    Relay working detection

    I'm using two relays not to increase the power but because here in Europe we are obliged to underbreak both of wires when the device is used in a wet area (bathroom, outside, place where you clean and dry (I don't know this word in english),...) The only relay which passed the test is the RT...

    Relay working detection

    Well, because I have no other choice - due to the small package I have to use two single pole relays with the coils in parallel. So I 'simulate' a double pole relay. You cannot find a real double pole relay which can drive 16A. It doesn't exist. But the problem is that if one of the two relays...

    Relay working detection

    The relays are Schrack RT31L12. The problem with this relay is that the minimal voltage must be 12V and the minimal current 100mA. Thus, 1.2W ! If we extrapolate, we can say that with 230Vac the current should be about 5mA. But this makes always 1.2W when the relays are OFF. Which is most the...

    Relay working detection

    With two change-over relays I simulate a bipolar one. NO I CAN NOT USE DIRECTLY A BIPOLAR ONE. Why change-over? Because I want to use the normaly closed contacts to know if the relays are well off. My problem is that the NC contacts must have minimum 12V 100mA the ensure a good working (no...

    High voltage ac to dc converter.

    You can use a Thyristor Controlled Rectifier (Half or Full Bridge and even double full bridge)
