Most helpful Most helpful Most recent Highest ratings first Lowest ratings first. You’ll need an SSR rated for inductive load, usually a random — type not zero-cross type.

How to calculate safe margin? I can turn the SSR on and off fine with the Arduino, and can have it power a decent sized load okay I can have it turn on and off a heat gun plugged in to the SSR controlled extension cord just fine.

Assuming construction is similar to what we found, it appears that as long as they are derated down to be within their 12A limit and have good heat sinking at higher power levels over maybe 6- 7A, they should probably perform OK. Hi, Sounds like you are getting ElectroMagnetic Interference. It prevents relay from 25daa triggering due to voltage spikes on AC line.

It has a long operating life and high reliability, compact size. RL Choose size for availability notification: Amazon Renewed Refurbished products with a warranty. No other external components are required like you would need transistor switch for mechanical relay. As you have clearly shown, even that may not be a safe assumption unless you sacrifice one out of every order to see what is it that you actually received. Notify me of follow-up comments by email. If you have any further info on this topic or corrections to the information I have found and provided, please feel free to share.


Get to Know Us. Using relays are common way of switching high power loads with electronics. It has a maximum load capacity of 12A. Update your profile Let us wish you a happy birthday!

DC-AC – Leakage current in state: You can operate without heatsink if load is switched in periods, but for constant driving it would be better to use minimal heatsink to lower junction temperature and extend operating life. Below that is the label from the parts that we received.

A half US AC cycle is 8. MarkT Brattain Member Posts: After paying for this item you will be awarded: When I plug foteek chest freezer in directly to the mains electricity it draws about 55W on a continuous basis when running and after the startup surgewhich indicates that the inrush surge is about 10x the continuous current, which is about what is expected.

This ensures that switching is always performed at safest moment to minimize RFI noises in line. Share your thoughts with other customers. But if ambient temperature is high enough, then you need to use heatsink. Amazon Rapids Fun stories for kids on the go. Ask for this product: Write a customer review. Product details Item Weight: Try just putting 5V on the SSR control.

And there you have several options for switching loads. What other items do customers buy after viewing this item? Elec guy 12 November, at 9: Sponsored products for you. Best way to do this is to attach heatsink to backplate.

How is this physically wired? As with any new product, before we offered them up for sale we tested our first shipment of these relays that fotel in the door.

Is that ok for a 10A load? Robin2 Brattain Member Posts: Customers also shopped for. 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.

Ours ran comfortably at 5A and swr starting to get pretty hot up around 8A with no heat sinking.
