Hi,

 

I have hand-assembled this one-off PCBA.  Please see my response to the same question in the article.

 

Thanks!

Hi, do you know whether the Ford / Mercedes Part would work correctly if the input signal would be 20 kHz too?
Thanks

Hi,

 

The module needs a 100 Hz input, +/- something.  I did fiddle around with the input frequency but don't recall when it drops out.  In any case, if you do have an ECU to drive it, those often have trouble getting to 20 kHz on the PWM output.

Sorry me again with a perhaps dumb question. Can I use them as a Solid State relay with added slow up / down functionality with a PW of 100% (read no pulse at all).

Here In germany the A-Klasse Parts are like 4-5€ used so why bother with a relay?

Thanks

Uli

Hi,

 

If you look at the table I included, the module shuts off above 90%. I think that's a safety feature, in case of a short to battery.
