Current Sensing Switch Dust Collector

With this easy to use dust collector switch youll be amazed at how much cleaner renovation work can be. If you dont have a blast gate to automatically open close all you need is a current switch and a relay much less expensive heres an example of a current sensing switch. Total cost for this project was under 100.

Diy dust collector system with homemade blast gates and automatic startstop function duration.

Current sensing switch dust collector. Instead it is used to switch power to a contactor big ol relay that actually switches the power to the dust collector. If you do have a manual blast gate to open close you can just wire a small limit switch to the blast gate to openclose the relay for the dust collector. Tool controlled dust collector. I used an arduino two relay boards and current sensing transformers to automatically turn the dust collector on whenever a tool is switched on.

Google current sensing switch and youll find a lot of relatively cheap products. Then you need a 2hp rated switch single pole wired to the load leg of the ssr the unpowered side. Please check the ratings of any current sensor switch and the demands of the application. The current sensing is done in a non invasive way that does not require modification of the circuit being monitored.

Here they are not hard to find. In a first class woodworking shop the craftsman merely pulls the trigger on his power tool and the dust collection system turns on too thanks to a device called a current sensing switch. I dont think there is a current sensor made that can handle the 20a 30a continuous required by larger dcs. Automatic current sensing switch for dust collector marc ammons.

Those are cool but pricey. Automatic vacuum switch with extra outlet for power tools etoolcity unique current sensing technology to delay vacuum onoff to prevent circuit overload eliminating circuit breaker tripping 47 out of 5 stars 371. Use those contacts to switch power to a relay that controls your dust collector and bada bing you have an automatic dust collector. Build an automatic shop vac power saw switch.

The ivac dust collector switch box is an inexpensive simple to use automated dust controller that activates your shop vacuum automatically whenever the power tool to which its attached is turned on. Ok so my shop is just a tad less than first class but i. The current sensing relay will switch when it senses current allowing the 5v dc to pass to energize the ssr which will allow your power contacts on the ssr to switch turning the 115v dust collector on. The longer the circuit will take to switch back off after it stops sensing the load being monitored.
