6 VDC Coolant pump

Post by Skunk »

I have a marine bilge pump that I'd like to use for coolant on my knee mill. Is there a way to get 6 VDC out of my Allin1dc ?

No, but you don't get power for the coolant pump "out of the Allin1DC" in any circumstance.

You need to find and install a suitable DC power supply, and a relay to switch it with. Then you use the Allin1DC output relay to switch the coil of the relay that in turn switches power to the pump.

In the unlikely case that the pump only draws 1A or so, then you could switch its power directly using the output relay on the Allin1DC. If the pump draws more current than that, you will want a larger, replaceable relay in between.
