Last year I bought a nice baseboard heater with a digital thermometer, but it's 120V/1500W and with the old wiring it blows a breaker once in a while, which is annoying. Als|

Lastly CX3407 Main B-Plus Filter Lytic
Have fun :)|

|07-01-2009||Sounds like you may have some knowledge about the theory, but a bit confused.... heater is a passive resistive load and using a rectifier(regardless of the size) is not going to cut the total power in half. The whole concept of conduction is valid when co|

Effectively, you are changing the AC to a halfwave DC. A resistive element on the receiving end, still exhibits the same resistance and the total current draw stays the same--it will simply attempt to dissipate the energy thru |

I believe it may have been manufactured by a company called Vestel, but I'm not sure. Is there a service centre anywhere for Techwood LCD TV products in the UK?
|07-01-2009||By connecting a half wave rectifier in series with a resistive load, you will get the half effective power in the load. But the RMS value of the current will not drop to half its rated value, just to 0,707 times its rated value. And then it depends, wheth|

If it is supplied with mains voltage, then an easy check would be to try supplying it via a Variac, disconnect the secondary from the cascade and|
