Amazon Inspire Digital Educational Resources. I think the present relay is rated at 16A or 20A AC v system.

Get to Know Us. I don’t dare use them unattended.

RC snubber circuit reduces those spikes to ensure safe and reliable operation of SSR.

We will send you an SMS containing a verification code. It has a long operating life and high reliability, compact size. September 13, at 3: LED light – Weight: You can click to enlarge the pics. If you take any microcontroller or any other digital IC, you will see that their output current on single pin is very limited — varies around 20mA. Below are a pic of a genuine relay with some key items to watch for.


I know about inrush surge current when a compressor szr but it should be well within the limits of the SSR. Here is a link to a UL notice released several years ago about fraudulent use of the UL logo that calls out some of the signs of fakes that were identified at that time.

Try just putting 5V on the SSR control. Fridge motors are induction motors, you need an SSR rated for such a highly inductive load with the right snubber circuitry. After paying for this fotwk you will be awarded: Don’t see what you’re looking for? How to calculate safe margin? Using relays are common way of switching high power loads with electronics.

I am not sure if the SSR is real or not, and some reports that there are fake ones that are underrated.

Last thing to discuss on SSR is power dissipation. Same situation is with voltage.

Looking at these relays for sale on the internet, it appears that the vast majority are fakes from what I can determine. When you sign up to be notified, you hereby agree to receive only a one-time notification of a product re-availability. Customers also shopped for. Do not underestimate the size of the inrush current. As you can see in this particular relay a snubber circuit is already included. They also take large currents at start up so the current handling must be up to scratch.


But it shuts off after a few seconds.


November 16, at 8: Sign me up to an availability notification. No other external components are required like you would need transistor switch for mechanical relay. Yes, there are lots of reports of counterfeited fotek fohek that are dangerous, never buy mains-rated equipment you are not sure of.

They also appeared to be counterfeit and came from the same supplier, but I could not find any performance issue with them during testing and they were built with 80NF70 MOSFETs which should be up to the job to meet the full spec. See more product details. And there you have several options for switching loads. Relay is triggered through zero crossing detector.

Let us wish you a happy birthday! Usually we need to switch loads that draw significantly higher currents and are powered from higher voltage supply.
