Not surprising. The controller that fried looks to be a brake type controller they are on or off nothing in between. They are used when the vehicle is already stopped, if you want them to last anyhow.Of course they may have up-dated their Controls, I haven't looked
Are you sure about that? If so where would that high of a voltage come from in a truck that would be either 12V or 24V? After all that is where this came from.And with the single series connection there would be six coils requiring 12 volts each at maximum power, and so for full breaking torque at 100% duty cycle 72 volts would be required.
The intended application for this specific piece of hardware is in a stationary chassis dynomometer application. In addition, the setup manual describes in great detail the arrangement for having three pairs of coils operating on 24volts. with the maximum current draw being in the 43.5 amp area.Are you sure about that?

Following most of what is said here I predict smoke
Just to bad that following your advice in this can't be followed by a law suit! Truck or not the original retarder was powered by a single 12 or 24 volt system, and all coils were used at one time, powered by that system.The intended application for this specific piece of hardware is in a stationary chassis dynomometer application. In addition, the setup manual describes in great detail the arrangement for having three pairs of coils operating on 24volts. with the maximum current draw being in the 43.5 amp area.
Given that this particular setup will be stationary and mains powered, an alternate arrangement with each of the 24 volt pairs in series for a maximum requirement of 72 volts, is a better choice for operation, as only one third of the current will be required.
There will be no trucks involved in this installation for this application.
You mean like the guy that can't understand this retarder was orininally from a truck?There can be no understanding by those unable to see the difference between a parallel circuit and a series circuit.
If you take the time to look at the PDF the TS gave the only difference between the 12V and 24V models is the way the coils are wired, 12V is parlell and 24V is series. But thats said, each pole/coil pair is SWITCHED on separately, you choose the number of coils needed 1-3 to apply the needed drag. Running those coils from 80V is not a good idea.There can be no understanding by those unable to see the difference between a parallel circuit and a series circuit.
