable to soldering surface "U+".
•Solder the pink cable to soldering surface "charge".
•Solder the brown cable to soldering surface "GND".
While soldering take care not to create short-circuits
between the soldering surfaces and other components of
the locomotive decoder as this could severely damage the
decoder! Also be sure to not locate the POWER-1 module
next to a hot surface.
Note!! Soldering should only be performed using a
tool specifically designed for soldering sensitive
electrical components.

Power-1 Module 3
When no digital signal is present the Gold Decoder will shut
down the motor to prevent accidental movement of the
locomotive. Gold decoders allow you to configure the time if
no digital signal is detected after which the motor is switched
off. CV112 is used to set this value. The default setting is
approx. 0.25 sec which is fine for most installations,
Storage time of the POWER-1 storage
module
A natural question is:
"How far will my locomotive run if
there is a power interruption?"
There is no straight answer to this, because the length of the
distance covered is subject to two factors: the power
consumption of the motor and the gear of the locomotive.
The higher the power consumption of the
motor, the faster the storage module will
become empty. Thus, the distance covered will
be shorter than it would be if a motor with lower
power consumption was used instead.

Poor electrical contact or dirty track is normally a very short
intermittent event. However the result of this brief loss of
electrical contact can reduce the typical packet reception of
a decoder in a model locomotive to less then 60%. The use
of a POWER-1 module results in a nearly 100% packet
reception resulting in a significant improvement of actual
operating performance of the locomotive.

Lenz GmbH does everything it can do to ensure that its products are free from
defects and will operate for the life of your model railroad equipment. From time to
time even the best engineered products fail either due to a faulty part or from
accidental mistakes in installation. To protect your investment in Digital plus
products, Lenz GmbH offers a very aggressive 10 year Limited Warranty.
This warranty is not valid if the user has altered, intentionally misused the Digital
Plus product, or removed the product's protection, for example the heat shrink from
decoders and other devices. In this case a service charge will be applied for all
repairs or replacements. Should the user desire to alter a Digital Plus Product, they
should contact Lenz GmbH for prior authorization.

any item that that has failed due to manufacturer defects or failures caused by
accidental user installation problems. Should the item no longer be produced and
the item is not repairable, a similar item will be substituted at the manufacturer’s
discretion. The user must pay for shipping to an authorized Lenz GmbH warranty
center.
Year 2 and 3: A full replacement for any item will be provided that has failed due
to manufacturer defects. If the failure was caused by accidental user installation or
use, a minimal service charge may be imposed. Should the item no longer be
produced and the item is not repairable, a similar item will be substituted at the
manufacturer’s discretion. The user must pay shipping to and from the authorized
Lenz GmbH warranty center during this portion of the warranty period.
Year 4-10: A minimal service charge will be placed on each item that has failed
due to manufacturer defects and/or accidental user installation problems. Should
the item no longer be produced and the item is not repairable, a similar item will be
substituted at the manufacturer’s discretion. The user must pay shipping to and
from the authorized Lenz GmbH warranty center during this portion of the warranty
period.
Please contact your dealer or authorized Lenz GmbH warranty center for specific
