Smart Capacitor power supply


This capacitor power supply can deliver 12 volt DC and 100 mA current to power low current devices. It is provided with surge protection and is totally isolated from mains supply using two capacitors in the phase and neutral lines. So the connected device is safe even if the phase and neutral lines changes.

Electrical Safety


Electricity has very much importance in human life. To run an electric appliance or electronic circuit we need the help of electricity either in the form of AC or DC. Even though electricity is useful to human life, careless handling can cause lethal effects. Electrical safety measures are necessary while dealing with high voltage AC available from the power grid. Ignorance can lead to a fatal shock or fire hazards. Let us see how electricity poses lethal effects on the human body and the safety measures to prevent it. Remember, Electricity travels at the speed of light. Its flow is around 299,460 kilo meters per second so you will not get time to react because you can’t move faster than electricity. So the best way is staying out of its way.
