Lenz Booster Transformer

[Shropshire Lad]

Hi all

I'm running a Lenz LZV100 powered by a TR100 Transformer. I'm adding a LV102 Booster to increase the available power.

I have two 15v 5 amp transformers available, is there any advantage/disadvantage with using a transformer for each? Lenz show both running from one transformer in their wiring diagram but that seems counter intuitive to me.

Thanks in advance

I feel sure that the booster won't increase the available power unless you give it a separate transformer.

I have just looked. It shows separate transformers for each unit.

Colin, you must use a separate power supply (transformer) for each Power Station (Booster).

Lenz state this clearly and AFAIA show it in all their wiring diagrams.

 

 

 

 

....I'm adding a LV102 Booster to increase the available power......

I feel sure that the booster won't increase the available power unless you give it a separate transformer.

 

Personally I'd be a little wary of using the term "increase the available power", as it sounds equally as misleading as the term "Booster".

Nothing is "boosted" and there is generally no "increase in power" as such, only more of it (Yes that does sound a little contradictory ! ).

Thanks for the replies guys, I'm going to hook them together to give me all the power to one district I think. Lenz recomend a 10A transformer to supply both when doing this but I'm going to try running them off seperate 5A supplies.

We use a 10a block created from 2x Lenz boosters in certain layout configurations, and both boosters run of their individual 5a power supply and it works fine, but I suspect most folk won't need something as chunky as a 10a block?

[Shropshire Lad]

Thanks for that Martyn, I run G scale which is a bit power hungry!

[Glorious NSE]

Ah that'd probably do it!

[Ron Ron Ron]

Hi Colin, sorry it wasn't clear you are running larger scale.

Have you read the Lenz supplement for combining Power Stations?

If not, it's here.....

 

Parallel LV102 Supplement 2006 (it covers both LZV100 + LV102 and LV102 + LV102).

 

They suggest a larger single switching transformer (an American one is mentioned).

But interestingly then in 7.2 after telling you how to do it they contradict themselves and say they don't reccomend it!

The LV102 instructions linked by Melmerby above show two linked in parrallel with separate transformers, and I can vouch that it works.

 

No wonder Colin was confused.

I was puzzled by that too, but read it again carefully.

 

It is saying that 2 Power stations operating in parallel as a pair (either a LZV + LV or a LV + LV) should use a single transformer.

Any other pairs must use their own separate transformer.

A maximum of 2 Power Stations can be arranged in parallel (i.e. a pair).

 

 

7.2 Common transformer

It is not recommended using a common transformer to power your LZV100/LV102 or LV102 pairs.

 

If it helps, the diagram in chapter 5 on page 8 shows this. Compare it with the diagram in the previous chapter 4 on page 7.
