Solid State Relay for PID Temperature Controller SSR-40DA 40A 3-32V 24-380V AC

After several tests and connection methods the item worked as expected, input voltage controls switching method. The output was connected to an extension lead, I tested light bulbs, heaters, kettle and also transformer based power supplies and it all worked. The relay is of good quality , a bargain for the price. I also attached a heat sink for safety / keep cool.The basic connection method is the positive from AC source goes through the ~ signs (input / output) and the negative connects directly. Input control voltage goes with the + - signs. As i connected it to a extension lead with a light indicator, I did not get any flicker when left on, it was consumed by the ON light.Would Recommend......

Avoid. Dangerous. Blew up within seconds. Replaced with another brand that worked fine.
