Hi! Welcome to product review and theft by Robojax. My Name is Ahmad Shamshiri. in this
video we are going to do the test and review of this 1400 what AC demo and indeed it goes
this is how it does how fast this is heating up heard the set up for testing a toaster
I purchased this from eBay for dollar eighty-nine cents and depending on where you get it from you
might pay different prices but this has been labeled as 2kW and you can search for 2000 watt
AC motor speed controller you will get it here. I will provide you the link in case if you want
to just click on search and this activate it written as two kilowatt I will have to
test it and see if this can handle certain load so the claim on eBay is not trusted
My name is Ahmad Shamshiri and presenting this tutorial form Canada.
let me explain the hardware the main Triac here is BTS 16600 B and then we have a diet
here that is firing the gate of this we have main potentiometer that you dim the light and
there is adjustment depending on sensitivity of the load you can adjust this the rest are
just a small components we have two resistors and then the two capacitors I searched online and I
found the schematic diagram for this this is the input here they wrote it in English the rest is
Russian but it's very clear this is the input and that the output this is our BT a 16600 that's our
track and we have a director this is a snubbing circuit that is suppressing unexpected hysteresis
or change in voltage to provide you the link for this document from analog device 1847 and here
it expects it explains it that the track under the RC snubber circuit here the exactly hundred
ohm resistor with 0.1 micro farad 400 volts capacitor and if I show you that this resistor
is 100 ohm as you can see this is 100 ohm that is just Assessor in series with this capacitor
and then this resistor is here and this is 4.7 kilo ohm resistor which is this one with the
same capacitor 0.1 micro farad 400 volts so these two are here let me measure that I'll show you
so that's 4.6 4.7 kilohm and this tremor is written as 2:05 that is two zero and five
zeroes so that is it to megohm tremors and then here this is the main potentiometer and this is
500 kilo ohm so that's two mega ohm with 500 kilo more in parallel to achieve certain value and the
current goes from this way to the track and we have here a capacitor this is not changing so
you can control the angle of fire here of this track and this is the output to the load which
the neutral line is directly connected so we are just controlling one of the wire or the live wire
the length of this module is forty eight point two millimeters or one point eight nine inch the West
is thirty six point four millimeters or one point four three inch the depth is thirty point three
millimeters or one point one nine inch and if you want to know the weight with the knob is 40 grams
Datasheet viewed
here's a data sheet for BTS 16600 be the pants are from left t1 and then we have t2 and then
the last and is gate the maximum current that it can handle is 16 ampere and blocking voltage
of 600 volts so in terms of power it can handle 16 ampere but not with this small
heatsink I'll provide you the link in case if you want to have a like look at it further
Wiring explained
that you will connect your input at this point this is a wire that I have in Canada this is a
plug and I've connected it to this point actually this were a piece of ware which I just cut it and
to is connected in here and then that this is for the load and I'm going to connect the load in here
Small motor demonstration
and here I found this fan that can fit on the screen and you can see it powered
everything up let me connect this in now it is connected and this is on
now because now this is maximum but I know this fan is now not running
at maximum so perhaps it needs some adjustment
clockwise it's not helping let's go counterclockwise
yes increasing
so, we're a very small window of control this is not
the reason that this is not controlling it and a full
rotation is to have this will work with 220 volts properly if you rotate it fully
you
Demonstration to reduce to power of bread toaster
and have a fit up for the testing a toaster this shows the input voltage 123 volts at
the moment the floor is not connected I am going to use this toaster connecting
it and we will see how much we can dim or we can reduce and see how much power this
can handle now this is a setup and the voltage is 124 volts now I've said this
to maximum and this is the toaster let me turn it on 800 watt and so let me reduce it
so, we have reduced it to 300 watts let me go to zero what happened a total is turning off so
I have to be a certain level when I go to the maximum that's 872 Watts 870 watt 7.37 ampere
let's leave it like that it's heating up my doom let me take the thermal image
and let me turn this on let's go to the maximum so it doesn't turn off quickly now let's see how fast
this is heating up using the thermal camera 68 69 degrees 73 72 degrees 75 so that's very normal
80 81 degrees so this is very normal now the temperature is good 84 85
degrees let's see how much it heats up but my toaster will
turn on turn off soon 330 degrees I've disconnected it when I touch it is hot
Demonstration of dimming a light bulb
initially will I receive this it was not dimming up fully the light the reason for
that was for example if I turn this around fully if I turn this fully low
so the light was like death I could increase the brightness and when I was decreasing it was at
this level this is a hundred watt tungsten light now let's test if this luminous 15 watt LED the
intensity of light of this one is 1550 luminous so the old wattage is now over we just measure
the intensity of light by the luminous and we don't care about the power of wattage because
sometimes they may make it very efficient and you get higher rating so for us the energy
can be consumed and the luminosity of the bulb is important and this and they are offered in
different daylight tungsten and differentiating this is now four hundred and twenty volts but
it will act with the same way with a different voltage let me connect this now the demo is on
at the dim light this is how it does it just blinks like this because it's dim now if I
increase this slowly dance but at the maximum at the maximum you saw that it is working perfectly
but if I decrease the right this is what it does so this doesn't work with all this is a different
lead alight very low power now if I reduce it this is now working but the intensity of light cannot
increase or decrease fully let me just reduce this fully - to adjust this make sure to put a tungsten
light because for sure you can see the intensity and then let's put this at the minimum now this
is at the minimum but still we can see that line you want to make sure that we don't see anything
still I see red right now it is totally off and if I go to the maximum I'm not sure if
we are getting maximum or not let's rotate this to see if we are getting more than this
by rotating it to the maximum now it's clicking you can hear
the click so now let's go to the left to the minimum and this time because I
know the maximum it didn't work so let's put this back to the minimum
I want to make sure that we don't see any of it still I don't know if you can see it
in the camera cell there is a red wire let me rotate it towards the camera so you can
see it you see that red wire it's still it hot area is hot and let me adjust it further now
it's totally off but I we cannot see it and now let me increase it and indeed it
goes to the maximum and have what a death at the minimum and at the maximum it just works
now I'm correcting a different vault this is a
different brand EcoSmart 120 volts 19 milli ampere does 800 luminous
there is now at the maximum and let me reduce it so this is perfect this
is dimmable but when I go to the 0 it cannot go to 0 but from the certain
value above let me turn this more from here maybe we have more dimmable value
so no and that's the money one that it can go still there is some light but it's very
dumb and as I rotate this you can see that it can increase so let me get it
off the screen so you can see my hand so make sure if you are using this developer
device make sure to get the right type of LED bulb some of them are been labeled as dimmable
Conclusion remarks
the review of the so called two kilowatt AC dimmer or AC light speed controller my test
with 800 watt load showed that yes if heating up significantly and the amount of power that
is going here with a voltage and the current was that depends on your location to the current was
seven point 5 ampere acting on current that this allowed was seven point 5 ampere and if
you see seven point five times 220 volts so you can control 1650 watt but the amount of
power that passes he has 7700 1600 watt this is not capable to handle it because it will heat up
significantly so the total power is at the end important so this cannot handle any power above
800 watt it will heat up very quick you need huge heatsink with Carol hating it cannot handle it
