Agreed with your suggestion of drift limit.
But you can see in the data that they mentioned + 25°C, 1.5 h “ON”, 0.5 h “OFF” too. And here load would is expected to run 24 Hours, temp. +25°C is also not possible to maintain. So if we run the load at 50% then on what basis we can say that it...
Because there is need to consume 60W power that's why we want to do. It would be applied in parallel with a product because we overall system on which product is applied, coming under load condition. So to bring the overall system out from under load, we need to consume 60W load.
If temp. is maintained with the help of heat sink then what about life of resistors. Vishay resistors are showing 1000 Hours life and application need at least 30,000 hours life.
Heatsink solution will be used but first trying to see how much lower temp. can be achieved without heat sink. Otherwise there is very good heat sink which has many fins so heat dissipation would be good.
Try to get temp. as low as possible. Due to application and place limitation temp. is the...
"Wire wound solution is there but high temp. and life of resistors problem is there." Resistors becomes so hot which is not acceptable at all.
You are right that heat dissipation will occur. I wanted to use heat dissipation in other sentence but missed that sentence and by mistake used in wrong...
Hi Friends,
Today let's discuss something interesting and different on the loads available for AC Voltage-240V.
If someone has to connect a load which could consume at least more than 5W at 32-40V AC & max 50-60W at 240V AC.
Operating hours are 18-24 Hours.
Wire wound solution is there but heat...
Is there no other technical person who can identify this IC (LED Driver IC) ?
I think it's chinese brand IC due to which it's little bit hard to identify.
But is anybody can help me in this matter then it will be very appreciated.
@pranam77
I am agree with pranam.
So you must not use the power supply of same rating as your load require. You have to use the power supply(cv-constant voltage) and whose rating should be more than your load.
In the market the LED strips operated by 12V are available in the market so you may...
Thank you so much for your kind and valuable reply.
Shashi,i am little bit confuse because if we consider that pin no. 7 & 8 are D1 and pin no. 5 & 6 are D2 then the pin no. 5 & 6 as well as 7 & 8 should be short internally. But wheni check the continuity from multimeter then there is no...
I have an IC, the above screen printing is:
The first rows of 3620-00
second row is the MS2PA
third row is AB0939
The package is a SOP-8.
So can anybody tell me that what is the make of this IC and from where i can get the IC and datasheet?
I want to get the info as soon as possible...
Dear All,
Which component is responsible for filament current in T5 Electronics Ballast?
Actually, i am designing an electronic ballast for T5 2x24 Watt Fluorescent lamps. But the filament current is approximately 60-70mA. So can anybody suggest that how can we increase the filament current in...
Dear if u don't have any load of 0.2A then u can connect a resistance of 2kohm at the output side for the purpose of 0.2A load.
But resistance should not be less than of 80W.
Thnaks & Regards

For C:
X=1/W*C
W-->Angular Frequency
Where W=2*Pi*f*C
Condition (1)When we are applying AC
then for AC f=50Hz(india)
i.e.there will be some reactance
so Capacitor will pass the AC.
Condition(2)When we are applying DC
then for DC f=0(zero)
so the X will become infinite that's why due to so much...
simple charge controller circuit
