Technical indicators: voltage:DC12V-DC72V(Single Phase) max load:30A working distance:300mProduct pimensions : 3.3x 2.1x 1.1 inchesPackage Includes:2 x remote controls1 x SwitchCable length of antenna: 4.3 inchesBattery model: alkaline 12V 23A 1 x Manual NOTE: Choose the style what you need :First,confirm the voltage of your equipment. For example,home appliance is 110V, you should buy the 110V-240V item, The car equipment is 12V, you can buy 12V-72V items.

Review: Response is fast, range is good, very simple to install for my use. I was slightly surprised by the wiring. The relay accepts positive and negative inputs and outputs positive and negative outputs. This was ideal for my application, but it is not obvious to me whether it could support a scenario where the control circuit is one voltage and the relay switched a load at a different voltage. Fortunately, I didn't need that capability.
Review: Worked as advertised. Used to to add an exhaust fan heater to our bathroom. Rather than run a new line to a switch I just put this in series with the wire. I’m only triggering it from about 10 ft away, so can’t speak to the length of signal distance. Quality seemed decent, but there’s always a thought in the back of my mind that it might not really be 30A rated. I’ll let y’all know if my house burns down.

*by C***O on 4 November 2023*

We have this on our well pump and it's great. We also have it on our water intake pump which is about 100' below our house and it works great. We are very happy with these and the 2 remote units don't share the same remote code so you don't accidentally turn on another pump with the other remote. They are easy to install and last a long time.
