I would run with Eric's suggestion of using heaters, I like the reference to "electric fire". I would also suggest that when doing your testing you instrument your plug/outlet connector to monitor temperature rise over time under given loads. A connection which seems fine when plugged in may start getting warm and begin to fail after a period of time. Temperature rise of the connector over time can be an issue.Hi,
I want to check the max supported wattage (output) of a smart plug to check if it is suitable for use with heavier appliances. Is there any test equipment I can use to simulate an AC load of 2000+ Watts or 10+ Amps @ 240 Vac?
Thanks in advance
I have one or two and gave that suggestion some thought but unless newer ones are better the older ones only get to about 1875 VA and the thread starter was looking at 2 KW. The early ones were also 120 VAC versions I know they did start making 220/240 volt flavors but I don't know their limits. Would be a nice solution though. Inexpensive and off the shelf.
I should have clarified in the opening post itself, the smart plug currently comes in <1500 W version, and the manufacturer is making a 2500 W version for a client of mine so I need to independently check whether it will hold itself at those wattage or not.Here is a dumb question. Why not just look at the specs of the smart plug and see what it will handle?
"Testing" the plug for "supported wattage" is a good way to burn your house down.
Thanks Eric, I will look for a 2.5KW rated heater and run it.hi,
You could use a 2KWatt electric fire. They are usually two 1KW elements in parallel.
Will test it for a minimum of 2 weeks before handing it over to a test facility. They want me to do a preliminary qualification test before spending the money at a professional test fac.This is dangerous, keep it under your supervision for the first week at least!
Yes I am thinking about that too. I have a decent setup for DC devices, mostly USB chargers but nothing much for AC devices.The best option for tests done by someone (at home or work) is to have a setup environment for that. If you intend to do this on a regular basis, it might be better to start setting up the environement (this should be your next thread).
