You could always take a 9V battery, an LED, and a DVM to check the current. The LED will drop voltage from the 9V down to where the SSR can handle it.

thanks for the reply.

BTW what if i use a SSR which will give me a current output of only 1A MAX, as i need to light up a bulb which is only 60WATT and according to the following

P = IE
I = P/E = 60/100 = 0.6A

So i think i can use a SSR with following attributes

IN: 4~7VDC
OUT: 100~220VAC
Current OUT : 1A Max

Whats your say on this?

The output specs are fine. The input, we don't know until you measure the current.

My guess is that it will work fine as it.

Ya thanks for the reply.

BTW its a good idea to solder the AC wires before connecting them to SSR? Is it safe and recommended?

Nope. Downright dangerous matter of fact. You are better using crimp connectors and using the built in screws on the SSR.

In the US of A the AC line cord will normally have a polarized plug, narrow terminal is hot-black wire the wide terminal is neutral-white, if a third terminal U shape is safety ground[ earth] , no connection on your ckt.,unless it goes in a metal box.

Actually any SSR only connects to the hot lead, similar to how you would use a SPST switch. The Neutral and Ground are not involved.
