Contactors are used for switching more than 15 amperes or in circuits rated more than a few kW. Except for optional auxiliary low-current contacts, contactors normally have open contacts and are used ...

Abstract: The stage division and state recognition during ac contactor degradation process is an important prerequisite for realizing its self-perception. In the recognition of its degradation state, ...

Solid State Relays (SSRs) and Solid State Contactors (SSCs) are ideally suited for controlling dynamic loads such as motors, particularly where frequent or multiple start/stop cycles are required in ...

Abstract: Fault current levels vary in microgrids due to the plug-and-play nature of distributed energy resources (DERs) having different operating modes. This results in maloperation of time-graded ...

When voltage sags occur inside or outside of a facility, properly placed power quality mitigation technology will save sensitive equipment from costly shutdowns. The cost of this mitigation equipment ...

We have received the Seeed Studio 2-Channel Wi-Fi AC Relay for review. It is an IoT/Smart Home device featuring a 2-channel relay (wet contact) that operates over a WiFi network, and provides an ...
