Hi,

 

As I was browsing the internet, looking at controllers, I noticed that controllers with variable brake capabilities have different OHM brakes.

 

I've seen them advertised with low OHM rating up to 25 OHM for the brakes.

 

How does "OHM rating" affect braking please?

 

The higher the better/finer adjustability?

 

Thank you.

The higher the brake resistor ohm rating, the more brakes can be dialed out. Theoretically.

as more powerful motors have lower resistance, the low end cars use higher Ohm brake pots and vise versa. e.g., 1/32 25Ohm, comm'l. track 24ths 2Ohm.

Thank you Jeff, Steve for that info!
