HO, N, O, TT Scale Command Stations and Expansion

The amplifier LV103 was designed to meet the safety requirements for gauge O, H0, TT and N operation. Track voltage: 11 to 22V. Maximum load capacity up to 5A. Overload results in a temporary safety shut-off of the amplifier.

This unit requires a suitable power supply unit, such as the The TR150. The LV103 supports RailCom operation.

Short and overload protection
Designed to meet NMRA RP-9.1.2
Includes RP-9.3.1 cutout device
Needs either a TR100 or TR150 transformer

Technical specifications:

  • Power supply (Input voltage) with AC voltage: min. 14 volts, max. 19 volts with pure DC voltage: min: 14 volts, max. 24 volts It makes sense to choose an input voltage that is about 2 V higher for DC voltage supply, or approximately the same size or slightly less than the set output voltage (voltage on the track) for AC voltage supply. This avoids unnecessary heat loss in the device, which can lead to premature thermal shutdown. output voltage (Voltage on the track) The voltage on the track is adjustable between 11 V and 22 V in steps of 0.5 V. Depending on the transformer used, this voltage may be lower under load. An output voltage of 16 V is set at the factory. Output current Depending on the transformer used, its voltage and the set track voltage, the continuous current that the amplifier of the LZV200 can deliver differs. Example: With transformer TR150 and setting the track voltage to 16 V, the continuous current is 4.3 A. Overload protection Thermal overload protection.  The overcurrent switch-off takes place after approx. 200 ms with permanent overcurrent (e.g. short circuit). RailCom detector The LV103 is equipped with a global RailCom detector. This detector receives data that are sent by decoders in channel 2 of the RailCom packets. This data is forwarded to the LZV200 control center via the C, D, E lines.

How much power do you need?

The power requirement of a model railroad system depends on the power consumption of all locomotives in motion, the activated locomotive functions, the lighting of the cars as well as functional models such as cranes etc. The power of the LZV100 / LZV200 is not sufficient to supply all consumers safely the track diagram into several supply sections, each of which is supplied by its own amplifier. The size of these supply areas must be dimensioned in such a way that no area requires more current than the connected amplifier can deliver. The additional amplifiers receive the control signals from terminals C and D of the LZV100 / LZV200. Each amplifier needs its own transformer for supply, which must withstand the respective maximum current in continuous operation. The amplifier can be operated with an alternating voltage of up to 19 volts or with a direct voltage of up to 24 volts. Determination of the required amplifiers: Add the sum of the current consumption of all locomotives running at the same time and the illuminated wagons For example: 6 locomotives with a current consumption of 0.7 A each plus 40 light bulbs with a current consumption of 0.05 A each in illuminated wagons result in a total current consumption of 6.2 A. Divide this total current consumption by the maximum current that an amplifier can deliver, and you get the number of power ranges.
