Hello Tim Wilhelm and ET list,
Just a quick note to set the record
straight.
The Alltrax controller does not have to be
"programmed" by the end user. It's "Programmable" such that the end user
can change the current limits and the throttle response times, battery upper and
lower limits, but this is accomplished by moving a slider such as the ones you
find on your volume control in your audio programs. No programming is
required.
The 50% duty cycle rating RJ Kanary talked about is
the lightest load you can put on a controller. At 50% the main switching
transistors are on for half the time and the freewheel components, diodes or
transistors, are on the other 50%. Anything above or below that point and
your current capability drops because the main switch or the freewheel circuit
will be conducting harder which makes the heat generated concentrate in
those devices.
Our controllers are rated over time and at
full throttle and that's how we test them.
Thank you for bringing this to our attention guys
!
