This smallest portable Ammeter and Energy Meter Device in the size of a coin, capable of performing the same functions as a ...

To enable system engineers in the EV industry to take the next step towards transformer-less OBCs, LEM has designed the first automotive-grade residual current monitoring (RCM) type B sensor for ...

The basic principle of the system is to inject a signal onto the power lines at a much higher frequency than the 50 or 60 Hz of the AC power itself. Using both active and passive filters ...

AC power sources provide output often with adjustable ranges of current, voltage and frequency. They are used in testing motors and many other kinds of electrical equipment for which input values may ...
