Any time you are working with burglar alarm, access control, sound, nurse call, or intercom systems, as well as computer networks, lighting dimmer controls, and low-voltage industrial controls, you ...

The transformation of the power landscape involves more than just generation. The distribution of electricity is being changed as well, with technology designed to make electrical systems safer, more ...

ABB, the leading power and automation technology group, has launched Emax 2, the first low-voltage circuit breaker with integrated energy management functions that monitor power usage and control ...

H-bridge buck-boost ICs are widely used in applications requiring a constant voltage or current source even when the system battery drops to lower voltages. They make sense when a single-stage ...

A ripple-generating circuit is usually needed to ensure stability of constant-on-time (COT) controlled buck converters. Different values of the ripple generating circuit can have direct impacts on ...

The Machine Primary Control Elements (MPCE) 1 and 2 are typically a relay with force guided contacts. When a safety interlock, light curtain, or e-stop switch opens a circuit, the MPCE NO contacts ...

As electronics applications continue to become more compact, powerful, and versatile, the final system demands and complexities of mobile and stationary devices also are becoming increasingly ...
