My application is controlling home lights. I want to use relays to switch lights on and off. My circuit should work on all kind of lights such as neon lights, halogen lights, strobe lights and others. I should decide what kind of relay I have to use, EMR or SSR. I have read about solid state relays and I encountered two issues.
First, I know one of the limitations of the SSR is the leakage current. If it is 5 mA for example, the neon light my not turn completely off. The leakage current may be sufficient to keep the light on. Right?
Second, some types of strobe lights incorporate a diode in series with the coil or filament. This causes the light to behave as a half-wave rectifier. There is an RC circuit in parallel with the output of SSR. The capacitor in this circuit cannot discharge through the series diode, causing a voltage to appear across the SSR terminals. I know that SSR must see a zero voltage across the terminals to come on, it can’t turn on again in this situation. Right?
what is your final recommendation for my specific application. I am not really concerned about the life time because typically the number of contacts may not exceed 10 per day
