The much anticipated Lenz POWER-1 energy storage module for use with their GOLD Series decoders is finally becoming available. 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. CV112 is used to set the delay for the motor to be switched off. The default setting is approx. 0.25 sec.
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 sleeve that protects sensitive components and facilitates installation. 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. Trust that it will take a steady hand and nerves of steel but it can be done. For the faint of heart the work can be done by the same jobbers that do decoder installations.
