Yes, the low price is great, but you don’t seem to have absorbed what I said about short circuit protection… it can be a very sophisticated function to sense accurately a real short and temporary overcurrent, etc.
After all my experience, I have never seen a system that was as “smart” as the Zimo, and it is a NECESSITY when you get up in the 10 amp range and over…
Using this product, I would need to add more circuit breakers to protect locomotives, switches, etc. AND it would have to be set lower than 20 amps depending on the circuit breakers used.
So, the benefit is one large 25 amp system, broken into smaller power districts, definitely do-able, but I would wait to see what protection I could enable with 10 amp power districts.
So, I agree, this could be cost effective.
You have made a somewhat misleading comparision though, not comparing apples to apples… this is a booster only, not a complete top end wireless system (and you have the Zimo price at full list, no one buys at full list)… why not compare this inexpensive system with limited capability to some other inexpensive system with limited capability, like MERGE?
So, yes it could be part of a low cost high amperage system, but at that current level, the system MUST include more intelligent circuit breakers.
By the way, I have an inexpensive portable DCC system, the basis is a PowerCab and a Tam Valley 5 amp booster (which you could add more in parallel for even less cost and safer operation). You can’t beat that price, and you can have 20 amps with four 5 amp districts for the same $$. (or one 5 amp system for $150 less)
The next module applied is a $75 laptop with an inexpensive wireless bridge, now I have a full JMRI system, with color touchscreen display and support cell phone throttles.
The last thing I am adding is a RailDriver for someone that wants to sit and operate all the controls of a real loco WITH lots of function buttons for DCC.
