Lenz Power-1 USP Energy Module


MSRP: $65


POWER-1 is an energy storage module (capacitor) for use with GOLD Series decoders.

USP means “uninterruptable signal processing. ” 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.

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-shrink 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.

All 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:
