Sonoff Basic

Hello can you tell me if a 150watt light bulb 240v will be ok for the Sonoff Basic

thanks


So I just these sonoff basics from Amazon. Box says basic, board says RF , the main traces have been replaced by wires, it's using an esp 8285 and I think I see a fuse. Did sonoff completely change their manufacturing or is this a knock off?

15 x 15W = 225VA / Voltage = Amperage.  So if your line voltage is 120 the 15 lights require a total of  1.875 Amps.


For an inductive load like LED transformers I would keep the Sonoff basic load under 7A to protect the relay contacts.

Then you have an inductive load of 225VA.  Divide 225 by your voltage to get amperage.


For inductive loads I would probably try to stay below 7 amps.  Inductive loads put more strain on the relay contacts.

"15 watts led panel light total 15 pcs"


15W * 15 = 225W or 225VA


For 120V circuit:   225VA / 120V =  1.875A


For 240V circuit:   225VA / 240V =  0.938A


The Sonoff  basic is rated at 10A into a resistive load.  If you are pulling a heavily inductive load like a LED or CFL transformers or ballasts I would derate it by 30% to get the expected life out of the relay contacts.  For that type load 7A or less should be okay.

150VA / 240V =  0.625A   The basic is rated at 10A  so yes, it will handle it easily.
