Questions & Answers
A minimum voltage of 3V DC is required. Neither it nor any of its components are designed for AC input voltage.
Screw down clamps are used on the terminals. They have three pins each. There is a maximum opening of 5mm. Featuring a 7mm shaft with a phillips hex head, the screw measures 4 mm in diameter.
sure how it's measured, but it's in milliampers. Current is more affected by voltage than voltage is by current.

Sorry, I didn't realize that SSR might not be the best alternative for me. However, this item does exactly what it's supposed to do. You might not even be able to load it at 1/4 of what it's supposed to to handle constant loads. The specs say 40A, yet even a 6A load over an hour will cause it to heat up significantly. There should be a heatsink attached (arrived today), but I think solid state drives are to blame The purpose of state relays is not for constant loads at all. In order to control a pair of exhaust turbines that pull about 1200W each and spend 70% of the time in the "on" state, these relays are unfortunately not suitable. The electromechanical relay I need for my purposes is not available. In addition, make sure not to use a typical desk lamp to test this relay. Blinking on and off is what you'll see. A small amount of voltage leaks through in an "off" state and the typical light bulb acts as a capacitor which leads to a much larger fluctuation which causes the lamp to blink every two seconds. I can do it in three According to what I read online, most SS relays have this feature, so nothing wrong with the one I have.
As a combination with a PID controller, this type of SSR is common. It allows you to control the voltage output for your burner when you use a PID in a brewing application. In the pros column, you will see that * Small and compact in size and weight. * Good cooperative price. * In the cons column, you will find that * No heat sink grease is included.
Having mounted mine to a CPU heatsink with a fan, the SSR did not even get warm to the touch even after passing continuous 16A at 120V for an hour. I also can switch on and off my 120VAC load using a 12VDC PWM signal from the relay with no problems. There is no way I know if this relay has counterfeit TRIACs in it, or if it could handle 40A, so if you plan to use this SSR, you probably want to run it at a fraction of its rated current with an oversized heat sink. It is good to know that the maximum current of most home circuits in the US is 16A, so this should be enough for most uses, unless you have funky Make sure you have a way to remove the heat so that you won't have to worry about this thing malfunctioning.
A feature that automatically starts the dust collector when either of two power saws is turned on.
The output of this system is approximately 15 amps over about 30 seconds, using 12V to switch 120vac. I used it maybe 10 times before it 1/2 inch thick aluminum is used for the heat sink and it measures 6 inches by 12 inches. The compound was used to cool the heat sink. Despite the fact it's incredibly big, it was on hand when I saw it.
This item was used for my dust collection system so that I could turn on the dust collector by using low voltage microswitches at the blast gates. This system is great and since there is a gate at every tool, it uses a very efficient method with the system coming on when a gate is open.
In order to operate my oil-powered device, I purchased this product to enable and disable it using a low voltage control The air compressor is not used as much. The installation process is straightforward. I have an air compressor that consumes about 16 amps when it is operating at 120V. To date, this solid state relay is performing in accordance with expectations. I believe it does state that a heat sink is required. I only run my air compressor for up to a minute or so at a time, so I've noticed no heat emanating from this device. I simply mounted it in a 4x4 square metal box with a smooth back and used some heat sink goop on the The heat sink on top of it seems to help. There was a spare 4, so I used it. A 5VDC cell phone charger with the end cut off is used as the control voltage DC source. I have no issues with it.
With this switch coupled to an Inkbird Temp Controller, you can relay switch the heating elements on and off according to what the controller needs from you to keep the elements at the prescribed temperature. Mounts easily and is easy to wire. This relay is excellent for elements that need to be heated.
