Geneva—STMicroelectronics has unveiled the ACST4, ACST6 and ACST8 families of AC switches that are designed to control appliance motors. The latest-generation ACST4, ACST6 and ACST8 switches include a ...

Due to the low current drawing, the circuit can be supplied from 230Vac mains without a transformer. Supply voltage is reduced to 12Vdc by means of C1 reactance, a two diode rectifier cell D1 & D2 and ...

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 ...

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 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 ...

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.
