Figure-1 shows the schematic diagram of the device. P1 is used to connect the 220V-AC input and the ON/OFF switch to the circuit. C1 is used to reduce the AC voltage. The value of the C1 also ...

The easy way to measure high AC currents is to use a clamp meter but these are generally quite expensive and cost several hundred dollars at a minimum. Add-on clampmeter adaptors can work well but ...

Pulse Electronics Corporation introduces its new Sidewinder™ AC current sensors. Sidewinder products differ from traditional current sense transformers because they do not need a core. This makes them ...

When working around mains voltages, it can be useful to know whether a given circuit is live or not. While this can be done by direct connection with a multimeter, non-contact methods are available ...
