D5 PWM input?

      D5 PWM input?

      Hello hello,

      I'm working on a standalone pump/fan controller here, one that has automatic flow rate regulation with the D5 PWM pumps. However I'm having a hard time finding relevant data for these. Specifically, I need to know the PWM input frequency range. How high can I go? Can anyone help?

      Thanks for the input!

      Yeah, I'm aware of the 4-wire fan spec... it's just that it's a fan specification and that I don't really have anything other than an assumption telling me that the pump will - probably - accept the same PWM input frequency range. I wasn't able to locate any sort of decent datasheet either, not even by contacting Laing directly.

      I guess there's not much to do other than learn from experimentation, eh?
