I'm designing a circuit to control my pool cleaner booster pump and am not sure if I need just a relay or a more complex circuit. Any advice on what I need is much appreciated.
I have a variable speed main pump which draws different current @220v depending on the speed I run it. It is fully programmable for speed, duration and time on and off via an onboard computer. I need to run my booster pump (either 110v or 220v) during certain times when the main pump is running full speed.
What I want from the circuit is to monitor the current draw on the line going to the main pump and when it is above a certain level (which I would ideally like to be able to set, but will know what that trigger current is so I could buy something set to that point) turn on the other pump.
Example:
Main pump turns on drawing 300 watts, switch does not come on. Main pump increases speed and draws 600 watts, switch goes on and turn on booster pump. Main pump cuts off, drawing on 50 watts, booster turns off.
Thanks
