I was trying to switch some AC appliances (Ceiling fan 75w, LED bulbs etc.) Till now I had tried switching using bt136, but I am planning to take it to another level. So this is what I came up with so far, 1) I will need a MOV for over voltage. 2) Snuubers on triac and gate 3) Some inductor to supress transients further (I am still reading a
I am working on home automation project in which 6 AC(230V) appliances can be controlled via mobile. i can easily turn on or off any switch using mobile, but some time randomly any appliance has been flashing in its off state. i am using MOC3021 to drive the triac bt136-600E(it is Sensitive gate,do not get non sensitive in my city),also using s
Sir i would like to make remote controlled ac fan speed controller with light on/off with pic16f877a with sony protocol in assembly language.i can turn on/off relay using sony remote by pic16f877a.and now want to use zero cross detector with bt136 triac but no any idea for how to develo a programm it.I can handle hardware and circuit for how to de
Hi All, With internet help I made one triac circuit to switch on my 230V AC portable vacuum cleaner. It works with some issue. When switch on the socket power, though I have not given 5v power at MOC side, the load gets ON for about ? second and turns off. 88805 I?m using bt136 600D , MOC3062 , 700 watts 230v
can any one help me schematic of "zigbee-wireless mesh networks for building automation and control" ?? i am using ARM7 that is lpc2148, MAX232 , zigbee module , triac moc3020 ,bt136 and the loads....... please help me its very urgent....... thanks in advance
Hi, NO ! you cannot use a ULN2803 for controlling a mains triac there is no isolation, use a proper opto isolator, many circuits around.
The MOC3020 thru MOC3023 series use a 400V phototriac output so any type can be used for 240Ac applications. And as goldsmith already mentioned, for a standard operation we must limit the optocoupler input current at 15mA-20mA, see the datasheet: In this particular application need to increa
Hi friends.... Does anyone uses the NI Circuit Design Suit 11.0????? I am having a problem in designing a voltage regulator with a bt136 triac.... I have decompiled the circuit by reading the values of components & connections from a fan regulator circuit... My readings are correct and I designed the same circuit in NI Circuit Design Suit 11....
A properly snubbed circuit enhances system reliability, is more efficient, and is quieter than an unsnubbed circuit. A properly snubbed circuit performs well over time, temperature and production tolerances. It is well worth the time to understand and use snubber circuits. www.engr.colostat
wat s difference between bt136-600 and bt136-600d
Hi, it was suggested to connect a serial 100nF + 100Ohm "complex" directly to the triac, also Leg1 & Leg2... Remember pls; "control is better"...:-) K.
can any 1 plss help me tht which triac should i use if i m controlling 12v dc motor intead of 220v bulb. rmember i m using bt-136 for bulb as a 220v dc bt bt136 is not working for 12v dc motor. kindly i m new help me plsss. here is the crkt dgrm working with 220v bulb bt not for 12v(12v from step down transformer) dc motor imag
Hi All, Is there a direct subsitution from a U.S. company for a bt136-600E triac ??? I'm trying to repair a burnt-out touch dimmer lamp without spending a fortune ( meaning a 50 to 100.00 minimum order for 1 triac ). Thanks !!! :-)
Hello That problem maybe the power of the fan. If the current is less that the I lacthing of the triac the semiconductor dont enter in coduction. Other problem is the power factor of the fan. If is to inductive when you fire at an angle prox of 0 the other part of the semiconductor cannot be fired becouse the corrent in the moment is not
What is the circuit between PB.0 and the triac's gate? Maybe you should consider optocoupler such as MOC3021, or similar? .. see picture below .. Regards, IanP
