Alternating current (ac) or direct current (dc) circuits are capable of carrying very different currents, as illustrated by the ratings on the switch in Figure 1. This is why it’s so important for ...

The ACSN100-AE-F AC current switch has a fixed setpoint of 0.5 A and monitors current up to 100 A. The normally open solid-state switch output rated for 120 VAC/DC, 0.15 A and has a small size, making ...

This AC power switch circuit senses the presence of AC current in one outlet of a multi-outlet power strip and switches power to the remaining outlet(s). It utilizes a current transformer, single ...

When choosing a switch to use in an electrical design project, there is a perception that it is possible to use any switch, provided its current rating is greater than the maximum load in the circuit.

Switching regulators with integrated power transistors provide simplicity, require few components, and make compact step-down power supplies. Few of these devices can supply more than 5A load current, ...

Power relays are specifically designed to handle either AC or DC. It’s important to know the fundamental differences between them before building them into a system. Introduction to AC and DC Power ...

The GFS series of ground fault sensors monitors all current-carrying conductors in grounded single and three-phase delta or wye systems. Available in fixed-core models, the GFS series features ...
