heavier plating on the Mini would help it stand up to that stated 150ma max
current draw for longer before giving up the magic smoke.
If you exceed the 150ma the driver chip will give out the magic smoke, not the board
traces. I know from experience.
> I thought the Anvilus Mini did proportional control. I thought it decodes
the signal from your radio equipment and gave a 12v DC PWM output meant to
control high amp relays. You are however telling me this isn't true?
Correct, the Mini does not do PWM.
> But if we are making the distinction like you are
making then I'd have to ask, if I did use just plain old spring loaded
magnetic coil type relays like they teach you about in early electronics
courses and not solid state ones, wouldn't they NOT be able to cycle fast
enough for PWM applications? Don't they have a maximum trigger frequency
some what decided by the weight of the switch mechanism they use? Is this
maximum frequency listed on their spec sheets?
If you try to PWM a mechanical relay I would imagine you would soon destroy it due
to arcing at the contacts.
