3 Tested 220V High and Low Voltage Cut OFF Circuits Using IC LM324 and Transistors
An AC mains high/low cut-off device will cut off or disconnect the mains supply from home electrical whenever a high voltage or low voltage situation is detected. In this way it ensures total safety to the home wiring and appliances from fire hazards, due to abnormal over voltages, brown outs or low voltages. In this […]
220V Solid State Relay (SSR) Circuit using Triac and OptoCoupler
An AC mains solid state relay or SSR is a device which is used for switching heavy AC loads at mains level, through isolated minimal DC voltage triggers, without incorporating mechanical moving contacts. In this post I have explained how to construct a simple mains operated solid state relay or an SSR circuit using a […]
